## News

- **2026-05:** 🎉 daVinci-Dev was accepted as an **oral presentation** at ICML 2026.
- **2026-01:** daVinci-Dev paper, code and dataset were released!

## Overview

`daVinci-Dev` is a family of large language models trained for **agentic software engineering**.

This repo provides:

- The paper PDF: [`daVinci-Dev.pdf`](./daVinci-Dev.pdf)
- A high-performance data processing pipeline under [`pipeline/`](pipeline:1) that calls the GitHub API to construct **contextually-native PR trajectories** $\mathcal{D}^{\text{ctx}}_{\text{py}}$

## Model Zoo

We will open-source model checkpoints on Hugging Face:

| Model | Description | Link |
|------|-------------|------|
| `daVinci-Dev-72B` | Final model (agent-native mid-training + env native SFT) | https://huggingface.co/GAIR/daVinci-Dev-72B |
| `daVinci-Dev-32B` | Final model (agent-native mid-training + env native SFT) | https://huggingface.co/GAIR/daVinci-Dev-32B |
| `daVinci-Dev-72B-MT` | **MT checkpoint** (after agent-native mid-training, **before SFT**) | https://huggingface.co/GAIR/daVinci-Dev-72B-MT |
| `daVinci-Dev-32B-MT` | **MT checkpoint** (after agent-native mid-training, **before SFT**) | https://huggingface.co/GAIR/daVinci-Dev-32B-MT |

## Datasets

Datasets are released through Hugging Face:

| Dataset | Description | Link |
|---------|-------------|------|
| `daVinci-Dev` | Agent-native trajectories used in our training recipe (as permitted) | https://huggingface.co/datasets/GAIR/daVinci-Dev |

High-level composition (see the paper for details):

- **Contextually-native trajectories** $\mathcal{D}^{\text{ctx}}_{\text{py}}$ (PR-derived, Python variant)
- **Environmentally-native trajectories** $\mathcal{D}^{\text{env}}_{\text{pass}}$ (executable rollouts, test-passing subset)

## Pipeline

The directory [`pipeline/`](pipeline:1) contains a high-performance pipeline that calls the GitHub API and constructs the structured PR representation used to build $\mathcal{D}^{\text{ctx}}_{\text{py}}$.

| Pipeline | Description | Link |
|----------|---------|-------------|
| daVinci-Dev Pipeline | a high-performance pipeline used to build $\mathcal{D}^{\text{ctx}}_{\text{py}}$ | [`pipeline/`](pipeline:1) |

## Utilities for Environmentally-native Trajectories

The directory [`env_traj_utils/`](env_traj_utils/) provides utilities for converting environmentally-native trajectories ($\mathcal{D}^{\text{env}}$) to LLM-trainable formats:

| Script | Description |
|--------|-------------|
| [`convert_trajectories.py`](env_traj_utils/convert_trajectories.py) | Convert SWE-agent trajectories to XML function calling format |
| [`tokenize_trajectories.py`](env_traj_utils/tokenize_trajectories.py) | Tokenize trajectories and filter by length |

See the [env_traj_utils README](env_traj_utils/README.md) for quickstart instructions on converting [`env-native.jsonl`](https://huggingface.co/datasets/GAIR/daVinci-Dev/blob/main/env-native.jsonl) to formats compatible with training frameworks like [SLIME](https://github.com/THUDM/slime).

## License

This project is a **mixed** release:

- **PR-derived subset:** only includes PRs from repositories detected as having a **permissive license** in the open-source release.
- **Executable rollout subset:** derived from [SWE-rebench](https://huggingface.co/datasets/nebius/SWE-rebench), licensed under **CC-BY-4.0**.
- **daVinci-Dev models:** released under [Qwen](https://huggingface.co/Qwen/Qwen2.5-72B-Instruct/blob/main/LICENSE) license. Users should verify the licensing status of any generated code before using it in production.
- **daVinci-Dev pipeline:** released under the [Apache-2.0](https://github.com/GAIR-NLP/daVinci-Dev/blob/main/LICENSE) license.

Downstream users are responsible for ensuring their usage complies with the licenses of the underlying sources.
