This endpoint returns a list of all multimodal AI models supported by the Helicone AI Gateway. Multimodal models are those that support more than one input modality (e.g., text + images) or more than one output modality. This is an OpenAI-compatible endpoint that follows the same response format as OpenAI’s /v1/models endpoint. Use this endpoint to discover which multimodal models are available for routing through the AI Gateway.

What Makes a Model Multimodal?

A model is considered multimodal if it meets either of these criteria:
  • Multiple Input Modalities: Accepts more than one type of input (e.g., text, images, audio)
  • Multiple Output Modalities: Produces more than one type of output (e.g., text, images, audio)
