About this model
Grok 4.6 is xAI's frontier model for coding, agentic tasks, and knowledge work, built on Grok 4.5 with a focus on long-running agents, agentic coding, and interactive/visual work. Accepts text and image input, produces text output, and supports low/medium/high/xhigh reasoning effort. Pricing shown is for the base tier (below 200K input tokens); usage at or above 200K tokens is billed at $4 input / $1 cached / $12 output per 1M tokens.
Best suited for
- Long-running agentic workflows
- Agentic coding
- Visual and interactive tasks
- General chat and coding tasks
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
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.
reasoningReasoning EffortControls the depth of reasoning the model performs before responding.
Use this model
OpenAI-SDK compatible, with gateway fallback and routing across providers.
