Summary

Adds deprecation_date: 2026-11-30 to the anthropic Claude Sonnet 4.5 rows after Anthropic announced its retirement in the September 30, 2026 release notes. Prices, context windows and capability flags are unchanged

Rows

Key Field Value Kind
claude-sonnet-4-5-20250929 deprecation_date 2026-11-30 page
claude-sonnet-4-5 deprecation_date 2026-11-30 page (alias of claude-sonnet-4-5-20250929)

Evidence, fetched raw from https://platform.claude.com/docs/en/release-notes/overview.md

We announced the deprecation of the Claude Sonnet 4.5 model (claude-sonnet-4-5-20250929), with retirement on the Claude API scheduled for November 30, 2026

And from https://platform.claude.com/docs/en/about-claude/model-deprecations.md, model status table row

| claude-sonnet-4-5-20250929 | Deprecated | September 30, 2026 | November 30, 2026 |

claude-sonnet-4-5 is the undated alias that resolves to the claude-sonnet-4-5-20250929 snapshot and carries the same prices, so it gets the same retirement date. The /v1/models list no longer returns the alias

Other checks

The pricing API for anthropic is page based (structured: false). The base input and output prices on https://platform.claude.com/docs/en/about-claude/pricing.md match every priced anthropic row in the catalog, so no price changes

Delisted by the provider

Absent from /v1/models for our key, rows kept unchanged: claude-haiku-4-5, claude-opus-4-5, claude-mythos-5, claude-mythos-5-1, claude-mythos-preview. claude-haiku-4-5 and claude-opus-4-5 are undated aliases whose snapshots are still listed and Active ("Not sooner than October 15, 2026" and "Not sooner than November 24, 2026", not firm dates). claude-mythos-5 and claude-mythos-5-1 stay flagged as delisted per ruling anthropic-mythos-gated-flag-delisted. claude-mythos-preview already carries deprecation_date: 2026-06-09


Note

Low Risk
Metadata-only catalog update with no pricing or runtime behavior changes.

Overview
Adds deprecation_date: 2026-11-30 to the Anthropic claude-sonnet-4-5 and claude-sonnet-4-5-20250929 entries in model_prices_and_context_window.json and its backup, reflecting Anthropic’s announced API retirement. Pricing, context limits, and capability fields are unchanged.
