Predicting Agent Coding Task Performance
๐กPredict coding task failures for LLM agents without expensive evals
โก 30-Second TL;DR
What Changed
Augments IRT with task features like issues, repos, solutions, tests.
Why It Matters
Reduces compute costs for agent evaluations by predicting hard tasks upfront. Enables better benchmark design and cross-evaluation comparisons. Advances understanding of agent weaknesses in coding.
What To Do Next
Implement IRT-based prediction using task features for your coding benchmarks.
Key Points
- โขAugments IRT with task features like issues, repos, solutions, tests.
- โขDecomposes agent ability into LLM and scaffold components.
- โขPredicts performance on unseen benchmarks and agent combos.
- โขHelps benchmark designers calibrate task difficulty without full evals.

๐ Enhanced Key Takeaways
- โขThe framework addresses the 'benchmark saturation' problem by modeling task difficulty as a latent variable, allowing researchers to estimate performance on new tasks without requiring expensive, full-scale execution of agentic workflows.
- โขBy isolating the scaffold component (the agent's orchestration logic) from the LLM component, the model can predict how a specific agent would perform if its underlying model were swapped for a more capable or specialized version.
- โขThe approach utilizes a Bayesian estimation method to handle sparse data scenarios, where an agent may have only attempted a small subset of tasks within a large, diverse repository of coding challenges.
