ARC-AGI 3 is now completely saturated (solved) by a new AI harness called Prime Agent!
It achieved its highest score with Opus 5, but it can work with any other model too. It's especially well suited for agentic coding tasks.
Incredible achievement by
@PrimeIntellect 🔥
Introducing Prime Agent:
A self-improving RLM harness for coding and long-running autonomous tasks.
Designed to be both token-efficient and expressive through programmatic tool calling, context as a variable, multi-agent messaging, and a self-modifiable harness state.
