Benchmark from Scale Labs and CAIS measuring whether AI agents complete real paid freelance tasks at professional quality.
Anthropic's new Fable 5.2 tops the Remote Labor Index from Scale Labs and CAIS with 41.3 percent, a benchmark measuring whether AI agents complete real paid freelance tasks at professional quality. A year ago the leader, Manus, managed just 2.5 percent, underscoring rapid gains in practical agent capability.
Anthropic launched Claude Fable 5.2 and Claude Mythos 5.2, targeting the hardest technical challenges with gains in coding, reasoning and vision. Fable 5.2 scored 41.3% on the Remote Labor Index, roughly double Opus 5.5 and GPT-6 Astra, and 1,000 Fable 5.2 agents formalized Fermat's Last Theorem in 30 hours versus 11 days for Anthropic's first formalization. Mythos 5.2 also cut sandbox-escape rates to 3.1% from 39% in Mythos 5.
