# DeepSpeed vs mamba

DeepSpeed and mamba share 4 technologies: torch, transformers, triton, and einops. 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.
- [state-spaces/mamba](https://seerepo.com/r/state-spaces/mamba): Mamba SSM architecture

## What they share and what sets them apart

- In common: torch, transformers, triton, einops
- Only in DeepSpeed: sphinx-rtd-theme, accelerate, sentencepiece, diffusers, safetensors, comet-ml, liger-kernel, lm-eval, torchvision, xgboost, docutils, Pydantic, psutil
- Only in mamba: apache-tvm-ffi, quack-kernels

## Side by side

| | DeepSpeed | mamba |
|---|---|---|
| Size | 247,033 lines written, 760 code files | 28,235 lines written, 43 code files |
| Who writes it | 2.7% of its commits signed by AI. With GitHub Copilot, Cursor, and Claude Code | 0.5% of its commits signed by AI. With GitHub Copilot |
| Activity | Last push November 6, 2026, 3,619 commits, 43,302 stars | Last push July 22, 2026, 219 commits, 18,976 stars |
| Tests | 395 test files. 33% of its code files have a test that imports them | 11 test files. 51.2% 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.
