Frontier open-weight models are shipping faster than the hardware assumptions around them. Kimi-K3, GLM-5.2 and DeepSeek-V4-Flash are closing the capability gap with proprietary systems, but releasing parameters only determines who can obtain a model — not who can afford to run it. Serving them still assumes datacenter-class GPU clusters, and as agentic workloads push inference demand up, that cost lands hardest on individual developers and small teams. Meanwhile, more than a hundred million consumer machines already carry discrete GPUs. A team of researchers from UC Berkeley and UT Austin propose FreeToken. The research team argued the missing piece is not hardware but a serving system: it treats a personal machine as a unified, elastic inference platform rather than a small GPU, and continuously maps computation and model state onto whatever GPU, CPU, memory and interconnect bandwidth the machine actually has. The result is a 35B model at interactive speed on an 8 GB laptop GPU, 284B on a gaming desktop, and the 753B GLM-5.2 on a single workstation card. Is it deployable? Yes, FreeToken is Apache-2.0 on GitHub, published on PyPI as freetoken v0.1.2 (uv pip install “freetoken[accel]”), and shipped as a one-click desktop app for Windows and Linux at flashml.ai. The CLI targets Linux x86_64 with an NVIDIA GPU on driver r580+ (CUDA 13). ft serve exposes OpenAI- and Anthropic-compatible endpoints on port 1919, and ft launch claude wires up Claude Code, Codex, OpenCode or OpenClaw against your own box. Who it fits: solo developers, startups and SMB engineering teams whose agent token bills already exceed the cost of a GPU they own; enterprises should treat it as an air-gapped or regulated-workload path, not a datacenter replacement. Strongest industry fit: healthcare and legal (data never leaves the machine), defense, finance, and IP-heavy R&D. Typical applications: local coding agents, private code review, offline contract analysis, synthetic-data generation, batch evals. The gap it targets Mixture-of-Experts makes local frontier inference arithmetically feasible. DeepSeek-V4-Flash activates 6 of 256 routed experts in each of 43 layers, so only 13B of its 284B parameters participate in any single token. Sparsity does not shrink the expert pool, though — at FP4 the full set is roughly 140 GB, so inactive experts sit in host memory and enter the execution path on demand. The research team isolates three failure modes in existing engines (llama.cpp, KTransformers, Ollama, MoE-Infinity): Prefill destroys sparsity: Thousands of tokens per layer route to nearly the whole expert set, so a prefill pass streams the entire pool across PCIe — about two seconds on an RTX 5090, five on PCIe 4.0 desktops, ten or more on the x8 links common in laptops. Static placement misses decode traffic: llama.cpp assigns MoE tensors at load time; KTransformers pins a “hot” subset. Routing shifts every token, so most expert evaluations fall to the CPU while the GPU and the PCIe link sit idle. Consumer CPUs cannot carry the remainder: Dual-channel DDR5 delivers 80–90 GB/s against the 1–1.8 TB/s an RTX 4090 or 5090 draws from on-package memory. Three mechanisms Bandwidth-adaptive execution (the q* policy): Because DMA transfers and CPU expert execution read from the same host-memory subsystem, a saturated PCIe link leaves a residual bandwidth of B_H − B_P. FreeToken splits each step’s m cache misses accordingly: q* ≈ m × B_P / B_H experts are filled into the GPU cache, the rest are computed in place on the CPU, and the two partial sums merge exactly — no approximation, no router modification. Both bandwidths are profiled on the deployed machine (ft bench bw), which matters: measured B_P:B_H is 52.7:77.3 on an RTX 5090 server but 11.8:47.5 on a 4060 laptop. Semantic-aware caching: During prefill, full-layer double buffering streams layer l+1 while the GPU computes layer l. Recurrent-state checkpoints are anchored at special-token boundaries — thinking blocks, tool calls, tool outputs — precisely where agent harnesses truncate context, so an edit re-prefills only the new suffix. During decode, a shared LRU expert cache spanning all MoE layers follows the router instead of a placement frozen at load time. Elastic memory management: At scheduler safe points the GPU expert cache is rebuilt under a revised VRAM budget without restarting the engine or reloading the host pool. Experts are read from disk straight into their final host layout, then pinned; no GPU warmup is required because the first request is served with a cold cache. Results On an RTX 5090, FreeToken sustains 77–83 tok/s on Qwen3.6-35B-A3B (BF16) and 22–25 tok/s on DeepSeek-V4-Flash (MXFP4) — 1.5–2.3× the strongest baseline, with decode staying within 12% of the single-turn rate across three agentic workloads. Worst-case TTFT stays below 44 s in every cell; llama.cpp hits 232 s, Ollama 179 s and KTransformers 946 s somewhere in the matrix, past the point where agent clients time out. At equal cache capacity (37% of the Qwen3.6 pool), the global LRU misses 16% of decode-time expert reads against 41% for KTransformers and 62% for llama.cpp. On an 8 GB RTX 4060 laptop the NVFP4 build serves 35B at 39.3 tok/s — above the 33 tok/s median decode speed measured for Codex in production traces. On a single RTX PRO 6000, GLM-5.2 (753B, 40B active) runs at 14.9 tok/s versus llama.cpp’s 7.3.

In this tutorial, we implement a document intelligence pipeline with deepDoctection 1.2.x that combines layout detection, table structure recognition, OCR, reading-order reconstruction, annotation linking, and structured export in a single workflow. We configure the analyzer explicitly with DocLayNet-based layout detection, Table Transformer structure recognition, and DocTR OCR, then inspect the resulting Page objects to understand how deepDoctection represents text, figures, tables, relationships, provenance, and reading order. We also extend the framework by registering custom object types and implementing our own PipelineComponent for extracting monetary and date entities while classifying documents by their tabular characteristics. Finally, we assemble a custom pipeline manually with ServiceFactory, explore filtering and service rollback, serialize processed pages, and transform document annotations into ordered JSONL chunks suitable for downstream RAG and retrieval systems.

Harvey has released Harvey Tenet, its first post-trained model, as a research preview as of today. Tenet is a Kimi K3 base post-trained with Fireworks through asynchronous reinforcement learning on long-horizon legal work. The training corpus combined synthetic data, publicly available legal data, and human expert data. Harvey states no customer data was used. Against the base K3 model, Tenet completes almost twice as many held-out tasks on Harvey’s Legal Agent Benchmark (LAB) and 20% more on LAB: Contracts, raising all-pass rate by 9 and 2 percentage points respectively. Harvey reports state-of-the-art on LAB: Contracts and second place on LAB. The gains also transferred, untrained, to Mercor’s APEX Agents and Crosby’s Redline Bench. The stated goal is twofold: build frontier legal intelligence on open-weight models, and give law firms a path to own their own specialized models. Is it deployable? Not yet, Harvey Tenet is a research preview announced on August 20, 2026. Harvey has not published weights, a model card, or an API endpoint. The base model is open-weight; Tenet itself is Harvey’s own checkpoint, and the company says the work will move “from research to production” inside Harvey’s products over time. What ships today is the recipe, not the artifact. Company tier: Enterprise only. Access runs through Harvey’s platform, which is sold to law firms, mid-sized firms, and in-house legal teams. A lab with an RL stack could reproduce the method; training used roughly 150 NVIDIA B300 GPUs over two months. Industries: Legal services, corporate in-house legal, private equity and investment banking (M&A diligence), plus regulated sectors where contract volume drives cost — insurance, financial services, healthcare, energy. Applications: M&A due diligence memos over datarooms, contract drafting, review and redlining, structured extraction across up to 10,000 documents, and precedent search over a firm’s accumulated knowledge. What the numbers say Against the base K3 model, Tenet completes almost twice as many held-out tasks on Harvey’s Legal Agent Benchmark (LAB) and 20% more on LAB: Contracts, lifting all-pass rate by 9 and 2 percentage points respectively. Harvey reports state-of-the-art on LAB: Contracts and second place on LAB, using base-model scores from Vals. The more interesting result is transfer. Tenet also improves substantially on Mercor’s APEX Agents (corporate law) and Crosby’s Redline Bench — neither seen during training — while holding performance on knowledge benchmarks including LegalBench, CUAD, MAUD, and Scale’s PRBench. Agentic training did not erode textbook legal reasoning. Cost is co-optimized rather than traded away. Open weights lower price per token; reward shaping that prefers shorter trajectories at equal quality lowers tokens consumed. Harvey reports significant quality gains at stable cost. How it was trained Training used asynchronous reinforcement learning in sandboxed legal environments built like LAB tasks: a partner-style instruction averaging about 50 words, a client matter of key and peripheral documents, and an expert rubric of atomic pass/fail criteria — roughly 50 per task, hundreds at the extreme. A single rollout can exceed 1,000 turns. Rollouts are graded by LLM-as-a-judge; ablations settled on Kimi 2.6. Reward combines the fraction of rubric criteria satisfied, a holistic count of legal issues solved, and an all-pass bonus. The policy is optimized with GSPO using a rank-64 LoRA over the full K3 network, eight task groups of eight rollouts per optimizer step, across ~1,750 environments and >10,000 rollouts per epoch. Fireworks co-built trainer and rollout deployments at the kernel level, with token-in-token-out and router replay, to keep a large MoE numerically aligned across training and inference. Three capabilities trained separately Harvey team also post-trained specialist models that Tenet can route to as tools or sub-agents: M&A diligence: On LAB: Diligence, a single task can traverse up to 80M tokens; no baseline passed more than 43.8% of criteria. With Baseten, Harvey moved to a Recursive Language Model harness where a root agent holds the dataroom in a REPL and delegates to sub-agents. A GLM-5.2 orchestrator alone reached 46.1%; post-training it in that harness via self-distillation reached 60.1%. Review Table: With Applied Compute, a post-trained GLM-5.2 improved answer quality by 3.6 points and citation quality by 12.1 points at roughly one-tenth the cost per cell, learning to abstain when a question does not apply. Firm knowledge: With Engram, a Qwen3.8-27B model studies ~100M tokens of client matters into 1M tokens of structured knowledge plus parametric memory. Criteria pass rate rose more than 15%, tokens in completed trajectories fell 58%, and cost per query dropped roughly 90% — 190.8 intelligence-per-token versus 129.3 for the best frontier configuration.

Most teams treat ‘which model’ as the important decision. The harness engineering literature keeps pointing somewhere else. In LangChain’s Terminal-Bench experiment, changing only the harness—same model throughout—moved a coding agent from roughly 30th place into the top 5. That result reframes the question. If the harness decides quality, then how you run the loop becomes an architecture decision, not a deployment detail. Paul Iusztin’s open-source course Building a Coding Agent From Scratch builds a Python agent called Decode. Published through Decoding AI, it separates three run modes. Each mode has a different latency profile. Each one therefore wants a different inference provider. One headless core, three shapes The center of the system is a headless harness with no interface of its own. Inside it runs the agent loop every harness shares: the LLM picks an action, a tool executes, the observation feeds back. Everything reads from and writes to the context window. The agent itself is small. In Decode it is a ~20-line Pydantic AI definition composing a model, tools, and an output type. In Claude Code’s leaked source, the core loop is roughly 150 lines. Everything else—memory, skills, sandbox, permissions, LSP feedback, compaction—is harness. Interfaces then plug into that core. That is where the three modes appear: Mode 1: Interactive, online A terminal UI is wired to one live session, in memory, in the same process. Events stream back through async generators as tokens arrive. The hard problem here is steering. If you type while a tool call is in flight, injecting the message immediately corrupts the turn. Decode’s answer is a steering queue plus a priority gate. Input is buffered on arrival and injected only at a safe boundary. The loop exposes two: MODEL_REQUEST, before the next model call, and WOULD_STOP, when the turn would end. Three input modes map onto that. Plain Enter steers within the turn. Alt+Enter queues a follow-up until the turn stops. Esc triggers a cooperative abort at the next boundary, clearing both queues so history stays intact. A human is reading every token. This mode is latency-bound, which is why it belongs on a low-latency hosted API. Mode 2: Remote, offline Remote mode keeps the harness headless and runs it on a server through an agent runtime. Decode uses Kitaru, ZenML’s agent runtime, deployed to GCP, with the agents themselves executing on Modal. Nobody is watching. A backlog of tickets fans out to N harnesses in parallel, each producing its own PR. Because the runtime records progress step by step, a sandbox that dies mid-task resumes from its last recorded step instead of restarting. A run that pauses for human input freezes and consumes no compute while it waits. Tools execute inside Modal Sandboxes remotely, Docker locally. The metric that matters is throughput per dollar, not time-to-first-token. Mode 3: Async, online The third shape sits between the two. A live session hands work to a job queue and returns immediately. Background workflows fan out LLM calls and post results back later. The user is online but not watching each step. The queue owns the work, so the run outlives the client that started it. This is the pattern behind Slack-triggered agents and background PR review, and it bills like batch, not like chat. The interactive explainer Why the provider changes with the mode The cost model follows the latency requirement, and the gap is large. Take 1,000 documents at 30,000 input tokens each, roughly 500 output tokens per document. At frontier API rates of $3 per million input and $15 per million output, the lesson’s arithmetic lands near $97. Prompt caching does not rescue it, because every document is a different prefix. Batched on a serverless GPU at around 3,000 tokens per second, the same work is under three hours of GPU time—roughly $13. The reverse case is just as sharp. Decode’s default test model, Qwen3.6 35B, runs on a single H200. Modal’s published pricing lists H200 SXM at $0.001261 per second, or about $4.54 per hour. Leave an interactive agent idle overnight waiting on a y confirmation, and ten idle hours add roughly $45 to the bill. That is the whole argument. Interactive work pays per token because a human is waiting. Offline and async work pays per GPU-hour because throughput is the objective and idle time is the enemy. There is a second axis: serverless versus reserved capacity. Modal’s pricing analysis reduces it to one comparison. Reservations charge the peak rate for the whole contract; serverless follows the demand curve. When the peak-to-average ratio exceeds the reservation discount, serverless is cheaper. Modal reports typical discounts of 2–5× against peak-to-average ratios of 5–10× for inference, training, and agentic development. Industry surveys it cites put reservation utilization below 30%, often under 10%. Key Takeaways Harness beats model: swapping only the harness moved an agent from ~30th to top 5 on Terminal-Bench. Interactive mode is latency-bound and steers via a queue draining at MODEL_REQUEST and WOULD_STOP boundaries. Remote and async modes are throughput-bound, so GPU-hour billing beats per-token billing at volume. 1,000 documents cost ~$97 on frontier API rates versus ~$13 of batched GPU time. Serverless wins whenever peak-to-average demand exceeds the reservation discount, typically 5–10× against 2–5×.

In this tutorial, we build an in-depth NeMo Guardrails pipeline that demonstrates how layered guardrails can control an LLM-based financial assistant across the full request lifecycle.

We also implement stateful multi-turn interactions, detailed rail activation tracing, token accounting, and a red-team-style coverage report, so we can evaluate whether the assistant responds safely, which control handles each request, and what computational cost that protection adds.

When the biotech company Insilico Medicine used its computer models to propose a promising drug for pulmonary fibrosis, it enthusiastically claimed in a press release that the molecule had been “discovered by” its generative AI platform. Insilico leads a pack of companies using AI to rapidly come up with drug ideas humans might never think of, potentially speeding the race to new cures. AI models are now able to generate atomic designs for drugs almost as easily as ChatGPT can write a thank-you note. However, when it came time to file for an all-important patent to protect that new chemical structure, the company made no mention of AI. Instead the patent names five humans, including CEO Alex Zhavoronkov, as the drug’s “inventors.” The discrepancy points to a fascinating wrinkle in intellectual-property law. No matter how fundamental an AI is to a discovery, when it comes to winning rights to an invention, it’s humans—and only humans—who can take the credit. US courts reached that conclusion after Ryan Abbott, a partner at the LA law firm Brown, Neri, Smith & Khan, brought a pro bono test case naming an AI called DABUS as an inventor of a better food container, whose intricate geometric surface lets it transfer heat well and stack easily. Because no human contributed to the design, Abbott argued that the AI should be named the inventor. The case might have raised philosophical questions, like whether AIs deserve legal rights or what the true nature is of that eureka moment that leads to a better mousetrap. But in 2022, an appeals court in Washington, DC, said these “metaphysical matters” were beside the point. Instead, it noted that US statutes describe an inventor as an “individual,” the plain meaning of which is a human being. Since machines aren’t people, they can’t be inventors. Case closed. “There needs to be a human inventor or there’s no invention and no patent,” says Sarah Korman, a patent attorney who is now chief business officer and legal officer of Isomorphic Labs, an Alphabet spinout with big ambitions for AI cures. Korman, who made her remarks at MIT Technology Review’s EmTech event last year, added that there is “no doubt” our laws will need to evolve to keep pace with AI. That’s partly because no one is denying that AIs can invent things. In the future, they may do so with less and less human intervention. As the US Patent and Trademark Office has itself acknowledged, “an AI system—like other tools—may perform acts that, if performed by a human, could constitute inventorship under our laws.” Instead, the key question going forward may actually be whether or not any human contributed enough to be named as an inventor. Abbott believes there could be legal challenges to AI-generated drugs, since one way to invalidate a patent is to show it has the wrong inventors listed. Abbott’s worry is that if US policy excludes AI-generated outputs from protection, that could put a damper on future drug development. Already, the US Copyright Office is refusing to grant copyrights to images and text generated by AI, raising concerns from organizations like the Motion Picture Association of America, whose members are using those tools.  The point of our intellectual-property laws is to encourage innovation, Abbott says. It’s right there in Article 1 of the US Constitution, which says inventors and authors need to be given exclusive rights to their ideas, for a limited time, in order “to promote the Progress of Science and the Useful Arts.” Currently, the US patent office seems to be taking a don’t-ask-don’t-tell approach to the use of AI. Under the Biden administration, the agency published guidance to help applicants determine whether and when humans would truly qualify as co-inventors of an AI discovery. But after Trump arrived in office, it reversed course. Now the patent office says AI is merely a tool, like a calculator. No need to even mention it. You can bet that pioneering AI drug companies are keeping humans in the loop, at least for now, and documenting everything carefully. At Insilico, Zhavoronkov says, human chemists still have to synthesize the drugs, create variants, and test them on animals. “That’s the person who is going to be named on the patent,” he says. “And even if you decided to completely roboticize this process, including the experiments, someone will still push the button and give the budget.” Should pushing a button count as being an inventor? Abbott says that’s a question for future legal cases. “What if I asked Claude to cure cancer, and it did?” he says. “I think it would be inappropriate to claim that I invented that.”  This article first appeared in The Checkup, MIT Technology Review’s weekly biotech newsletter.

A company that plans to beam sunlight from space to Earth on demand might unintentionally brighten the night sky for many more people than intended, according to a new study. Later this year, the US company Reflect Orbital plans to launch a test satellite called Eärendil-1 that will extend an 18-by-18-meter mirror in orbit. The goal is to test the feasibility of the company’s plans to launch up to 50,000 larger satellites, measuring 54 by 54 meters, and reflect sunlight to Earth on demand. The case for doing this remains somewhat uncertain, but Reflect Orbital has said the goal is to prolong the hours of sunlight for various uses, including solar panel charging, emergency response, and military activities. The launch, which was approved by the Federal Communications Commission in July, has been met with disbelief by astronomers and environmental groups. “This is incompatible with astronomy,” says Samantha Lawler, an astronomer at the University of Regina in Canada. “There is no way you can do this and preserve dark skies.” Miroslav Kocifaj, an astronomer at the Slovak Academy of Sciences, and his colleagues have now calculated the broader effect on the night sky. In a new paper published online and accepted for publication in the space journal Astrophysical Journal Letters, they studied the extent to which the light the satellites beamed to the ground would scatter. They found that within the beam’s target area, intended to be a circular patch five kilometers across, a single Reflect Orbital satellite would appear about 40 times brighter than the full moon in the sky. As far as 14 kilometers away from the center of the beam, the satellite would still be as bright as the full moon.  Combining the beams of 400 satellites, which Reflect Orbital eventually plans to do, would yield a light as bright as 10,000 full moons within the five-kilometer area, or 2.4% as bright as the sun. Even up to 80 kilometers away, Kocifaj and his colleagues calculated, this combined beam would be visible as “a glow above the horizon,” he says. That means the night sky would be altered for many more people than those within the area Reflect Orbital intends to illuminate. “Deploying these mirrors would be seriously damaging for astronomy and for the nighttime environment,” says Kocifaj.“ The damage extends far beyond the target area.” Olivier Hainaut, an astronomer at the European Southern Observatory in Germany, says the results of the paper are not surprising but are still useful. “These guys are really good at that kind of modeling,” he says. “They know what they’re doing.” Hainaut had previously modeled the broader effect of Reflect Orbital’s beams, finding they would brighten the sky up to 300% worldwide. This latest work gives an even more complete picture of what the impact would be. “These two papers really cover most of it,” he says. Reflect Orbital CEO Ben Nowack disagrees with the findings of Kocifaj’s paper. “Some assumptions are simply inaccurate,” he says. “The critical point is that our safeguards, including maintaining exclusion zones, take account of scattering.” He says that the company has “engaged substantively with legitimate concerns raised by astronomers, environmental researchers, and scientists,” and that their feedback has “informed our technology and operational plans.” Kocifaj says that Reflect Orbital has not provided data to back up its claims. The company “states that safeguards exist, that scattering is taken into account, and that the models are being updated, but it gives no numbers, no description of the model, no assumptions, and no data,” he says. “There is therefore nothing that can be engaged with technically. Our calculations produce concrete figures.” Reflect Orbital’s intention is to place its satellites into highly inclined orbits above Earth, almost from pole to pole. This will enable them to reflect sunlight in the hours before sunrise and after sunset, extending daylight hours in certain locations. Eventually, the company has said, it wants to place satellites high enough to provide light 24-7 to locations on Earth. In August, a group of organisations including DarkSky International and the American Bird Conservancy urged the FCC to review its approval of the Eärendil-1 satellite. As well as the impact on astronomy raised by this and future satellites, the group also highlighted potential negative consequences for aviation and wildlife. “Our primary request is straightforward: Reverse the Space Bureau’s order, and require a lawful public-interest and NEPA [National Environmental Policy Act] review,” the group said in a statement. The satellites could also pose risks to humans, according to Reflect Orbital itself. In a filing with the FCC in March, the company said that observing Eärendil-1 with a telescope larger than 12 inches —which many astronomers have access to—may be unsafe for human eyes. It added, though, that such observations are “unlikely to … result in significant injury” because the satellites are not constantly bright. Currently there is no global entity that could regulate satellites such as these, so approval falls to national regulators such as the FCC in the US. Michelle Hanlon, a space lawyer at the University of Mississippi’s School of Law, says there are “real benefits” to the plans proposed by Reflect Orbital. “It could extend the productive hours of solar facilities and provide light in remote areas or after a disaster,” she says. However, the “legal basis is less clear than the technology,” she says. The FCC “does not have authority to license or regulate the operation of the solar reflector itself.” It can only authorize the use of radio frequencies to communicate with the spacecraft. That means Reflect Orbital will need permission on a national and local level to reflect sunlight onto the ground, but if the beams spread as much as Kocifaj and his team predict, “the company could need approvals in more than one jurisdiction,” says Hanlon. “There may also be aviation-safety and cross-border questions.” The fierce debate over the satellites shows no signs of abating. “It makes me sad that astronomers are having to spend their time doing these sorts

In this tutorial, we explore AutoFigure as a practical toolkit for generating scientific figures directly from text descriptions, paper-like content, and structured methodological explanations. In this tutorial, we set up the complete AutoFigure environment, fix dependency issues such as Pillow compatibility, and prepare the required rendering tools for SVG and PNG outputs. We then build a custom reference figure, configure an API-backed generation workflow, and use AutoFigure to convert a detailed agentic document intelligence pipeline into a publication-style scientific diagram. Along the way, we also test offline SVG rendering, inspect the generated files, create a sample paper and PDF, and export the final outputs to a reusable gallery and a zip archive.

The graph contains section nodes, paragraph nodes, table nodes, figure nodes, and metadata nodes. A routing planner assigns each node to a specialized expert according to modality, complexity, and required output schema. The system uses five experts. The summarization expert produces hierarchical summaries from section-level chunks. The extraction expert fills strict JSON schemas for entities, dates, risks, financial metrics, and obligations. The table expert reconstructs exact tables and validates row-column alignment. The visual expert describes charts and diagrams. The citation expert maps every generated claim to source spans. A budget-aware orchestration layer selects model size dynamically. Simple chunks are processed by low-cost models, while complex chunks are escalated to stronger models. A verification layer then checks schema validity, citation support, numerical consistency, and table integrity. Failed checks are routed back for repair. ## Experiments We evaluate on financial filings and analyst reports using extraction accuracy, grounding precision, table reconstruction quality, and total inference cost. “”” def run(cmd, cwd=None, check=True, quiet=False): print(f”n$ {cmd}”) process = subprocess.run( cmd, shell=True, cwd=str(cwd) if cwd else None, text=True, stdout=subprocess.PIPE if quiet else None, stderr=subprocess.STDOUT if quiet else None, ) if quiet and process.stdout: print(process.stdout[-5000:]) if check and process.returncode != 0: raise RuntimeError(f”Command failed with exit code {process.returncode}: {cmd}”) return process def heading(title): print(“n” + “=” * 100) print(title) print(“=” * 100) def safe_read(path, max_chars=2500): path = Path(path) if not path.exists(): return “” text = path.read_text(encoding=”utf-8″, errors=”ignore”) return text[:max_chars] + (“n… [truncated]” if len(text) > max_chars else “”) def clear_loaded_modules(prefixes): for name in list(sys.modules): if any(name == prefix or name.startswith(prefix + “.”) for prefix in prefixes): del sys.modules[name] def get_colab_secret(names): try: from google.colab import userdata for name in names: try: value = userdata.get(name) if value: return value except Exception: pass except Exception: pass return None def collect_api_key(provider): env_candidates = [ “AUTOFIGURE_API_KEY”, “OPENROUTER_API_KEY”, “GOOGLE_API_KEY”, “GEMINI_API_KEY”, “BIANXIE_API_KEY”, ] for key_name in env_candidates: value = os.environ.get(key_name) if value: print(f”Using API key from environment variable: {key_name}”) return value secret_candidates = { “openrouter”: [“AUTOFIGURE_API_KEY”, “OPENROUTER_API_KEY”], “gemini”: [“AUTOFIGURE_API_KEY”, “GOOGLE_API_KEY”, “GEMINI_API_KEY”], “bianxie”: [“AUTOFIGURE_API_KEY”, “BIANXIE_API_KEY”], }.get(provider, [“AUTOFIGURE_API_KEY”]) value = get_colab_secret(secret_candidates) if value: print(“Using API key from Colab Secrets.”) return value value = getpass(f”Paste your {provider} API key, or press Enter to skip cloud generation: “).strip() return value We begin by importing and defining the main paths, provider settings, model configuration, and tutorial options.

The ‘neocloud’ label now covers five companies with very different business models. CoreWeave and Nebius are public companies that publish quarterly results and file reports with the SEC (CoreWeave on Form 10-Q, Nebius as a foreign private issuer on Form 6-K). Lambda and Crusoe are private and heading toward IPOs. Groq has run GroqCloud on its LPU architecture since 2024; after licensing that technology to NVIDIA in December 2025, the independent Groq refocused entirely on inference-cloud infrastructure. This article compares them on what actually matters to a buyer: published pricing, deployed and contracted power, hardware roadmap, contract structure, and independent quality ratings. TL;DR CoreWeave is the only Platinum-rated GPU cloud in SemiAnalysis ClusterMAX 2.0 and commands premium list pricing on H100, H200, and B200. Nebius is the only provider here publishing B300 on-demand pricing; Lambda publishes the lowest B200 on-demand rate. Lambda still publishes the cheapest on-demand B200 ($6.69/GPU-hr) but has no spot tier. Crusoe is the only provider here with AMD MI300X/MI355X on its rate card. Groq is now an NVIDIA Cloud Partner and plans to add NVIDIA GPU capacity alongside its LPU inference cloud.
