# models vs vllm

models and vllm share 7 technologies: FastAPI, einops, torch, torchvision, sentencepiece, pillow, and psutil. Both are written in Python.

- [tensorflow/models](https://seerepo.com/r/tensorflow/models): Models and examples built with TensorFlow
- [vllm-project/vllm](https://seerepo.com/r/vllm-project/vllm): A high-throughput and memory-efficient inference and serving engine for LLMs

## What they share and what sets them apart

- In common: FastAPI, einops, torch, torchvision, sentencepiece, pillow, psutil
- Only in models: Google, Google Cloud Storage, matplotlib, seaborn, google-auth-oauthlib, cupy-cuda12x, TensorFlow, tf-keras, opencv-python, scikit-image, scikit-learn, nltk, tritonclient
- Only in vllm: axum, gitdb, pyzmq, Hugging Face, Tokio, starlette, Ray, AIOHTTP, tower, mkdocs-material, indicatif, NVIDIA, OpenAI, peft, quack-kernels, transformers, safetensors, triton, datasets, torchaudio, MCP, tokenizers, tiktoken, markdown, markupsafe, pymdown-extensions, image, jinja2, Pydantic, msgspec, jsonschema, pydantic-core, opentelemetry-api, python-json-logger, tracing, prometheus-client, tracing-subscriber, OpenTelemetry, opentelemetry-sdk, prometheus-fastapi-instrumentator

## Side by side

| | models | vllm |
|---|---|---|
| Size | 644,066 lines written, 1,857 code files | 2,375,117 lines written, 3,289 code files |
| Who writes it | 0% of its commits signed by AI | 12.8% of its commits signed by AI. With Claude Code, Codex, Gemini CLI, Cursor, GitHub Copilot, Devin, Mistral Vibe, CodeRabbit, Factory, and Qwen Code |
| Activity | Last push November 2, 2026, 8,558 commits, 77,633 stars | Last push November 4, 2026, 24,593 commits, 96,302 stars |
| Tests | 778 test files. 45.4% of its code files have a test that imports them | 2,419 test files. 60.2% 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.
