Research Papers

Harness Continual Learning and Harness-Level Forgetting — Omar Sarroub et al.

• Motivation: Modern AI agents accumulate experience inside their execution harnesses (prompts, tool configs, memory) rather than model weights. Modifying harness components often silently degrades previously reliable agent performance.
• Key Innovation: Identifies “harness-level forgetting” and proposes Guarded Harness Evolution, which utilizes a Continual Optimizer to draft candidate harness updates and a Continual Evaluator to verify historical retention before committing changes.
• Results: Effectively eliminates harness degradation and yields >10% relative performance improvements across textual reasoning and multimodal agent benchmarks.
• Paper: ArXiv Pre-print

Analyzing Agentic Post-Training Trajectories — Research Team

• Motivation: Investigating whether autonomous AI agents can effectively post-train other agents without getting stuck in localized, repetitive loops.
• Key Innovation: Discovers that post-training agents lock into strategy choices on step one and spend their compute budget strictly on local adjustments. Introduces an experience-driven scaffolding approach allowing agents to re-evaluate strategies during runtime execution.
• Results: Outperforms baseline unguided post-training agents by +12.6 points on GSM8K and +40.8 points on HumanEval.
• Paper: ArXiv Pre-print
