LLM Deprecation & Price-Change Tracker

Every scheduled model shutdown, API retirement and price change we've verified — published as a reusable dataset. Missing one of these costs real engineering pain, or real money.

129tracked retirement dates across 4 providers

Methodology. Compiled from the providers' own deprecation and retirement pages — OpenAI's deprecations page, Anthropic's model-deprecations page, Google's Vertex AI model-versions page and Microsoft's Azure OpenAI model-retirements page. Every row carries the source URL it was read from. Where a provider publishes only a hedged date ("May 19, 2027 or later"), the wording is kept verbatim rather than rounded to false precision; rows whose shutdown date passed before 2025-01-01 are excluded. The CSV and JSON below are generated from the same dataset at build time — never hand-typed.

Every published model retirement — 129 rows across 4 providers

Read from the providers' official deprecation/retirement pages (Anthropic, Azure OpenAI, Google Vertex AI, OpenAI), snapshot taken 2026-08-06. Rows whose exact shutdown date is before 2025-01-01 are omitted; where a page gives no exact date, its verbatim wording is kept. Exact-dated rows first, in date order. Linked models have a pricing page here.
