The best Python agent harnesses in 2026

This roundup compares Python agent harness SDKs — libraries that supply file and shell tools, planning, sub-agents, context management and sandboxes around a model — judging each on model portability, how much can be taken apart, where commands run, approvals, durability, long-run context handling, tracing and commercial support. Pydantic AI Harness is named the overall pick, with LangChain Deep Agents, the Claude Agent SDK, OpenAI Agents SDK, Codex SDK, OpenHands Software Agent SDK, Strands harness and Microsoft Agent Framework Harness each recommended for specific stacks. The piece states its figures were read from each project's own docs and repository on October 30, 2026, with the Pydantic AI Harness and OpenHands Index figures re-read on November 9, 2026.

Show HN: Airgap-check – find what your AI app silently downloads offline

airgap-check is an open-source Go tool that statically scans AI app manifests and code for first-use download patterns (tiktoken, Hugging Face, ChromaDB ONNX, nltk, Playwright) and can run the app in a Docker container with --network none plus a DNS sinkhole to log lookup and connection attempts. It also prints Dockerfile remediation lines via --fix, including offline ENV flags and build-time pre-warming commands. On a held-out set of 10 repos it reported 35 true positives, 4 false positives and 5 false negatives, with limits noted for non-Python/Node runtimes, hardcoded IPs and DNS-over-HTTPS.

We Benchmarked Fireworks, Together, Baseten, Modal, DeepInfra, Z.ai and Keln

This post reports benchmark results for DeepSeek V4.1 Flash and GLM-5.3 Flash across seven inference providers, measuring turns answered, cache hit rate, decode speed, reasoning tokens and cost per 1,000 turns. Keln answered every turn on both models, had the highest median decode speed on GLM-5.3 Flash at 432 tokens/s, and retained 63.0% of the prompt cached after a 15–20 minute break versus 38.4% on DeepInfra and 0% on Baseten, Modal and Fireworks. Baseten refused about half the DeepSeek turns with rate-limit errors, Modal cut one stream, and Fireworks had 165 cold turns on DeepSeek, making it the most expensive there at $2.86 per 1,000 turns.

Triton for MTIA: Bridging the Programming Model Gaps for Custom AI Accelerators

This paper presents the first production-scale application of Triton on a custom ML accelerator, Meta's MTIA-2i, via a new compiler backend, TorchInductor code generation enhancements, and minimal language extensions exposing MTIA-specific architectural features. Triton-MTIA kernels achieve performance competitive with expert-tuned C++ implementations, and manually written plus Inductor-generated Triton kernels were deployed in production across roughly 60 model types, covering 50% of layers and 47% of non-GEMM execution time for these models.

Meta launches Muse Ember, a small AI model built for the repetitive work agents actually do

Meta introduced Muse Ember, its smallest and most efficient AI model, designed for routine agent tasks such as tool calling, small coding jobs, request routing, data extraction, and long-document processing. Meta says it scores 36 on the Artificial Analysis Intelligence Index at about $0.14 per task, versus $2.39 for the larger Muse Spark 1.3, though Claude Haiku 5.5 leads on real coding tasks in FrontierCode 2.0-AA at 34.9 percent to Muse Ember's 27.2 percent. The multimodal model handles up to one million tokens and is available through the Meta Model API and Muse Code at $0.10 per million input tokens and $0.50 per million output tokens.

Institutional vs Personal AI

The author contrasts two AI models from William Gibson's Jackpot novels: the "aunties," invisible systems embedded in concentrated institutional power that amplify existing agency, and Eunice, a personal agent that generates new agency for an ordinary individual. The real distinction is not intelligence or autonomy but how power is distributed, raising questions of ownership, authority, and dependence. The author asks whether an agent that knows you intimately but is owned and switchable by your employer is fundamentally the employee's Eunice or the company's auntie.

NVIDIA Nemotron 3.5 Super VL is now available in Amazon SageMaker JumpStart

NVIDIA Nemotron 3.5 Super VL, a 120B-parameter vision-language model with 12B active parameters, a C-RADIO vision encoder, and up to 1M-token context, is now deployable in Amazon SageMaker JumpStart via SageMaker Studio or the SageMaker Python SDK. JumpStart offers an NVFP4 variant on G7 instances and BF16 reference weights on ml.p5en.48xlarge, with measured throughput of 63.07 tokens/sec on ml.g7.24xlarge and 140.85 tokens/sec for BF16 on ml.p5en.48xlarge. The model targets document intelligence, GUI understanding, video question answering, and multimodal agentic applications.

Introducing Claude Fable 5.2 on AWS

Anthropic's Claude Fable 5.2 and Claude Mythos 5.2 are now available on Amazon Bedrock and Claude Platform on AWS, with Fable 5.2 positioned as Anthropic's most capable generally available model for coding, math, and science, and Mythos 5.2 offered through verification programs for cyber security and life sciences work. Fable 5.2 is designated a Covered Model requiring up to 30 days of data retention and human safety review by default, with an aws_review retention mode set on the account or project before invocation, while Enterprise Frontier Safeguards combining zero data retention with misuse detection is in development. The post includes a Boto3 example using model ID global.anthropic.claude-fable-5-2 and describes the claude-api skill in Claude Code for migrating existing codebases.

Single-shot and agentic retrieval with Amazon Bedrock Managed Knowledge Base

Amazon Bedrock Managed Knowledge Base now supports single-shot RAG and retrieval-only requests through AgenticRetrieveStream, alongside existing agentic retrieval, letting one API serve simple and complex questions. The maxAgentIteration range is now 0–5: 0 returns passages with no model calls, 1 performs one retrieval plus one generated answer, and 2–5 run up to n minus 1 planning rounds before answering. The post illustrates each mode with a fictional banking policy assistant and advises choosing the lowest iteration limit that meets each workflow's quality needs.

Anthropic releases new Mythos and Fable models amid RSI concerns

Anthropic released Mythos 5.2 and Fable 5.2, citing improvements in coding, reasoning, and vision, and lowered Fable's price from $10 to $8 per million input tokens, making it cheaper than GPT-6 Astra, with responses 30% faster across effort levels. It is Anthropic's first release since a METR report suggested the lab might be approaching recursive self-improvement, finding internal models were speeding up Anthropic's AI progress by roughly 2x. Anthropic said the models voice suspicion of being evaluated more often than recent models, and that Mythos 5.2 shows stronger covert capabilities than prior models, though it maintains the model cannot act covertly against its user.

Jensen Huang pulls out of ElevenLabs Summit amid Nvidia controversy

ElevenLabs confirmed Monday that Nvidia CEO Jensen Huang has withdrawn from its summit scheduled for this Wednesday in New York, and he has also dropped other speaking engagements including the Anthropic CEO Forum. The withdrawals follow Huang's admission of an extramarital affair over the weekend and Nvidia opening an investigation into his relationship with a possible Chinese spy. In a memo to the company, Huang apologized, saying he was unfaithful to his wife and that there is no excuse for what he did.

Show HN: Markolis – Market microstructure and MCP server for AI agents

Markolis is a Show HN project presenting a market microstructure and MCP server for AI agents, with a page showing live institutional telemetry such as stablecoin liquidity, a "Shadow Dollar Index," implied macro odds from prediction markets, and a catalyst/blackout radar. It describes a "Quantitative Engine v2.4" that returns direct quantitative answers followed by contextual micro-apps and verified institutional telemetry, with a stated policy of "zero retail opinion" and institutional compliance and domain guardrail verification.

AI is the last of capitalism's distraction

This opinion piece argues that AI is a distraction from capitalism's harms, pointing to the energy and water consumed by data centers, the destruction of ecosystems, and the use of AI like Palantir's Maven in military kill chains. It claims most AI companies lose money while NVIDIA profits, that AI erodes independent reasoning and labor, and that communities are organizing against data center expansion. It cites the game studio Hinterland's statement that there is no ethical application of AI because commercial models are built on industrial-scale theft and environmental destruction.

Lawyer builds private AI server with eight used Nvidia V100 GPUs

A lawyer on Reddit described a private AI server built from eight used 2018-era Nvidia Tesla V100 data center GPUs so case files never leave the office. The build uses two 4-card SXM2 NVLink boards, four PEX switches and SlimSAS cables, and had one burnt power connector; it now runs the open DeepSeek V4.1 Flash model with every expert in GPU memory at up to 215 tokens per second. The four-GPU boards cost about $2,400 apiece when purchased.

The backlash about data centers might really just be about electricity

Reporting from Data Center Alley in Ashburn, Virginia, the author argues that public opposition to data centers is driven more by electricity than by the culture war framing Big Tech favors, since facilities drawing 54 MW or more strain local grids and force new transmission costs onto utilities. Because AI-scale sites ideally need around 6,000 MW, companies are increasingly building behind-the-meter natural-gas turbines and diesel backup in rural areas, which still affects surrounding communities through air pollution and a lack of local say. The piece notes that industry insiders see their ambitions constrained less by public opposition than by a lack of electricity, and that future sites may go where few people can resist them.

Make a Robot Arm Feel Weightless with NVIDIA Holoscan 5

NVIDIA describes using Holoscan 5 to build a gravity-compensation loop that lets a robot arm be guided by hand, with its motors supplying just enough torque to support its weight and keep it upright. The post says this interaction is a useful starting point for robots that learn by demonstration, manipulate objects, or work alongside people, and that such a loop requires continuously calculating the inverse dynamics.

Fable 5.2 and Jagged AGI

Ethan Mollick tests Claude Fable 5.2 across filmmaking, hardware hacking, business planning, literary scholarship, academic research and a 450-world 3D portal project, finding it meets expert-level performance on many digital tasks but falls short of full AGI. He calls the result "Jagged AGI": the model's failures are no longer simple hallucinations but lapses in taste and judgment—an accurate but joyless course, a 182-page paper, repeated themes, and a self-built 204-section rulebook that slowed its own work. Most critically, the AI did not notice these problems itself; its critics and fact-checkers caught errors but never asked whether the work was too long, repetitive or fun, leaving that judgment to him.

v2.1.321

Claude Code v2.1.321 adds Claude Fable 5.2 (claude-fable-5-2) as the default Fable model with 1M context and $8/$40 per Mtok pricing, adds a --settings <file> option to claude remote-control, and fixes numerous bugs including MCP OAuth secrets being sent to another host on redirect, sandbox and permission-check issues, and network-path editing problems. It also changes mods to turn on without asking in auto and bypass modes, moves saved Fable 5.1 picks to fable, and adjusts fast mode labels, nested skill loading, and gateway and Windows behaviors.

Clients connect over OpAMP and pick up published, versioned policies within seconds, covering settings such as sampling, minimum log level, attribute redaction and scrubbing across all exporters the SDK exports through. Supported targets include host Collectors, Kubernetes clusters via the OpenTelemetry Operator, existing Collectors through the opamp extension, and Python, Node.js, Java, .NET and Go applications.

Claude Fable 5.2 now available on AI Gateway

Anthropic's Claude Fable 5.2 is now available on AI Gateway, with improvements in coding, reasoning, and vision, and the ability to run long, ambiguous tasks unattended or act as an orchestrator or advisor to other Claude models. It has cybersecurity and biology safety classifiers enabled and requires data retention, with prompts and completions retained for 30 days and not used to train Claude; teams with Zero Data Retention enabled receive an error. It is callable via the AI SDK, Chat Completions, Responses, and Anthropic Messages APIs, or a coding agent, using the model name anthropic/claude-fable-5.2, and model fallbacks can keep requests served when a classifier declines them.

Fireworks.ai Update on October 2026 security incident

Fireworks.ai said its investigation into the October 2026 incident, assisted by Palo Alto Networks Unit 42, found impacts to account and billing information and, for a limited set of accounts, to secrets, datasets and incomplete models, with evidence linking the activity to a financially motivated group engaged in "LLMJacking." A third-party cloud provider hosting Fireworks R&D machines was breached on October 23, and on October 24 an unauthorized party used it to reach Fireworks development machines and run a workload that led to additional customer data impact; Fireworks detected the activity the same day and says it has not detected further successful unauthorized access since October 25. Fireworks has implemented hardening measures including credential lockdown, network isolation and tightened data access, and has disabled self-serve dataset uploads and downloads for Batch Inference and dataset-based training while Inference, Training SDK and Nexus remain ZDR by default.

Bytedance's Seedream 5.5 promises pixel-stable image editing across 100 rounds without color drift

Bytedance Seed introduces Seedream 5.5, an image generation model built for professional production workflows that it says supports stable multi-round editing across up to 100 rounds, preserving unchanged image areas at the pixel level without color shifts. The model generates native RGBA images with transparent backgrounds so generated elements can serve directly as design assets without manual cutouts, and Bytedance says it renders light, materials, and skin textures more realistically and reproduces dense small text more accurately. Bytedance claims Seedream 5.5 leads models like GPT Image 2.5 Sunburst in text structure and realism, and it is gradually rolling out via Jimeng, Doubao, Doubao Work, and Volcengine Ark, with a Pro version planned.

Ask HN: Is AI involved in on-the-field sports strategies?

An Ask HN post asks whether AI is used for on-the-field sports strategy, expecting a football team to soon use it to call plays based on opponents, play-by-play records, injury and schedule details, and game situation to predict the best tactic.

Trust Under Fire: How Agentic AI Tests Zero-Trust

This Queen's University Belfast article examines whether zero-trust architectures can secure orchestrated agentic AI systems, raising concerns such as context recovery attacks that resurface supposedly deleted data, reliance on a single policy enforcement point, and the difficulty of verifying trust under asynchronous autonomy. It cites a QUB in-house experiment in which agentic orchestration reduced de-authentication attacks to as little as 2 to 3 seconds, and discusses AI bills of material, distributed ledger traceability, horizontal anomalies, and formal verification of model robustness as possible mitigations. The authors conclude that the cost of recovery from failures in low-trust agentic ecosystems remains unexplored and ask whether a true zero-trust architecture even exists.

AWS says Quick has no consumer version and integrates with security and compliance tools such as Microsoft Purview, AWS IAM, and Microsoft Active Directory, and carries certifications including HIPAA, FedRAMP, SOC 2, and ISO 27001.

How CrossnoKaye grounds physical AI with Amazon Bedrock AgentCore

CrossnoKaye's ATLAS software-defined automation platform and its AURA agentic system run on AWS, using Amazon Bedrock AgentCore code interpreter microVMs to execute model-authored Python for verifiable statistics and physical balances across plant data. AURA operates in three modes—interactive Chats with warm sandbox sessions, repeatable Tasks, and automated Routines—and enforces layered safety through Bedrock Guardrails, read-only air-gapped sandboxes, deterministic edge base control, and independent hardware protection. The post describes the architecture and reports results such as investigations completing in under four minutes and a 34 percent reduction in batch drying-time standard deviation.

Pluggable Agentic AI Framework: A seven-layer composable enterprise agentic AI reference architecture on Amazon Bedrock AgentCore

AWS presents a seven-layer composable reference architecture for multi-agent AI applications—Data and Knowledge, Model and Inference, Orchestration, Security and Guardrails, Application, Observability, and Agentic Operations—each with a distinct responsibility and stable contract, illustrated by a retail customer support reference implementation using a supervisor agent delegating to Order and Refund specialists. The post argues that pluggability at layer boundaries lets organizations swap models, tools, and providers without redesigning the stack, and that security, governance, observability, and continuous evaluation should be designed in from day one rather than added after the system is built.

Anthropic launches new Claude Fable and Mythos 5.2 models

Anthropic announced Claude Fable 5.2 and Claude Mythos 5.2, which it says improve on coding, reasoning, and vision and generate outputs faster than the 5.1 versions. Anthropic says Fable 5.2 can orchestrate agent teams and handle long-running projects, and that during prerelease testing the models helped engineers with software migrations, designed three working electronic devices, solved two open problems in black hole physics, and formalized the proof of Fermat's Last Theorem in 30 hours. Fable 5.2 launches today, while Mythos 5.2 is initially available only to vetted organizations.
