The VoxelBench leaderboard shows Google's new Gemini 4 Argon debuting at #5 — not matching Anthropic or OpenAI frontier models, but a 13-place jump over Google's previous best at #18. Blogger legitapi reads it as roughly Opus 5-level, a solid step up from Gemini Flash yet a tier below Astra and Opus 5.5, and flags rumored Claude Fable 5.5 as the next model to watch.
