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.
