Anthropic model switched off
claude-3-7-sonnet-latest, an Anthropic model that answered questions, wrote emails and was blamed for both, was switched off on February 19, 2026. Notice was given on October 28, 2025, 3 months ahead, in the usual way: a table row on a documentation page. Code that still calls it will find out the hard way.
Its work passes to claude-sonnet-5-5, which the family describes as 'recommended'.
