Python SDK v1.0 ships with httpx2 migration and legacy API removal
Anthropic released Python SDK v1.0: the HTTP layer moves from httpx to the maintained httpx2 fork (requires Python 3.10+). Long-deprecated surface is removed, including the legacy Text Completions API, `temperature`/`top_p`/`top_k` on Messages, and the tool runner's client-side `compaction_control`. Async `.with_raw_response` now needs `await response.parse()`. See the v1 migration guide for full breaking changes.

Anthropic graduated four major platform features: computer use (`computer_toolset_20260801`) and a new browser use toolset no longer need beta headers; Files API and Agent Skills (/v1/skills) are GA too. All four work on Fable 5, Mythos 5, Opus 5, and Sonnet 5.

New Claude models embed an invisible SynthID-Text watermark in generated text, applied globally (not EU-only). The mark carries no user or org identifiers and adds no extra tokens; older models will receive watermarking over the coming months.

Since Aug 14, new Claude Code sessions on Pro, Max, and Team run in auto mode — a classifier approves routine tool calls instead of prompting. Classifier token overhead is no longer charged on these plans; Enterprise and API access remain opt-in for now.

Anthropic cancelled the planned Sep 1 increase to $3/$15 per million tokens. Sonnet 5 stays at $2 input / $10 output per MTok as the standard API price.

Anthropic retuned Fable 5's biology safety classifiers so benign health and education queries trigger fewer fallbacks to Opus 5 — about 85% fewer biology-related fallbacks in testing. Dual-use requests (virology, toxicology, molecular design) still route to the less capable model; trusted-access pathways for frontier biology remain in development.

Anthropic ended support for claude-opus-4-1-20250805 after a 60-day deprecation window. API calls to the old model ID now return errors; Opus 4.8 and Opus 5 are the recommended replacements.

Opus 5 targets coding and knowledge work with thinking enabled by default. Available on Claude.ai, Claude Code, and the API at $5/$25 per million tokens — same pricing as Opus 4.8.
