AI completes 16% of the freelance tasks in Remote Labor Index CAIS updated the Remote Labor Index — a benchmark where AI agents complete real client projects: design, video, CAD, architecture, analytics, and web apps. The work is reviewed by humans and compared against a professional deliverable that a paying client would accept. New results: • Claude Fable 5 — 16.1% • Claude Opus 4.8 — 8.3% • GPT-5.5 — 6.3% Fable 5 is now the top model in RLI and almost 2x higher than Opus 4.8. When the benchmark launched, the best result was 2.5%.
