Grok 4.20 (non-reasoning) · impossibl

Grok 4.20 (non-reasoning) is the non-reasoning snapshot of xAI's Grok 4.20, built for fast, precise responses with agentic tool calling and strict prompt adherence. It shares the reasoning variant's text and image inputs, function calling, and structured outputs, but skips extended reasoning for lower latency.
