# DeepSpeed vs unsloth

DeepSpeed and unsloth share 9 technologies: accelerate, sentencepiece, torch, transformers, einops, diffusers, safetensors, Pydantic, and psutil. Both are written in Python.

- [deepspeedai/DeepSpeed](https://seerepo.com/r/deepspeedai/DeepSpeed): DeepSpeed is a deep learning optimization library that makes distributed training and inference easy, efficient, and effective.
- [unslothai/unsloth](https://seerepo.com/r/unslothai/unsloth): Local UI to run and train LLMs and diffusion models. Supports GGUF, MLX, Qwen3.8, DeepSeek-V4.1, MiniMax-H3, Gemma 4, FLUX and more.

| Who writes it | 2.7% of its commits signed by AI. With GitHub Copilot, Cursor, and Claude Code | 1% of its commits signed by AI. With Claude Code, Gemini CLI, Cursor, Codex, and GitHub Copilot |
| Activity | Last push November 6, 2026, 3,619 commits, 43,302 stars | Last push November 4, 2026, 12,770 commits, 79,050 stars |
| Tests | 395 test files. 33% of its code files have a test that imports them | 5,718 test files. 60.3% of its code files have a test that imports them |

- Size: Lines written by people and agents, without generated ones; code files, without tests.
- Who writes it: A commit counts as AI's when it carries its signature: a Co-Authored-By line, its author name or the merge of its branch.
- Activity: From GitHub and its history, on the day SeeRepo read it.
- Tests: The files that test the code, and the share of code files a test imports.
