February 2026 Shapes Up as the Most Crowded Model Release Month in AI History

Sonnet 5, Gemini 3 Pro, GPT 5.3, GLM-5, and at least four other major models are all reportedly scheduled for February — but early Gemini 3 GA testers say hallucinations persist.

A widely circulated thread from @chetaslua catalogs what may be the densest month of model releases ever: Anthropic's Sonnet 5, Google's Gemini 3 Pro and Flash GA plus a model code-named Snowbunny, OpenAI's GPT 5.3, MiniMax m2.5, and Zhipu's GLM-5 are all expected before month's end. The sheer volume means that any model released this month has approximately 48 hours of attention before the next one lands.
