Grok 4.20 Non-Reasoning

by xAI

Grok 4.20 Non-Reasoning is the speed-optimized production variant of xAI's March 2026 Grok 4.20 generation, returning direct answers without extended reasoning. It keeps a 2 million token context window and real-time integration with X data, enabling applications that need current information and low latency. The model supports native tool use, structured outputs, and image input across multimodal requests. Without the reasoning overhead of the chain-of-thought variants, the non-reasoning mode prioritizes response speed, reported at around 232 tokens per second output and roughly half-a-second time-to-first-token, making it a fit for interactive systems, support, and content generation. Released in March 2026, Grok 4.20 Non-Reasoning is xAI's high-throughput path for the 4.20 generation when you need capability, long context, and real-time grounding without the latency of reasoning steps.
