DeNovoSWE: Scaling Long-Horizon Environments for Generating Entire Repositories from Scratch
DeNovoSWE is a large-scale dataset for whole-repository generation, as introduced in the paper "DeNovoSWE: Scaling Long-Horizon Environments for Generating Entire Repositories from Scratch".
🔥 Highlights
- 4,818 high-quality instances.
- 11k filtered trajectories from 34k DeepSeek-v4-High trajectories.
- Strong performance: 50% in BeyondSWE-Doc2Repo trained from Qwen3.5-35B-A3B.
📣 News
- 2026-06-10 🚀 We released part of our data on Hugging Face. from DeepSeek-v4-High.
- 2026-06-10 📝 Our paper "DeNovoSWE: Scaling Long-Horizon Environments for Generating Entire Repositories from Scratch" is now available on arXiv.
FAQ
- For evaluation of DeNovoSWE-Data, you can use AweAgent and refer to this recipe.
