// como funciona

Como funciona

  1. Decide if you want speed or understanding

    Choose nano-vllm to run offline inference with a codebase small enough to read fully, or to prototype engine ideas quickly.

  2. Install the package

    Install nano-vllm directly from its GitHub repository with pip.

  3. Download model weights

    Fetch a model such as Qwen3-0.6B from Hugging Face to a local directory.

  4. Generate text

    Load the model with the LLM class, set SamplingParams, and call generate on your prompts, as in example.py.

Por que as pessoas gostam tanto

Readable from-scratch engine

The whole implementation is about 1,200 lines of clean Python, so you can actually read how inference works.

Fast offline inference

The README benchmark shows output throughput comparable to vLLM on the tested setup (Qwen3-0.6B, RTX 4070 Laptop).

Prefix caching

Reuses cached prefixes across requests to avoid recomputing shared prompt beginnings.

Tensor parallelism

Splits a model across multiple GPUs with the tensor_parallel_size setting when one GPU is not enough.

Torch compilation and CUDA graphs

Uses torch compilation and CUDA graphs as part of its optimization suite to cut inference overhead.

vLLM-like API

The LLM and SamplingParams interface mirrors vLLM, so existing vLLM-style code needs only minor changes.

Execute você mesmo

  1. Clone the repository

    Clone nano-vllm to read the source and run the included example and benchmark scripts.

    git clone https://github.com/GeeeekExplorer/nano-vllm.git
    cd nano-vllm
  2. Install from GitHub

    Install the package directly from the repository with pip.

    pip install git+https://github.com/GeeeekExplorer/nano-vllm.git
  3. Download a model and generate

    Download Qwen3-0.6B weights, then run example.py-style code with the LLM class and SamplingParams.

    huggingface-cli download --resume-download Qwen/Qwen3-0.6B --local-dir ~/huggingface/Qwen3-0.6B/ --local-dir-use-symlinks False

// perguntas frequentes

Perguntas frequentes

Who maintains nano-vllm?

It is a project by GeeeekExplorer with open-source contributors.

Is nano-vllm free to use?

Yes. It is released under the MIT license.

Does it need a paid API key?

No. It runs models locally on your GPU; you only download open model weights from Hugging Face.

How does it compare with vLLM itself?

Nano-vLLM trades vLLM's breadth (serving features, model coverage, production hardening) for a tiny, readable codebase with comparable offline throughput on the README's tested setup.

How do I get started?

pip install it from GitHub, download Qwen3-0.6B, and run the example in example.py.
