The constant exists; whether it is sent depends on callers elsewhere.

What

The table of API beta headers is now a plain top-level list and gained a redact_thinking entry dated 2026-02-12, alongside the existing tool search, web search and Claude Code betas. Whether that header is attached to requests depends on callers elsewhere in the bundle; the constant existing does not mean it is sent.

Evidence

Te("redact_thinking", "redact-thinking-2026-02-12")

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