DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

A bundled guide walks your project through upgrading the anthropic Python SDK to 1.x.

/claude-api upgrade
What

A new reference document ships inside Claude Code, reached from the /claude-api upgrade flow, walking a project through the 0.x to 1.x migration step by step.

Details
  • Steps covered: bump the pin, raise the Python floor to 3.10, move httpx objects that cross the SDK boundary to the httpx2 fork or call httpx2.alias_httpx() at an entry point, await .with_raw_response body reads on async clients, port completions.create plus HUMAN_PROMPT/AI_PROMPT to Messages, drop temperature/top_p/top_k, rewrite raw output_format={...} as output_config={"format": {...}}, and supply an explicit Bedrock region.
  • The document is a plain text constant in the bundle with no gate around it.
Evidence

# Upgrading the anthropic Python SDK: 0.x → 1.x

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
