Get Multimodal Models

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)

Example Request#

curl https://ai-gateway.helicone.ai/v1/models/multimodal

Example Response#

{  "object": "list",  "data": [    {      "id": "claude-sonnet-4-5",      "object": "model",      "created": 1747180800,      "owned_by": "anthropic"    },    {      "id": "gpt-4o",      "object": "model",      "created": 1715558400,      "owned_by": "openai"    },    {      "id": "gemini-1.5-pro",      "object": "model",      "created": 1704067200,      "owned_by": "google"    },    ...  ]}
