--- title: Adding a New Model --- [](){ #new-model } This section provides more information on how to integrate a [PyTorch](https://pytorch.org/) model into vLLM. Contents: - [Basic](basic.md) - [Registration](registration.md) - [Tests](tests.md) - [Multimodal](multimodal.md) !!! 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!
