PrimeIntellect introduced Prime Agent, a general-purpose coding harness (RLM) designed for coding and long-running autonomous tasks.
- On the ARC-AGI-3 benchmark, the framework achieved a high score of 95.5%, surpassing the human-expert baseline.
- Notably, this performance gain is not benchmark-specific (non-ARC specific harness).
- Compared to their proprietary harnesses, Prime Agent demonstrates significant cross-model performance improvements.
