The one thing

01

Codex 0.154 puts GPT-6 Astra in the picker; Claude Code pins to 2.1.267; MAI-Code-1-Flash leaves Copilot today.

openai/codex rust-v0.154.0 (22:35 UTC 9 Sep): GPT-6 Astra in the model picker and Amazon Bedrock catalogs; experimental --worktree / /worktree isolated checkouts; inline answers while a turn runs; Windows background server. Deprecated codex mcp-server entry point is gone.1

Claude Code v2.1.267 (19:58 UTC 9 Sep): maxEffortLevel cap across Bedrock/Vertex/Foundry; --system-prompt-snapshot off; a long list of prompt-cache, resume, MCP, and VS Code fixes after yesterday's 2.1.266 gateway pin. npm dist-tags: latest/next 2.1.267, stable still 2.1.236.23

MAI-Code-1-Flash is off Copilot as of today (10 Sep). Enterprise Copilot admins also get GA managed permissions for agent shell/file/network ops that users cannot weaken.4

VERDICT · USE IT — Codex users who want Astra: ≥0.154.0. Claude Code: pin ≥2.1.267. Expect MAI-Code-1-Flash gone from Copilot. Copilot Business/Enterprise admins: review agent permission policies.

The conversation

01
The claim — including ours

Astra is in the Codex binary now; quota colour continues without a new rate page in-window.56

From the floor
  • X digests 9 SepBackground · collected 05:30 UTC 9 Sep (~24.5h; accounts roster + keyword MD fallback)

    Keyword X MD present; accounts JSON thin. No 10 Sep collection — layer is background only.5

  • Reddit live pulse 10 SepLive · 6 subreddits, ranked by comments

    Astra build demos, DeepSeek-V4-Flash-Vision field reports, image 2.5 comparisons — user reports, not pins.6

  • OpenAI statusPrimary

    Pro/Plus conversation errors ~1.1h minor resolved; shared Project direct-link blip open/minor; usage-limit reset noise 0.4h impact none. No Anthropic/Cursor major in-window.7

Our take

Ship Codex 0.154 and Claude Code 2.1.267. Treat Astra quota threads as colour until a vendor rate page moves.

Releases: 28 repos, complete, unauthenticated public API, 16 non-prerelease in-window (monorepo noise folded in candidates). Vendor feeds: 12 sources, complete, 13 in-window. X digests stop at 9 Sep 05:30 (~24.5h — background; no 10 Sep file). Reddit: no fresh digest; live pulse 9 posts. HN Algolia thin via Exa. arXiv not swept. npm dist-tags via registry.npmjs.org.
