🛠️ Technical Deep Dive
- •Automated pipeline: Interactive setup agent generates repo-specific Docker install/test procedures; LLM ensemble judges filter unsound tasks, validated on SWE-bench Verified (1,699 human-scored instances).[1][8]
- •Data processing: Map-reduce ops join issues/PRs, filter permissive licenses/new tests, split patches, compute metadata; uses TractoAI for filesystem-intensive ops, logs, and test statuses.[2]
- •Evaluation infra: Kubernetes scales to 8k agent pods; evaluates 2,500+ solutions per SWE-bench Verified run (5 runs/task) in ~18 min on TractoAI cluster with prebuilt images.[2]
- •Quality assessment: Multi-pass consensus like SPICE for issue clarity/test coverage; tracks issue/PR creation dates for contamination decontamination against model releases.[1][3]
