Anthropic model switched off
claude-3-5-haiku-latest, an Anthropic model that answered questions, wrote emails and was blamed for both, was switched off on February 19, 2026. The death was announced 2 months in advance, on December 19, 2025, on a deprecations page that most of its users never opened. Code that still calls it will find out the hard way.
Its work passes to claude-haiku-4-5-20251001, which the family describes as 'recommended'.
