Analysis Summary
Grok 4.20 0309 (Non-reasoning) is the standard inference mode of xAI's Grok 4.20 model, released March 2026. With an intelligence index of 22.5 and an agentic index of 45.8, it occupies a solid mid-tier position. GPQA of 0.785 and HLE of 0.225 indicate strong general knowledge, and its tau2 score of 0.696 reflects reliable task completion on complex benchmarks.
For businesses, this model is well-suited to agentic automation, tool-use pipelines, and structured workflows where the full reasoning overhead is not required. Its instruction-following score of 0.478 is moderate, and long-context reasoning at 0.18 is limited, so it is less suited to document-heavy or precision-content tasks. The terminal benchmark score of 0.220 suggests adequate but not exceptional coding support.
At $2 input and $6 output per million tokens, it offers reasonable value for its agentic capability tier. Teams that need reliable tool-use and multi-step automation without the latency of a full reasoning model will find this a practical deployment option, particularly when paired with the reasoning variant for more demanding tasks.
