What this page is
LLMs are sunset regularly. This page tracks every major deprecated model with its replacement, sunset window, and a migration note. Use it to plan rollovers before your code breaks. Seed data curated; full deprecation feed coming via our changelog pipeline. Open-source models are included when the original API host discontinued them.

Top migration paths
OpenAI
gpt-3.5-turbo → gpt-4o-mini
Lower price ($0.15/M vs $0.50/M input), higher quality, larger context. Drop-in replacement for nearly all use cases.
Anthropic
claude-2.1 → claude-3-haiku
Faster, cheaper, better benchmark scores, 200K context. Upgrade to Sonnet 4 or Opus 4 for higher quality tiers.
Google
palm-2 → gemini-2.5-flash
Entire PaLM line retired. Gemini 2.5 Flash is faster, cheaper, and multimodal. Migrate sooner rather than later.
Frequently asked questions
The model is no longer recommended by its vendor. API access may continue for a while, but new features, performance improvements, and SLAs often do not apply. After the sunset date, requests typically fail or redirect to a replacement model.
