About this model
GPT-4o ("o" for "omni") is a fast, general-purpose multimodal model. It accepts both text and image inputs, and produces text outputs.
Best suited for
- Multimodal assistants, real-time voice/vision use cases, interactive AI features, complex content creation, and rich user-facing applications.
Built-in tools
Hosted by the gateway — enable them per request without wiring your own endpoint.
Capabilities
Vision
Accepts images alongside text in the same message.
Tools
Native function calling, so agents can invoke your endpoints.
System prompt
Honours a dedicated system role, separate from the user turn.
Supported parameters
creativity_levelControls the creativity of responses. Higher values (e.g., 0.7) increase creativity; lower values (e.g., 0.2) make responses more predictable.
max_tokensMax Tokens LimitSpecifies the maximum number of text units (tokens) allowed in a response, limiting its length.
toolsLists tool definitions or capabilities available to the model.
tool_choiceDecides whether to use tools or just the model for generating responses.
response_typeDefines the format or type of the generated response.
parallel_tool_callsEnables parallel execution of tools, allowing multiple tools to run simultaneously.
streamSends the response in real-time as it's being generated.
service_tiertemperatureUse this model
OpenAI-SDK compatible, with gateway fallback and routing across providers.
