Advanced Reasoning Features

The Grok 3 Mini variants include dedicated reasoning functionality, enabling them to process information before generating responses—especially valuable for intricate problem-solving scenarios.

Models with Reasoning Support

Reasoning functionality is exclusively available in:

• grok-3-mini-beta
• grok-3-mini-fast-beta

Note that grok-3-beta and grok-3-fast-beta do not include reasoning support.

Adjusting Reasoning Intensity

For models that support reasoning, you can regulate the depth of analysis using the reasoning_effort parameter:

• low: Reduced processing time, consuming fewer tokens for faster results
• high: Extended analysis period, utilizing additional tokens for intricate challenges

Select low for straightforward questions requiring rapid completion, and high for challenging problems where processing time is less critical.

Core Capabilities

• Methodical Problem Analysis: The model systematically evaluates problems before formulating responses
• Mathematical & Analytical Proficiency: Demonstrates excellence in computational tasks and logical reasoning
• Thought Process Visibility: Access to the model's reasoning workflow via the reasoning_content field in response completion objects

Important Considerations

• Context Capacity: The majority of Grok models provide generous context windows (extending to 131K tokens), enabling you to supply extensive code samples and contextual information in your requests.
• Image Processing: Opt for vision-compatible models (grok-2-vision-latest, grok-2-vision, etc.) when working with visual content or image analysis tasks.
• Cost Structure: Model pricing differs, with input rates spanning $0.3 to $5.0 per million tokens and output rates ranging from $0.5 to $25.0 per million tokens. Consult xAI documentation for current pricing details.
• Speed vs. Capability Balance: "Fast" model variants generally deliver speedier responses but might incur elevated costs, whereas "mini" variants provide cost efficiency with potentially limited functionality.
