About this model

GPT-4o mini (“o” for “omni”) is a fast, affordable small model for focused tasks. It accepts both text and image inputs, and produces text outputs (including Structured Outputs). It is ideal for fine-tuning, and model outputs from a larger model like GPT-4o can be distilled to GPT-4o-mini to produce similar results at lower cost and latency.

Best suited for

High-volume chatbots, customer support, fast responses, simple summarization, function calling, and cost-efficient everyday AI tasks.

Built-in tools

Gtwy web search

Hosted by the gateway — enable them per request without wiring your own endpoint.

Capabilities

Vision

Accepts images alongside text in the same message.

Files

Accepts file attachments — PDFs, transcripts, spreadsheets.

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_level

Controls 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 Limit

Specifies the maximum number of text units (tokens) allowed in a response, limiting its length.

tools

Lists tool definitions or capabilities available to the model.

tool_choice

Decides whether to use tools or just the model for generating responses.

response_type

Defines the format or type of the generated response.

parallel_tool_calls

Enables parallel execution of tools, allowing multiple tools to run simultaneously.

stream

Sends the response in real-time as it's being generated.
