 IO Processor plugins are a feature that allows pre and post processing of the model input and output for pooling models. The idea is that users are allowed to pass a custom input to vLLM that is converted into one or more model prompts and fed to the model `encode` method. One potential use-case of such plugins is that of using vLLM for generating multi-modal data. Say users feed an image to vLLM and get an image in output.
 
-When performing an inference with IO Processor plugins, the prompt type is defined by the plugin and the same is valid for the final request output. vLLM does not perform any validation of input/output data, and it is up to the plugin to ensure the correct data is being fed to the model and returned to the user. As of now these plugins support only pooling models and can be triggerd via the `encode` method in `LLM` and `AsyncLLM`, or in online serving mode via the `/pooling` endpoint.
