GEMINI 3.5 PRO IS REPORTEDLY LAUNCHING WITH A 2 MILLION TOKEN CONTEXT WINDOW. Still unconfirmed by Google as of today. Every spec circulating comes from leaks and third-party reporting, not an official model card. Rumored GA date is July 17. If accurate, it would be roughly double Anthropic's extended context ceiling of 1M tokens (Fable 5's default is 200K, extendable via beta header) and meaningfully larger than GPT-5.6's reported roughly 1M tokens. Entire codebases, massive document sets, months of conversation history—in a single context—if the number holds and the model reasons reliably across that full range. Independent long-context research has repeatedly found performance degrades well before advertised limits on every frontier model tested so far. Context window is quietly becoming the differentiator nobody talks about enough. But treat this specific number as a rumor until Google actually confirms it.(CyrilXBT)
