Claude Fable 5 leads AI performance leaderboard but is most expensive

By PulseAugur Editorial · [1 sources] ·

A new evaluation called gdpval-aa v2 measures AI model performance on real-world tasks, using an Elo rating system anchored to a human baseline. Anthropic's Claude Fable 5, Sonnet 5, and Opus 4.8 models secured the top three positions, outperforming models like Grok 4.5, GLM-5.2, and GPT-5.5. While the Claude models lead in raw performance, they are also the most expensive, with Grok 4.5 noted for offering a strong balance of performance and cost. AI

IMPACT Establishes a new benchmark for real-world task performance and highlights the trade-off between model capability and cost.
