# Multimodal Capabilities

<Info>
  This feature is available on all Portkey [plans](https://portkey.ai/pricing).
</Info>

The Gateway is your unified interface for **multimodal models**, along with chat, text, and embedding models.

Using the Gateway, you can call `vision`, `audio (text-to-speech & speech-to-text)`, `image generation` and other multimodal models from multiple providers (like `OpenAI`, `Anthropic`, `Stability AI`, etc.) — all using the familiar OpenAI signature.
