TL;DR

The Pentagon says it will finish removing Anthropic's products from GenAI.mil by month's end, weeks after a judge called the original blacklist unlawful, while ChatGPT Mil and Grok for Government join the portal alongside Gemini. DeepSeek open-sourced its first multimodal model under MIT, and Meta graduated Muse Code out of beta with a TypeScript SDK.

Act on this

  • If you sell to or build for the Pentagon, plan around ChatGPT Mil, Grok for Government or Gemini. Claude is being removed from GenAI.mil by September's end. TechCrunch #
  • Running GLM-5.3-Flash locally through llama.cpp mainline will fail. Three competing PRs remain unmerged; use Unsloth's fork branch instead until one lands. PR #27752 #

Signals

New agent tooling is shipping harness-agnostic by default, not built around one vendor's CLI  #

Hamel Husain's evals-skills shipped Codex plugin packaging August 31, keeping installation "agent-neutral." Shreya Shankar's new DocWriter, built through August with CMU and UC Berkeley, connects Claude, Codex, Cursor or Pi as the drafting agent. DeepSeek Harness v0.1.2-alpha (August 27 and 30) runs Claude Code and Codex as installable subagents inside its own orchestration. All three demonstrated, not announced.

Beyond Husain, Shankar, Hashimoto and Steinberger, most of the roster shipped code this week rather than argued claims. A quiet week for commentary.

WATCHPentagon adds ChatGPT and Grok to GenAI.mil, plans to finish removing Claude by month's end #

ChatGPT Mil and xAI's Grok for Government joined Google Gemini for 3 million DoD personnel, 1.7 million already onboarded. Pentagon CTO Emil Michael says Anthropic's products will be fully gone by the end of September, weeks after a judge called the ban unlawful. TechCrunch

SHIPDeepSeek open-sources its first multimodal model  #

V4-Flash-Vision-Exp shipped on Hugging Face under an MIT license August 31, ten days after the same weights went live on DeepSeek's API. DeepSeek says it beats the text-only V4-Flash on chart-reading and agentic benchmarks; the company calls its own eval set narrow. Hugging Face

SHIPMeta graduates Muse Code out of beta with an SDK and subscriptions  #

August 31: inter-session messaging, workflow orchestration for parallel subagents, and a TypeScript SDK in developer preview that talks to a local muse host with no server or network involved. Three subscription tiers now undercut pay-as-you-go Meta Model API pricing. Meta

WATCHRunway previews Solaris, an interface generated frame by frame as video #

Clicks and typed input become inputs to the next generated frame, with no code involved. Built on Runway's Gen-4.5 video model. Early-access request only; no public pricing, API, or general availability yet. Runway

ACTGLM-5.3-Flash still has no merged llama.cpp support  #

Three competing pull requests have sat open since August 26; the author of one flags that numerical validation against the original weights was never finished. Unsloth's own fork branch is the only working local path for now. llama.cpp

The long view

Governance and law. On August 28, a federal judge called the Pentagon's Anthropic blacklist unlawful retaliation and unblocked federal procurement. Days later, at a Breitbart event, Pentagon CTO Emil Michael said the department will finish removing Anthropic's products by September's end anyway, adding ChatGPT Mil and Grok for Government to GenAI.mil alongside Gemini. Claude stays off. A favorable ruling did not restore access. If this holds, expect Anthropic's appeal to target the removal itself, not just the original designation, since the injunction alone has not moved the Pentagon.
