# Frontier AI models: February 2026

> Three frontier models in fourteen days - Claude Opus 4.6, Claude Sonnet 4.6 and Gemini 3.1 Pro - opened the fastest release year on record.

## Direct answer

Three frontier AI models shipped in February 2026: Claude Opus 4.6 from Anthropic on February 5, Claude Sonnet 4.6 on February 17, and Gemini 3.1 Pro from Google on February 19. All three landed inside fourteen days, and the month is the point at which reliable multi-file coding and multimodal reasoning stopped being demos and became defaults. For working professionals, February 2026 is when junior-to-mid software tasks and routine research synthesis became reliably automatable.
