The one thing

01

anthropic Python SDK hits 1.0 — httpx2, Python 3.10+, Text Completions gone.

v1.0.0 published 20 Aug: HTTP layer moves from unmaintained httpx to Pydantic's httpx2 fork. Minimum Python rises from 3.9 to 3.10. Legacy Text Completions (client.completions.create, HUMAN_PROMPT / AI_PROMPT) are removed. .with_raw_response returns the same APIResponse / AsyncAPIResponse classes as streaming — async parse/read/text/json are coroutines; .text and .content are methods.12

Custom httpx clients, transports, and isinstance checks must switch to httpx2 (or httpx2.alias_httpx() at startup so tracers and mocks still see traffic). Bedrock clients now raise if no AWS region resolves instead of falling back to us-east-1. MIGRATION.md documents the rest; Claude Code can run /claude-api upgrade python.2

VERDICT · BREAKING — Pin anthropic>=1.0.0 only after you clear MIGRATION.md. If you construct HTTP clients or mock httpx, switch imports to httpx2 first. Drop any remaining Completions callers. Python <3.10 stays on 0.125.x.
Deeper — what actually breaks
  • Plain timeout/retry kwargs usually need no edit; objects you pass into the client do.2
  • APM/mock libraries that patch httpx silently miss SDK traffic until pointed at httpx2.2
  • Header merge is case-insensitive; bytes header values are rejected.2

pydantic-ai 2.33.0 · emergency Anthropic 1.0 pin

anthropic 1.0.0 hit PyPI on 20 Aug. Earlier pydantic-ai releases, including v2.32.2 cut hours earlier, allowed it without supporting it — a fresh pydantic-ai[anthropic] install could resolve 1.0.0 and fail at runtime. v2.33.0 requires and supports anthropic>=1.0.0. Stay on older pydantic-ai only with anthropic<1. Custom http_client on AnthropicProvider must be httpx2.AsyncClient.3

Codex rust-v0.149.0 · agents dashboard, queue, cwd commands

Interactive codex agents dashboard searches, starts, opens, renames, and stops tasks. codex queue sends messages into existing local or remote sessions. TUI gains /cd, /pwd, /cwd. codex doctor covers endpoint protection, proxy failures, desktop app state, and update connectivity. SDK callers can pass exact CLI config overrides and select max or ultra reasoning effort. Resumed/forked threads restore their permission profile instead of silently resetting.4

The conversation

01
The claim — including ours

Anthropic's Python SDK went major the same window pydantic-ai had to ship an emergency pin, while Codex added a multi-agent control surface.134

From the floor
  • anthropic-sdk-python v1.0.0 + MIGRATION.mdVendor, dated

    httpx2 client, Python ≥3.10, Text Completions removed, raw-response class change, Bedrock region required.12

  • pydantic-ai v2.33.0Vendor, dated

    Explicit apology for the breakage window; pin anthropic≥1.0.0 or stay on anthropic<1 with older pydantic-ai.3

  • X accounts digest · 20 Aug 05:30Digest ~24.5h old at window close — background

    Brockman pitched Codex as a general harness (tax-prep pilot); field notes on Claude Code Concise and project-scoped /config — colour, not a ship decision.

Our take

Treat anthropic 1.0 as a planned break: read MIGRATION.md, upgrade pydantic-ai the same day, then pin. Grab Codex 0.149 if you juggle multiple agent sessions.

GitHub releases: 28 watchlist repos, sweep_complete true, authenticated, 18 in-window (llama.cpp nightlies and AI SDK monorepo patches collapsed). Vendor feeds: 12 sources, sweep_complete true, 15 in-window. X accounts digest (roster ~100) and X keyword digest last collected 05:30 UTC 20 Aug (~24.5h old at window close) — background only. Reddit: fresh pulse (6 subreddits, 9 posts). HN: no thread carried a primary for today's ships. arXiv not swept.
