Grok 4.20 0309 (Non-reasoning)
Analysis Summary
Grok 4.20 0309 Non-reasoning is xAI's faster-style variant released in March 2026, with an intelligence index of 22.9 and pricing of 2 for input and 6 for output. The lower measured reasoning result distinguishes it from the reasoning version and limits confidence on difficult analysis, technical problem solving, and nuanced instruction following.
It can serve high-volume drafting, rewriting, categorisation, SEO metadata, and other templated workloads where a reviewer or deterministic process catches errors. It is not the right choice for complex strategy, production code, long-form research, or autonomous agents based on the data provided. The price makes it a useful volume tier, but the reasoning variant is the better default when task difficulty rises.
