Gemini 3.8 Flash benchmark scores

Google has released Gemini 3.8 Flash, which according to a post by X user leo 🐾 provides approximately Opus 5 performance at a much lower cost while being super fast. The user notes that real-world performance may not match Opus 5, citing benchmark discrepancies such as TBench 2.1 vs 4, but still considers it a good release.

leo 🐾 on X: "Google have, dare I say... RELEASED A GOOD MODEL 🥹 Gemini 3.8 Flash provides ~Opus 5 performance at much lower cost, while being super fast" In real-world use it won't be as capable as Opus 5 I'm sure the usual benchmark fishiness can be smelt here, look at TBench 2.1 vs 4 , but still a pretty good release all things considered
