Issue 2: Muse Spark Open, Granite Switch 4.1, and a page for every job

Open models

• Muse Spark Open. Meta released an open-weight version of Muse Spark under its own Muse Model License, which requires a "Built with Muse Spark Open" credit and does not call itself open source. Downloads require accepting the license and an access form.
• Granite Switch 4.1. IBM published 8b and 30b models under Apache 2.0 that serve chat, decisions, safety detection, and English speech-to-text from one endpoint.
• LFM2.5-24B-A2B. Liquid AI released open weights for a mixture-of-experts reasoning model built for on-device agents, the last model in its LFM2.5 family.
• Encoders and decision models. Meta published MetaEncoder-30B, a gated Apache 2.0 multimodal encoder, and Cloudflare released Clef-omni, an Apache 2.0 decision model that also accepts audio and video.
• HiRO-ACEv2. Ai2 released an updated climate emulator and a 3 km downscaling model for research and educational use under Apache 2.0.

Tool releases

• Open WebUI 0.12.0: Realtime voice calls and authenticator-app sign-in.
• DSPy 3.4.1: GEPA's structured InstructionProposer is now the default, so results can differ from 3.4.0.
• OpenHands 1.27.0: OpenCode and Pi as built-in ACP agents.
• Unsloth: browser use that asks before signing in, posting, or buying, and text-diffusion LLM training.
• ONNX Runtime CUDA Plugin EP 0.3.0: sparse attention and INT2 QMoE support.
• Prime Agent: rewritten in Rust, with Windows support in beta.

USASI has not tested any of these releases.

Hosted models and policy

• Gemini 4 Argon is available on the paid Gemini API tier and to Google AI Pro and Ultra subscribers. Google's posts do not mention a release of weights.
• Meta announced Muse Wonder and Muse Wonder Full through its Model API and Muse Code, with no license or weights named.
• Anthropic gave a METR team employee-like access for risk assessments that METR will publish. Anthropic says it cannot veto publication, only require narrow redactions. The post does not include METR's assessments.
• Also from Anthropic: election safeguards for the 2026 midterms, a Singapore office and an MOU with Singapore's digital ministry, and dynamic workflows in Claude Managed Agents, in beta.
• A White House fact sheet names eleven industry partners in the Genesis Mission Consortium.

Companies and infrastructure

• Character.AI began a voluntary Chapter 11 process to pursue a court-supervised sale.
• The SEC declared the Agility Robotics and Churchill Capital Corp XI Form S-4 effective; shareholders vote November 2, and the deal has not closed.
• The Deno team is joining Cloudflare; Deno says the runtime stays open source.
• NVIDIA contributed Vera Rubin rack designs to the Open Compute Project and, with Cisco, announced plans for USFP, a pluggable optics form factor with an open specification.
• Scale AI released DistressBench, a benchmark of crisis support in language models.

New on the site

• People: a directory with a page for every profile of the founders, engineers, researchers, and open-source maintainers connected to the catalog, each from primary sources and checked by a separate fact-checking pass. Linus Torvalds is among the newest.
• Jobs: a shareable page for every employer, linked from its organization page, and a page for every current listing with the employer's description and a link to apply. Search now understands abbreviations like ML, SWE, and PM, and listings refresh twice a day.
• The State of American AI: a monthly report computed from the catalog and the Jobs data. The October 2026 edition is the first.
• Reference: a page for every document in the U.S. AI policy tracker, and local AI by memory pages listing documented setups that fit 8 to 24 GB of graphics memory or an Apple silicon Mac.
• Also new: People Behind Big SI, AI explained for kids, search from any page, RSS feeds for every organization and model, and a badge for listed projects.
