“The Remote Labor Index (RLI) measures how often AI agents can complete real, economically valuable freelance projects (3D & CAD, architecture, graphic design, video and animation, audio, data analysis, web apps, and more) at a quality a paying client would actually accept. Every deliverable is judged by human evaluators against a gold-standard deliverable produced by a paid professional. The headline metric, the automation rate, is the share of projects where the AI’s work is judged as good as (or better than) the human’s.

At the benchmark’s release, the best AI agent automated just 2.5% of projects. Today we’re publishing results for three newer models, paired with stronger agent scaffolding. Automation rate is rapidly increasing…

Fable 5 reaches the highest automation rate measured so far, 16.1%, roughly double Opus 4.8 at 8.3%. GPT‑5.5 reaches 6.3%. All three score above every previously evaluated model.

For context, the previous published leader sat at 4.17% (Opus 4.6 with the Claude Cowork scaffold), and the field topped out at 2.5% when RLI was released. The frontier has more than quadrupled in under eight months, a concrete signal of how quickly economically capable AI agents are advancing.”
