(new-model)= # Adding a New Model This section provides more information on how to integrate a [PyTorch](https://pytorch.org/) model into vLLM. :::{toctree} :caption: Contents :maxdepth: 1 basic registration tests multimodal ::: :::{note} The complexity of adding a new model depends heavily on the model's architecture. The process is considerably straightforward if the model shares a similar architecture with an existing model in vLLM. However, for models that include new operators (e.g., a new attention mechanism), the process can be a bit more complex. ::: :::{tip} If you are encountering issues while integrating your model into vLLM, feel free to open a [GitHub issue](https://github.com/vllm-project/vllm/issues) or ask on our [developer slack](https://slack.vllm.ai). We will be happy to help you out! :::
