Claude Fable 5.2 edges Gemini 4 Carbon on Google benchmark, but at higher cost

By PulseAugur Editorial · [1 sources] ·

Anthropic's Claude Fable 5.2 has reportedly outperformed Google's Gemini 4 Carbon on a specific benchmark designed by Google. The Fable model achieved a score of 73.3% compared to Gemini 4 Carbon's 71.9% on visual office tasks. However, this marginal difference was noted as potentially insignificant by Google's own report, and Claude Fable 5.2 was found to be six times more expensive to operate. AI
