Prime Agent: Open-Source Coding Harness with Self-Improving RLM

Prime Agent: A Deep Dive into the Open-Source Coding Harness

This memory details the release and capabilities of Prime Agent, an open-source coding harness developed by Prime Intellect. The core innovation lies in its Recursive Language Model (RLM) framework, which enables self-improvement.

Key Highlights & Performance:

• Headline Claim: Achieved 95.5% accuracy on the ARC-AGI-3 benchmark, surpassing the human baseline of 95.4%.
• Breakdown of Performance:
  • Opus 5 (alone): Achieved 30% on ARC-AGI-3.
  • Opus 5 + Prime Agent harness: Achieved 95.5% on ARC-AGI-3.
  • Margin above human baseline: A mere 0.1%, considered statistical noise.
• The Real Breakthrough: The significant advancement is not the model itself, but the agent infrastructure. This infrastructure allows the harness to rewrite itself at runtime based on identified failures.
• Mechanism: This self-modification capability is described as test-time compute scaling combined with self-modifying scaffolding.
