The vibes were strong at Code with Claude, Anthropic’s two-day event for software developers in London that kicked off on May 19, the same day as Google’s I/O in Palo Alto. (A coincidence, not a flex, Anthropic staffers assured me.) “Who here has shipped a pull request in the last week that was completely written by Claude?” Jeremy Hadfield, an engineer at Anthropic, asked from the main stage. Almost half the people in the packed room—many sitting with laptops on their knees, coding or prompting as they watched the talks—raised their hands. Pull requests are fixes or updates to existing software that are submitted for review before they go live. They are the bread and butter of software development, the chunks of code that most professional developers spend their lives writing—or did until now. “Who here has shipped a pull request that was completely written by Claude where they did not read the code at all?” Hadfield asked next. Nervous laughter. Most of the hands stayed up. It’s not news that LLM-powered tools like Anthropic’s Claude Code and OpenAI’s Codex have upended the way software gets made. Top tech companies now like to boast of how little code their developers write by hand. (“Most software at Anthropic is now written by Claude,” Hadfield said. “Claude has written most of the code in Claude Code.”) OpenAI, Google, and Microsoft make similar claims. Many others wish they could. Even so, it is striking how normal this new paradigm already seems, and how fast it has set in. This was the second year that Anthropic has put on developer events, which also run in San Francisco and Tokyo. This time last year, the company had just released Claude 4. It could code, kind of. But with Anthropic’s latest string of updates—especially Claude 4.6 and then 4.7, released in February and April—Claude Code is a tool that more and more developers seem happy to hand their work off to.    Let Claude cook.ANTHROPIC (GRAPHIC) / WILL DOUGLAS HEAVEN (PHOTO) Anthropic says its goal is to push automation as far as it will go. Instead of using AI to generate code and then having humans clean it up and fix the mistakes, it wants Claude to check and correct its own work. “The default isn’t ‘I’m going to prompt Claude’—the default is now ‘I’m going to have Claude prompt itself,’” Boris Cherny, who heads Claude Code, said in the opening keynote. If all goes well, human developers shouldn’t even see the error messages when something doesn’t work. That will all be handled by Claude, which will test and tweak, test and tweak, until everything runs as it should. As Ravi Trivedi, an engineer at Anthropic, put it in another talk: “The key principle is getting out of Claude’s way. We like to say: ‘Let it cook.’” Trivedi presented a new feature in Claude Code, announced two weeks ago, which Anthropic calls dreaming. Claude Code agents write notes to themselves, recording and saving useful information about specific tasks. When another coding agent later starts to work on the same code, it can use the notes to get up to speed faster and learn from any errors that previous agents may have made. Dreaming is a system that Claude Code uses to read through all these notes and consolidate the information they contain, spotting patterns and common issues across different tasks. In theory, dreaming should help Claude Code learn about a particular code base and get better and better at working on it. Success stories Code with Claude is an event aimed at developers. As well as product showcases and hands-on workshops from Anthropic, there were how-tos from a range of companies that had reshaped their software development teams around Claude Code, including Spotify and Delivery Hero as well as Lovable, Base44, and Monday.com—three startups vibe-coding apps that help people vibe-code apps. There were no signs of unease at Code with Claude. Everybody I met wanted in. And yet outside the conference there have been a number of reports that many coders are starting to question this bright new future. Some gripe in online forums like Reddit and Hacker News that AI coding tools are being pushed by managers chasing productivity gains, when in practice the technology makes software development harder because of all the extra code developers now have to review. “The only people I’ve heard saying that generated code is fine are those who don’t read it,” a user called pron posted on Hacker News last week.  Others claim that their coding abilities have fallen off as they hand more tasks to AI. And researchers have warned that AI tools can produce unsafe code that will make software more vulnerable to attacks.   I sat down with Claude engineering lead Katelyn Lesse and Claude product lead Angela Jiang and asked them what they made of the concerns that a sudden flood of code generated (and shipped) without proper human oversight was kicking serious security and maintenance problems down the road. “All of the old software development best practices still apply. They’ve applied this entire time,” said Lesse. “I think there are a lot of people and teams that may have lost sight of them in this moment.”  And yet as Anthropic and others push for greater automation and tools like Claude Code improve, the temptation increases to offload more and more tasks, including oversight. Lesse told me that some of the technical managers at Anthropic are exhausted by keeping up with all the code their teams now produce. “Part of things happening so much more quickly is just managing your time,” she said. “I think that right now Claude is probably as good as a midlevel engineer at writing code,” she added. You still need expert engineers to design a system and troubleshoot harder problems, she said, “But over time we want Claude to get better and better at all different types of engineering.” Jiang agreed: “I think the absolute end state we’re trying to get

Simultaneous interpretation is one of the harder problems in applied AI. You’re asking a model to translate speech before the speaker has finished a sentence. Every extra second of delay breaks the illusion of real-time communication. Alibaba’s Qwen team has been chipping away at this with each release. Their latest model, Qwen3.5-LiveTranslate-Flash, brings that latency down to 2.8 seconds and expands input language coverage to 60 languages. https://qwen.ai/blog?id=qwen3.5-livetranslate A Meaningful Jump From the Previous Release The Qwen3-LiveTranslate-Flash handled 18 input languages at roughly three seconds of latency. Qwen3.5-LiveTranslate-Flash brings that down to 2.8 seconds, expands input coverage to 60 languages, and adds speech output in 29 languages. That’s more than a 3× expansion in language coverage on the input side. For devs building multilingual products, this reduces the need for per-language model switching in most global enterprise scenarios. The latency improvement comes from a technique for processing what the team calls ‘reading units.’ Rather than waiting for a full sentence to arrive before producing output, the model decides when enough meaning has accumulated in a segment to commit to a translation. It streams output continuously while the speaker is still talking. This is the same underlying logic as semantic unit prediction but with a tighter implementation that shaves off that extra 200 milliseconds. Vision Is Now a First-Class Input Most translation systems treat audio as the only input signal. That works fine in clean studio conditions. It breaks down in a crowded conference room, a noisy trade floor, or anywhere with overlapping voices and bad acoustics. Qwen3.5-LiveTranslate-Flash takes a different approach. It analyzes visual information in parallel with audio on-screen text, physically shown objects, lip movements, and gestures. When a word is phonetically ambiguous or the audio stream degrades, the visual context fills the gap and sharpens the translation decision. This is not a minor feature. In real-world deployment, audio quality is rarely guaranteed. Having a vision channel means the model handles the messy reality of live interpretation more gracefully than audio-only systems. Voice Cloning Happens in Real Time This is the part that stands out most in the Qwen3.5 release. Standard translation systems replace the speaker’s voice with a generic synthesis voice. Qwen3.5-LiveTranslate-Flash instead clones the characteristic voice features of the original speaker during the translation itself. A single spoken sentence is enough for the model to perform this acoustic adaptation. For listeners on the receiving end, the translated output sounds like the same person speaking the target language and not a robotic substitute. In live conference interpretation, multilingual livestreams, or international customer calls, this is important. The experience feels noticeably more human than what current systems deliver. Configure Domain-Specific Keywords One persistent failure mode for translation models in professional settings is proper nouns and specialized vocabulary. A model translating a medical briefing might consistently mistranslate a drug name. A legal interpretation session breaks down over a technical statute term. Qwen3.5-LiveTranslate-Flash addresses this with dynamic keyword configuration at runtime. Developers can inject a glossary of brand names, medical terms, legal terminology, or technical vocabulary, and the model handles those terms significantly more reliably. This isn’t available in most general-purpose translation APIs and it closes a real gap for domain-specific enterprise deployments. Benchmark Performance On FLEURS and CoVoST2 — two established benchmarks for multilingual speech translation — Qwen3.5-LiveTranslate-Flash outperforms major commercial alternatives. FLEURS tests translation quality across a wide variety of language pairs under real acoustic conditions. CoVoST2 covers 21 translation directions from speech, making it a practical proxy for multilingual pipeline performance.

NVIDIA researchers have released Nemotron-Labs-Diffusion, a language model family that unifies three decoding modes in one architecture. The model supports autoregressive (AR) decoding, diffusion-based parallel decoding, and self-speculation decoding. It is available in 3B, 8B, and 14B parameter sizes. The family includes base, instruct, and vision-language variants. Sequential Decoding Limits Throughput Standard autoregressive (AR) language models generate text one token at a time, left to right. Each token depends on all previous tokens. This sequential dependency limits GPU parallelism per generation step. The result is low hardware utilization at low batch sizes — the typical setting for single-user or edge deployment. Diffusion language models (LMs) offer a different approach. Instead of generating tokens sequentially, they denoise multiple tokens in parallel per forward pass. This enables higher throughput. The tradeoff has been accuracy: diffusion LMs have consistently lagged behind AR models on benchmarks, requiring substantially more data to reach comparable performance. A key reason is that diffusion training treats all token permutations uniformly, rather than leveraging the strong left-to-right prior inherent in natural language. https://d1qx31qr3h6wln.cloudfront.net/publications/Nemotron_Diffusion_Tech_Report_v1.pdf?VersionId=db8_EMO8B.vmU26.jr7Le9pN3MqcUDNL What Is a Tri-Mode Language Model? Nemotron-Labs-Diffusion is trained on a joint AR-diffusion objective. At inference time, it operates in three modes depending on the deployment context. There are no mode-specific architectural modifications — the same weights serve all three modes. AR mode is standard left-to-right autoregressive decoding using causal attention. This mode is best suited for high-concurrency cloud serving. Diffusion mode denoises multiple tokens in parallel within a fixed-length block. The sequence is partitioned into contiguous blocks. Within each block, tokens attend bidirectionally. Across blocks, attention remains causal, so prior blocks can reuse their KV cache. A lightweight trained sampler predicts, per masked position, whether the model’s top-1 prediction at the current denoising step is correct. Positions predicted as correct are committed in that step. This allows the model to commit multiple tokens per forward pass. Self-speculation mode uses the diffusion pathway to draft candidate tokens and the AR pathway to verify them, within the same single model. No auxiliary draft model or separate prediction head is required. The diffusion pathway generates a block of k candidate tokens in parallel. The AR pathway then runs a second forward pass over those candidates using causal attention, verifying the longest contiguous prefix that matches AR predictions. Each cycle produces between 1 and k+1 verified tokens. This contrasts with Multi-Token Prediction (MTP) methods such as Eagle3, which use small auxiliary draft heads attached to an AR backbone. Training The joint training objective combines an AR next-token prediction loss and a block-wise diffusion denoising loss: ℒ(θ) = ℒ_AR(θ) + α · ℒ_diff(θ) The coefficient α is set to 0.3 across all training stages. Ablation experiments varying α from 0.1 to 1.0 show that both AR-mode and diffusion-mode accuracy peak at α = 0.3. No value in the range [0.1, 0.5] improves one mode at the expense of the other — the two objectives rise and fall together. Two-stage training first trains the model purely on the AR objective for 1 trillion tokens, building strong left-to-right linguistic priors. Stage 2 then introduces the joint objective for 300 billion additional tokens. In ablations, two-stage training contributed +5.74% average accuracy. Adding the AR loss contributed the single largest gain at +7.48%. Global loss averaging — treating all tokens across a batch equally rather than averaging per-sequence first — contributed +2.12% by reducing gradient variance from variable diffusion masking ratios. Cumulatively, the full training pipeline improved the baseline by 16.05% average accuracy. All models are initialized from pretrained Ministral3 base models, not trained from scratch. Training was performed on 256 NVIDIA H100 GPUs. Instruct models are trained via supervised fine-tuning (SFT) on 45 billion tokens on top of the base models, using the same joint AR-diffusion objective with α = 0.3. The training and inference pipeline is released through Megatron Bridge. LoRA-Enhanced Linear Self-Speculation The base diffusion-to-AR alignment in self-speculation can be improved with a LoRA adapter. This adapter is fine-tuned on the diffusion draft pathway to better align its output with the AR verifier. It targets only the o_proj layer of the attention module (rank 128, α = 512, approximately 36M trainable parameters, 0.4% of the backbone). LoRA tuning improves tokens per forward (TPF) by 14.4%, 32.5%, and 27.6% at the 3B, 8B, and 14B scales respectively, with negligible accuracy change. Speed-of-Light Analysis The research team reports a speed-of-light (SOL) analysis — a theoretical upper bound on tokens per forward pass achievable by the diffusion mode, assuming an oracle sampler that correctly identifies all positions that can be safely committed in parallel. At block length 32, the SOL acceptance rate reaches 7.60× on average, exceeding 10× on coding and multilingual tasks. Current confidence-based sampling achieves approximately 3× TPF at comparable accuracy, leaving a large gap to the SOL ceiling. Comparing against linear self-speculation: both approach similar acceptance rates (6.82× for linear self-speculation vs. 7.60× SOL). However, the real tokens per forward pass (TPF) gap is much larger — 6.02× for SOL versus 3.41× for linear self-speculation, a 76.5% difference. Linear self-speculation requires two forward passes per cycle (one diffusion draft, one AR verify) and accepts only a contiguous prefix. These two constraints cap its real TPF well below SOL, even when drafter and verifier are well aligned. https://d1qx31qr3h6wln.cloudfront.net/publications/Nemotron_Diffusion_Tech_Report_v1.pdf?VersionId=db8_EMO8B.vmU26.jr7Le9pN3MqcUDNL Benchmark Results On the 10-task instruct evaluation (HumanEval, MBPP, LiveCodeBench-CPP, GSM8K, Math500, AIME24, AIME25, GPQA, IFEval, MMLU): NLD-8B AR mode: 63.61% average accuracy, versus 62.75% for Qwen3-8B and 58.02% for Ministral3-8B-Instruct. NLD-8B diffusion mode: 63.18% average accuracy with 2.57× TPF. NLD-8B LoRA-tuned linear self-speculation: 62.81% average accuracy with 5.99× TPF. NLD-8B quadratic self-speculation: 64.04% average accuracy with 6.38× TPF. On SPEED-Bench with SGLang on an NVIDIA GB200 GPU, linear self-speculation achieves 4× higher throughput than Qwen3-8B and 3.3× speedup over the NLD-8B AR mode at concurrency 1 (3.97× with an optimized CUDA kernel). Compared to Qwen3-8B-Eagle3, linear self-speculation delivers a 2.4×, 2.3×, and 1.8× speedup at batch size 1 on GB200, RTX Pro 6000, and DGX Spark respectively. Acceptance length is the underlying

Here is the number that defines the current state of things:

The baby chicks were shifting and starting to pip—or trying to hatch. But not from an egg.  Instead, these chickens were growing inside transparent 3D-printed plastic cups at the Dallas headquarters of Colossal Biosciences. The biotech company today claimed it has developed a “fully artificial egg” as part of its effort to resurrect extinct avian species, including birds like the dodo and the giant moa. But “artificial eggshell” would probably be a better description for the invention. It’s an oval-shaped printed lattice, coated inside with a special silicone-based membrane that lets in oxygen, just as a real eggshell does.  To generate birds, Colossal took recently laid chicken eggs and carefully poured their contents into the artificial shells, where they continued growing. A window on top lets researchers peek inside.   “To see them all moving around in their artificial eggs was absolutely mind blowing,” says Andrew Pask, the company’s chief biology officer. “You really feel you can grow life outside of the womb.” Colossal was founded in 2021 with plans to use gene editing and reproductive technology to restore extinct species, including the woolly mammoth. It’s since raised more than $800 million toward what it now terms the “scalable and controllable” creation of animals. According to Pask, the egg technology could help conserve at-risk bird species. It could also play a role in a project to re-create the extinct giant moa, a flightless 12-foot-tall bird that once lived in New Zealand and laid four-liter eggs, larger than those of any living bird. But Colossal may be able build one that’s big enough. The company provided a photograph of a prototype 3D-printed egg so large that staff have started to call it the “salad spinner.” The moa went extinct after canoes carrying the ancestors of the Maori arrived on New Zealand’s South Island about 750 years ago. Archeological sites showcase the birds’ bones alongside stone cutting tools—clear evidence that they were hunted. To be clear—Colossal isn’t close to re-creating the moa. Before that could happen, scientists would need to study DNA data from old moa bones and insert thousands of genetic changes into the genome of an existing bird, something that’s still technically difficult to do—with or without an artificial egg. COLOSSAL BIOSCIENCES Some scientists also think Colossal is taking too much credit for its artificial eggshell, which it announced in a thundering YouTube video intoning that the company has solved the “impossible question of which came first, the chicken or the egg.” The video is pure Hollywood—it’s meant to be funny and exciting. But Colossal has a habit of antagonizing scientists by making false and exaggerated claims. Last year, for instance, the company said it had re-created the extinct dire wolf—a claim widely rejected by experts.  This time, Colossal’s fluffed-up assertion of having created the “first-ever shell-less incubation system” is what’s raising hackles among the small flock of scientists who’ve been working on the technology for years.  “Clearly an overstatement,” says Katsuya Obara, at the University of Tsukuba in Japan, who in 2024 hatched chickens from beneath transparent plastic film. “The technology here is essentially a modification of existing methods.” In fact, Obara notes, growing birds in artificial containers goes all the way back to 1998, when another Japanese group managed to do it with quail. What may be an advance by Colossal is the special membrane, which lets the embryo access more oxygen. Previous systems required scientists to supplement the gas—something that may not have been good for the chicks, as often some of them would fail to hatch.  The work on the artificial eggshell was carried out in Dallas by Colossal’s exogenous development team, or Exo Dev. That group is also trying to develop artificial wombs for mammals, starting with marsupials. “We’re looking at every single facet of what’s happening during a mammalian pregnancy to unpack exactly how we then go about recapitulating that,” says Pask. For that team, an artificial eggshell is a relatively quick and easy technical win. That’s because chickens are already an example of ex utero development. After an egg is laid, a small embryo sitting on top of the yolk starts growing, drawing nutrients from the yolk, the white, and even the shell., which provides calcium. (Colossal says it has to add ground-up calcium to the artificial eggs.) COLOSSAL BIOSCIENCES In order to create a moa, Colossal will have to genetically alter another type of bird, changing potentially thousands of DNA letters. But so far, chickens are the only bird species that can be genetically engineered. And that’s via a tricky process of editing stem cells that produce egg and sperm. Scientists have to add or delete DNA letters from these cells and then inject them back into an egg. The resulting bird will carry the genetic change in its gonads—and then be able to pass it on.  Pask says Colossal’s idea is that it could modify avian stem cells enough toproduce moa-like sperm or eggs. But then you might have the odd situation of a chicken laying an egg with a moa embryo inside it. “You would have chickens making moa egg and moa sperm. But it’s still a chicken egg,” he says. Helen Sang, a professor emeritus at the Roslin Institute in the United Kingdom, says she’s not sure a moa embryo could survive on the yolk of a chicken egg, given evolutionary differences. “There are significant challenges to overcome to grow an embryo of a different species in artificial eggs,” says Sang. Just one of those is the huge size discrepancy. The amount of yolk in a chicken egg would hardly be enough to support the much larger moa chick. Yet Pask says that is exactly where the artificial egg will come in handy. He says it may be possible to use a fine needle to slowly “put 50 yolks together to make that yolk mass much larger.” “The chicken egg isn’t going to be big enough to support the growth of the moa through to term, to when it

This is today’s edition of The Download, our weekday newsletter that provides a daily dose of what’s going on in the world of technology. Here’s why Elon Musk lost his suit against OpenAI Elon Musk has lost his lawsuit against OpenAI, which centered on whether the company breached its founding contract as a nonprofit. A jury found that he sued too late, meaning his claims are barred by statutes of limitations. But the verdict didn’t judge if OpenAI violated its nonprofit mission—only whether Musk brought the case in time. The dispute centers on when OpenAI began shifting toward a for-profit structure. The company argued that signs of a shift were visible as early as 2017, while Musk said he only discovered the change in 2022. Here’s a closer look at the timeline, why Musk lost, and why the fight over OpenAI’s structure may not be over. —Michelle Kim Join us later today for a subscriber-only Roundtables discussion about what happened in the courtroom and what the verdict means for OpenAI and the larger AI race.
