Explore DeepSeek Harness open-source repository on GitHub. Track latest releases, Cordis plugin architecture, and Agent benchmark updates.
Core Project Pillars
Model + Harness = Agent Paradigm
Decouples base reasoning LLMs from execution scaffolding. Deeply integrates unambiguous TypeScript tool contracts, high-throughput bash execution engines, and precision multi-chunk code diff replacement algorithms.
Containerized Docker Sandboxing
All shell commands and multi-file code refactorings execute safely inside lightweight Docker container sandboxes with strict hardware limits on CPU, memory, and disk I/O for dependable and risk-free operations.
DSBench & Automated Self-Correction
Built-in automated pytest integration and compiler error log stack trace extraction. Evaluates Pass@1 benchmarks via DSBench and LM-Eval suites to continuously trigger autonomous agent self-correction loops.
DeepSeek Prefix Cache Optimization
Deeply aligned with DeepSeek-V3/R1 native Prefix Caching mechanisms, achieving up to 99.93% prefix cache hit rates across multi-turn complex repository edits and reducing Token compute costs by 80%+.
