Grok 3 Mini
Lightweight reasoning model from xAI with configurable thinking effort, released February 2025.
About
Grok 3 Mini is xAI's streamlined version of Grok 3, released February 19, 2025 alongside the Grok 3 API. It is built for logic-based tasks that do not require deep domain knowledge, with reasoning traces exposed and a reasoning_effort parameter that lets callers choose between low (fast) and high (deep thinking) modes.
On the API it carries a 131K token context window and accepts text and image input with function calling and structured outputs. Pricing sits at $0.30 per million input tokens and $0.50 per million output tokens, positioning it as xAI's cost-effective reasoning tier; a faster-served variant trades higher prices for lower latency.
