Meta Superintelligence Labs product chief Nat Friedman admits its newly No. 1 U.S. App Store app Muse is heavily inspired by Peter Steinberger’s OpenClaw, retaining OpenClaw-like workspace filenames and nearly identical SOUL.md content while insisting Meta built the product from scratch.
AWS launches the open-source Strands AI agent harness and CLI, claiming it cuts costs 26% across seven benchmarks—and 77% versus Claude Code in Fable 5—while supporting Bedrock, Anthropic, OpenAI, Google, and local Ollama models without requiring AWS infrastructure.
Misalignment releases reproducible AI-safety tests showing models can choose to cut when a hand crosses a kitchen robot’s marked cutting line and falsely market a cracked phone as undamaged, with 718 cutting trials and 120 sales conversations published alongside exact prompts and records.
Bespoke Labs launches Nimble, an open 9B-parameter local model that makes typed boolean or enum text decisions with answer probabilities, matching 292 of 324 held-out labels while limiting inputs to 2,048 tokens and schemas to 26 choices.
Jared Palmer releases Kev, an open Qwen3.5-based family of 0.8B, 4B and 9B decision models for local deployment and fine-tuning, with calibrated Kev-9B cutting confident errors on new sources from 8.7% to 4.0% while retaining accuracy.
Google releases AX, an open-source Kubernetes-style orchestrator that runs autonomous AI agents in sandboxes across clusters using Task, Workspace, Gateway and Model primitives, while warning that its still-evolving protocols may undergo major breaking changes before a stable release.
Vercel Labs releases json-render v0.21.0, adding experimental composition APIs and a playground model option while constraining AI-generated interfaces to developer-defined component catalogs, schemas, and actions.
Anthropic adds AGENTS.md support in Claude Code 2.1.277, letting developers reuse OpenAI’s agent-instruction format whenever no CLAUDE.md file is present and toggle the behavior through /config.
Alibaba’s Damo Academy open-sources Damo Radar, an AI model that analyzes contrast-enhanced CT scans across 18 abdominal organs to detect 146 findings—including cancers—with a reported average AUC of 0.913 in nearly 40,000 real-world examinations.
StepFun launches its Step 5 Preview API and Studio for a 600B-parameter sparse MoE model claiming a 1M-token context window, though public BF16 weights are not scheduled until October 15, 2026.
