In this tutorial, we implement how to run the Bonsai 1-bit large language model efficiently using GPU acceleration and PrismML’s optimized GGUF deployment stack. We set up the environment, install the required dependencies, and download the prebuilt llama.cpp binaries, and load the Bonsai-1.7B model for fast inference on CUDA. As we progress, we examine how 1-bit quantization works under the hood, why the Q1_0_g128 format is so memory-efficient, and how this makes Bonsai practical for lightweight yet capable language model deployment. We also test core inference, benchmarking, multi-turn chat, structured JSON generation, code generation, OpenAI-compatible server mode, and a small retrieval-augmented generation workflow, giving us a complete, hands-on view of how Bonsai operates in real-world use.

In this tutorial, we explore property-based testing using Hypothesis and build a rigorous testing pipeline that goes far beyond traditional unit testing. We implement invariants, differential testing, metamorphic testing, targeted exploration, and stateful testing to validate both functional correctness and behavioral guarantees of our systems. Instead of manually crafting edge cases, we let Hypothesis generate structured inputs, shrink failures to minimal counterexamples, and systematically uncover hidden bugs. Also, we demonstrate how modern testing practices can be integrated directly into experimental and research-driven workflows.

Quantum computing has spent years living in the future tense. Hardware has improved, research has compounded, and venture dollars have followed — but the gap between a quantum processor running in a lab and one running a real-world application remains stubbornly wide. NVIDIA moved to close that gap with the launch of NVIDIA Ising, the world’s first family of open quantum AI models specifically designed to help researchers and enterprises build quantum processors capable of running useful applications. Here’s the core problem Ising is designed to solve: quantum computers are extraordinarily sensitive. Their fundamental unit of computation, the qubit, is so easily disturbed by environmental noise that errors accumulate rapidly during computation. Before you can run anything meaningful on a quantum processor, two things have to work well — calibration (making sure the hardware is tuned and operating correctly) and error correction (detecting and fixing errors as they occur in real time). Both of these have historically been manual, slow, and difficult to scale. NVIDIA is betting that AI can automate both. What the Ising Model Family Actually Includes NVIDIA Ising includes two distinct components: Ising Calibration and Ising Decoding. Ising Calibration is a vision language model — a model architecture familiar to anyone who has worked with multimodal AI — that is designed to rapidly interpret and react to measurements from quantum processors. Think of it as an AI agent that continuously watches diagnostic readouts from quantum hardware and autonomously adjusts the system to keep it running optimally. This enables AI agents to automate continuous calibration, reducing the time needed from days to hours. That’s not a minor speedup — in quantum hardware development, days of calibration time between experiments is a major bottleneck. Ising Decoding comes in two variants of a 3D convolutional neural network (3D CNN) model, each optimized for different trade-offs: one tuned for speed and the other tuned for accuracy. These models perform real-time decoding for quantum error correction. If you’ve worked with signal processing or sequence modeling, error correction decoding is conceptually similar — you’re trying to infer what the ‘correct’ state of the system should be, given noisy observations. Ising Decoding models are up to 2.5x faster and 3x more accurate than pyMatching, the current open-source industry standard. The Ecosystem Is Already Moving Ising Calibration is already in use by Atom Computing, Academia Sinica, EeroQ, Conductor Quantum, Fermi National Accelerator Laboratory, Harvard John A. Paulson School of Engineering and Applied Sciences, Infleqtion, IonQ, IQM Quantum Computers, Lawrence Berkeley National Laboratory’s Advanced Quantum Testbed, Q-CTRL, and the U.K. National Physical Laboratory. Ising Decoding is being deployed by Cornell University, EdenCode, Infleqtion, IQM Quantum Computers, Quantum Elements, Sandia National Laboratories, SEEQC, University of California San Diego, UC Santa Barbara, University of Chicago, University of Southern California, and Yonsei University. That’s a remarkably broad day-one adoption spanning national labs, Ivy League institutions, and commercial quantum hardware companies across multiple qubit modalities. How It Fits Into NVIDIA’s Quantum Stack NVIDIA Ising complements the NVIDIA CUDA-Q software platform for hybrid quantum-classical computing and integrates with the NVIDIA NVQLink QPU-GPU hardware interconnect for real-time control and quantum error correction. CUDA-Q is NVIDIA’s broader programming model for hybrid quantum-classical workflows — if you’ve written CUDA kernels for GPU acceleration, CUDA-Q follows a similar philosophy of tightly coupling classical and accelerated compute. NVQLink is the hardware bridge that lets GPUs communicate with quantum processing units (QPUs) at the latency required for real-time error correction. Key Takeaways NVIDIA Ising is the world’s first family of open quantum AI models, purpose-built to solve the two hardest engineering problems blocking practical quantum computing — calibration and error correction — using AI instead of slow, manual processes. Ising Calibration uses a vision language model to autonomously tune quantum processors, reducing the time required for continuous calibration from days to hours by enabling AI agents to interpret and react to hardware measurements in real time. Ising Decoding uses a 3D convolutional neural network (3D CNN) to perform real-time quantum error correction, delivering up to 2.5x faster performance and 3x higher accuracy compared to pyMatching. Adoption is already broad and diverse on day one, with leading institutions including Fermi National Accelerator Laboratory, Harvard, Lawrence Berkeley National Laboratory’s Advanced Quantum Testbed, IQM Quantum Computers, Sandia National Laboratories, and over a dozen universities and enterprises deploying Ising Calibration and Ising Decoding across multiple qubit modalities. Ising integrates directly into NVIDIA’s full quantum-classical software and hardware stack, complementing the NVIDIA CUDA-Q platform for hybrid quantum-classical computing and the NVIDIA NVQLink QPU-GPU hardware interconnect, with models available on GitHub, Hugging Face, and build.nvidia.com and fine-tunable via NVIDIA NIM microservices.

In this tutorial, we explore how to run OpenAI’s open-weight GPT-OSS models in Google Colab with a strong focus on their technical behavior, deployment requirements, and practical inference workflows. We begin by setting up the exact dependencies needed for Transformers-based execution, verifying GPU availability, and loading openai/gpt-oss-20b with the correct configuration using native MXFP4 quantization, torch.bfloat16 activations. As we move through the tutorial, we work directly with core capabilities such as structured generation, streaming, multi-turn dialogue handling, tool execution patterns, and batch inference, while keeping in mind how open-weight models differ from closed-hosted APIs in terms of transparency, controllability, memory constraints, and local execution trade-offs. Also, we treat GPT-OSS not just as a chatbot, but as a technically inspectable open-weight LLM stack that we can configure, prompt, and extend inside a reproducible workflow.

Table of contents What Is AI Red Teaming? Top 19 AI Red Teaming Tools (2026) Conclusion What Is AI Red Teaming? AI Red Teaming is the process of systematically testing artificial intelligence systems—especially generative AI and machine learning models—against adversarial attacks and security stress scenarios. Red teaming goes beyond classic penetration testing; while penetration testing targets known software flaws, red teaming probes for unknown AI-specific vulnerabilities, unforeseen risks, and emergent behaviors. The process adopts the mindset of a malicious adversary, simulating attacks such as prompt injection, data poisoning, jailbreaking, model evasion, bias exploitation, and data leakage. This ensures AI models are not only robust against traditional threats, but also resilient to novel misuse scenarios unique to current AI systems. Key Features & Benefits Threat Modeling: Identify and simulate all potential attack scenarios—from prompt injection to adversarial manipulation and data exfiltration. Realistic Adversarial Behavior: Emulates actual attacker techniques using both manual and automated tools, beyond what is covered in penetration testing. Vulnerability Discovery: Uncovers risks such as bias, fairness gaps, privacy exposure, and reliability failures that may not emerge in pre-release testing. Regulatory Compliance: Supports compliance requirements (EU AI Act, NIST RMF, US Executive Orders) increasingly mandating red teaming for high-risk AI deployments. Continuous Security Validation: Integrates into CI/CD pipelines, enabling ongoing risk assessment and resilience improvement. Red teaming can be carried out by internal security teams, specialized third parties, or platforms built solely for adversarial testing of AI systems.

In this tutorial, we explore how to build a fully functional background task processing system using Huey directly, without relying on Redis. We configure a SQLite-backed Huey instance, start a real consumer in the notebook, and implement advanced task patterns, including retries, priorities, scheduling, pipelines, locking, and monitoring via signals. As we move step by step, we demonstrate how we can simulate production-grade asynchronous job handling while keeping everything self-contained and easy to run in a cloud notebook environment. Copy CodeCopiedUse a different Browser !pip -q install -U huey import os import time import json import random import threading from datetime import datetime from huey import SqliteHuey, crontab from huey.constants import WORKER_THREAD DB_PATH = “/content/huey_demo.db” if os.path.exists(DB_PATH): os.remove(DB_PATH) huey = SqliteHuey( name=”colab-huey”, filename=DB_PATH, results=True, store_none=False, utc=True, ) print(“Huey backend:”, type(huey).__name__) print(“SQLite DB at:”, DB_PATH) We install Huey and configure a SQLite-backed instance. We initialize the database file and ensure a clean environment before starting execution. By doing this, we establish a lightweight yet production-style task queue setup without external dependencies. Copy CodeCopiedUse a different Browser EVENT_LOG = [] @huey.signal() def _log_all_signals(signal, task, exc=None): EVENT_LOG.append({ “ts”: datetime.utcnow().isoformat() + “Z”, “signal”: str(signal), “task”: getattr(task, “name”, None), “id”: getattr(task, “id”, None), “args”: getattr(task, “args”, None), “kwargs”: getattr(task, “kwargs”, None), “exc”: repr(exc) if exc else None, }) def print_latest_events(n=10): print(“n— Latest Huey events —“) for row in EVENT_LOG[-n:]: print(json.dumps(row, indent=2)) We implement a signal handler to capture and store task lifecycle events in a structured log. We track execution details, including task IDs, arguments, and exceptions, to improve observability. Through this mechanism, we build real-time monitoring into our asynchronous system. Copy CodeCopiedUse a different Browser @huey.task(priority=50) def quick_add(a, b): return a + b @huey.task(priority=10) def slow_io(seconds=1.0): time.sleep(seconds) return f”slept={seconds}” @huey.task(retries=3, retry_delay=1, priority=100) def flaky_network_call(p_fail=0.6): if random.random() < p_fail: raise RuntimeError(“Transient failure (simulated)”) return “OK” @huey.task(context=True, priority=60) def cpu_pi_estimate(samples=200_000, task=None): inside = 0 rnd = random.random for _ in range(samples): x, y = rnd(), rnd() if x*x + y*y <= 1.0: inside += 1 est = 4.0 * inside / samples return {“task_id”: task.id if task else None, “pi_estimate”: est, “samples”: samples} We define multiple tasks with priorities, retry configurations, and contextual awareness. We simulate different workloads, including simple arithmetic, I/O delay, transient failures, and CPU-bound computation. By doing this, we demonstrate how Huey handles reliability, execution order, and task metadata. Copy CodeCopiedUse a different Browser @huey.lock_task(“demo:daily-sync”) @huey.task() def locked_sync_job(tag=”sync”): time.sleep(1.0) return f”locked-job-done:{tag}:{datetime.utcnow().isoformat()}Z” @huey.task() def fetch_number(seed=7): random.seed(seed) return random.randint(1, 100) @huey.task() def transform_number(x, scale=3): return x * scale @huey.task() def store_result(x): return {“stored_value”: x, “stored_at”: datetime.utcnow().isoformat() + “Z”} We introduce locking to prevent concurrent execution of critical jobs. We also define tasks that will later be chained together using pipelines to form structured workflows. Through this design, we model realistic background processing patterns that require sequencing and concurrency control. Copy CodeCopiedUse a different Browser TICK = {“count”: 0} @huey.task() def heartbeat(): TICK[“count”] += 1 print(f”[heartbeat] tick={TICK[‘count’]} utc={datetime.utcnow().isoformat()}Z”) @huey.periodic_task(crontab(minute=”*”)) def heartbeat_minutely(): heartbeat() _TIMER_STATE = {“running”: False, “timer”: None} def start_seconds_heartbeat(interval_sec=15): _TIMER_STATE[“running”] = True def _tick(): if not _TIMER_STATE[“running”]: return huey.enqueue(heartbeat.s()) t = threading.Timer(interval_sec, _tick) _TIMER_STATE[“timer”] = t t.start() _tick() def stop_seconds_heartbeat(): _TIMER_STATE[“running”] = False t = _TIMER_STATE.get(“timer”) if t is not None: try: t.cancel() except Exception: pass _TIMER_STATE[“timer”] = None We define heartbeat behavior and configure minute-level periodic execution using Huey’s crontab scheduling. We also implement a timer-based mechanism to simulate sub-minute execution intervals for demonstration purposes. With this setup, we create visible recurring background activity within the notebook. Copy CodeCopiedUse a different Browser consumer = huey.create_consumer( workers=4, worker_type=WORKER_THREAD, periodic=True, initial_delay=0.1, backoff=1.15, max_delay=2.0, scheduler_interval=1, check_worker_health=True, health_check_interval=10, flush_locks=False, ) consumer_thread = threading.Thread(target=consumer.run, daemon=True) consumer_thread.start() print(“Consumer started (threaded).”) print(“nEnqueue basics…”) r1 = quick_add(10, 32) r2 = slow_io(0.75) print(“quick_add result:”, r1(blocking=True, timeout=5)) print(“slow_io result:”, r2(blocking=True, timeout=5)) print(“nRetries + priority demo (flaky task)…”) rf = flaky_network_call(p_fail=0.7) try: print(“flaky_network_call result:”, rf(blocking=True, timeout=10)) except Exception as e: print(“flaky_network_call failed even after retries:”, repr(e)) print(“nContext task (task id inside payload)…”) rp = cpu_pi_estimate(samples=150_000) print(“pi payload:”, rp(blocking=True, timeout=20)) print(“nLocks demo: enqueue multiple locked jobs quickly (should serialize)…”) locked_results = [locked_sync_job(tag=f”run{i}”) for i in range(3)] print([res(blocking=True, timeout=10) for res in locked_results]) print(“nScheduling demo: run slow_io in ~3 seconds…”) rs = slow_io.schedule(args=(0.25,), delay=3) print(“scheduled handle:”, rs) print(“scheduled slow_io result:”, rs(blocking=True, timeout=10)) print(“nRevoke demo: schedule a task in 5s then revoke before it runs…”) rv = slow_io.schedule(args=(0.1,), delay=5) rv.revoke() time.sleep(6) try: out = rv(blocking=False) print(“revoked task output:”, out) except Exception as e: print(“revoked task did not produce result (expected):”, type(e).__name__, str(e)[:120]) print(“nPipeline demo…”) pipeline = ( fetch_number.s(123) .then(transform_number, 5) .then(store_result) ) pipe_res = huey.enqueue(pipeline) print(“pipeline final result:”, pipe_res(blocking=True, timeout=10)) print(“nStarting 15-second heartbeat demo for ~40 seconds…”) start_seconds_heartbeat(interval_sec=15) time.sleep(40) stop_seconds_heartbeat() print(“Stopped 15-second heartbeat demo.”) print_latest_events(12) print(“nStopping consumer gracefully…”) consumer.stop(graceful=True) consumer_thread.join(timeout=5) print(“Consumer stopped.”) We start a threaded consumer inside the notebook to process tasks asynchronously. We enqueue tasks, test retries, demonstrate scheduling and revocation, execute pipelines, and observe logged signals. Finally, we gracefully shut down the consumer to ensure clean resource management and controlled system termination. In conclusion, we designed and executed an advanced asynchronous task system using Huey with a SQLite backend and an in-notebook consumer. We implemented retries, task prioritization, future scheduling, revocation, locking mechanisms, task chaining through pipelines, and periodic behavior simulation, all within a Colab-friendly setup. Through this approach, we gained a clear understanding of how to use Huey to manage background workloads efficiently and extend this architecture to real-world production deployments.
