# Features

https://modelportal.ai/docs/features

This group covers each feature across the three protocols and how the platform handles it:

- [Streaming](/docs/streaming), [Tool calling](/docs/tool-calling), [Structured output](/docs/structured-output), [Prompt caching](/docs/prompt-caching), [Reasoning](/docs/reasoning).
- [Anthropic Messages API](/docs/anthropic-messages) and [Gemini API](/docs/gemini-api): where they differ from the OpenAI format.
- [Parameter mapping](/docs/parameter-mapping): how parameters line up across protocols, and what happens when an endpoint lacks one.
