Grok 4.6 Early Hands-on: Fast, Smarter, Strong Value

Grok 4.6 has quickly drawn hands-on reviews from developers, with consensus around three points: fast responses, noticeably smarter behavior, and strong value.

Confirmed

• A user who exhausted a Codex $100 plan (retweeted by @elonmusk) called Grok 4.6 + Grok Build the best recent experience: speed on par with 4.5 but smarter, with far less waiting and context-switching, enough to consider dropping Codex
• @doodlestein reported that under the $300/month Grok SuperHeavy plan, Grok 4.6 with the grok build harness handles all Git commits and other tasks fast with no dangerous behavior
• @prasenx, after five days, noted big gains in speed and comprehension for front-end and daily coding with low quota usage and few loops, though three.js 3D work still trails Opus
• @doodlestein also described a multi-model workflow: Fable xhigh (medium for minor tasks) with Claude Code, Sol xhigh with Codex, plus a Sol xhigh controlling a Terra swarm; he now trusts Gemini 3.7 Flash for web front-end and secondary tasks, and rates Kimi K3 ($200/month) with OMP as excellent value

Why it matters

First-hand reports suggest the coding-model landscape is shifting: Grok 4.6's speed and pricing give Codex users a real alternative, while developers increasingly mix models by task type to optimize cost and capability.
