Gemini 4 Pro checkpoint spotted on Arena as leak claims full release weeks away
lyraxana · x · 2026-09-29
A new Gemini 4 Pro checkpoint with extended thinking has appeared on the Arena AI leaderboard. Early testers are unimpressed, arguing Google's Pro models are only medium-sized and urging a return to an Ultra-class model, claiming Google releases are 'nerfed on day one.'
An unverified internal leak claims Gemini 4 is being prepped for release within weeks, but that this checkpoint is a 'gnat' compared to Opus 5.5 and not the Gemini 4 worth waiting for — the release version may be better or worse. All claims are unconfirmed.
