About this model
GPT-6 Luna is OpenAI's most efficient GPT-6 model, built for high-volume tasks. 1,050,000-token context window with 128,000 max output tokens and reasoning effort control.
Best suited for
- High-volume and latency-sensitive tasks, classification, summarization, lightweight agentic workflows, and cost-sensitive general-purpose use.
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.
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.
Reasoning
Emits a separate thinking pass before the answer.
Supported parameters
max_tokensMax Tokens LimitSpecifies the maximum number of text units (tokens) allowed in a response, limiting its length.
parallel_tool_callsEnables parallel execution of tools, allowing multiple tools to run simultaneously.
reasoningControls the level of reasoning used by the model.
response_typeDefines the format or type of the generated response.
service_tierstreamSends the response in real-time as it's being generated.
tool_choiceDecides whether to use tools or just the model for generating responses.
toolsLists tool definitions or capabilities available to the model.
Use this model
OpenAI-SDK compatible, with gateway fallback and routing across providers.
