About this model

Non-reasoning variant of xAI's Grok 4.20 (0309) model, for low-latency chat, tool calling and instruction following without a reasoning pass.

Best suited for

Low-latency chat
Agentic tool calling
Instruction following

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.

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.

parallel_tool_calls

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

response_type

Defines the format or type of the generated response.

stream

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

tool_choice

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

tools

Lists tool definitions or capabilities available to the model.

Use this model

OpenAI-SDK compatible, with gateway fallback and routing across providers.
