# DeepSpeed vs LlamaFactory

DeepSpeed and LlamaFactory share 9 technologies: accelerate, sentencepiece, torch, transformers, einops, safetensors, liger-kernel, torchvision, and Pydantic. 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.
- [hiyouga/LlamaFactory](https://seerepo.com/r/hiyouga/LlamaFactory): Unified Efficient Fine-Tuning of 100+ LLMs & VLMs (ACL 2024)

## What they share and what sets them apart

- In common: accelerate, sentencepiece, torch, transformers, einops, safetensors, liger-kernel, torchvision, Pydantic
- Only in DeepSpeed: sphinx-rtd-theme, triton, diffusers, comet-ml, lm-eval, xgboost, docutils, psutil
- Only in LlamaFactory: FastAPI, uvicorn, Gradio, matplotlib, tiktoken, triton-ascend, datasets, trl, peft, deepspeed, ModelScope, torchaudio, bitsandbytes, nltk, torchdata, torchcodec, av, jsonschema-specifications, referencing

| Activity | Last push November 6, 2026, 3,619 commits, 43,302 stars | Last push November 4, 2026, 2,769 commits, 75,890 stars |
| Tests | 395 test files. 33% of its code files have a test that imports them | 62 test files. 38.1% 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.
