Grok 4 wins on more of the categories we score — coding, research, reasoning — so it is the better default of the two. Claude Sonnet 4.6 is the better pick when your work is mostly daily coding and writing. Neither is universally "better": Grok 4 is aimed at coding and research at competitive pricing with maximum context, Claude Sonnet 4.6 at daily coding and writing.
Grok 4 is cheaper at $2/1M input and $6/1M output. Claude Sonnet 4.6 costs $3/1M input and $15/1M output.
Grok 4 has the larger context window at 2M tokens vs Claude Sonnet 4.6's 1M. For large document analysis, Grok 4 is the stronger pick.
Claude Sonnet 4.6 is better for coding with a score of 97 vs Grok 4's 92 (out of 100). GPT-6 Astra is the overall coding leader in this directory at 100/100.
Grok 4 is faster with a fast speed rating (score: 4) vs Claude Sonnet 4.6's balanced rating (score: 3). Speed matters most for interactive and high-throughput work; for batch jobs the Claude Sonnet 4.6 latency penalty is usually invisible.
Claude Opus 4.6 and Sonnet 4.6 lead on pure coding benchmarks. Less established ecosystem and tooling than OpenAI or Anthropic. Avoid it if you need the highest writing quality or the most reliable production-grade output — Claude wins both. That is the main case for looking at Claude Sonnet 4.6 instead.
Claude Opus 4.7 has a higher current premium coding ceiling. GPT-5.5 or GPT-5.4 are better picks when OpenAI computer-use workflows are the priority. Avoid it if you specifically need desktop-control capabilities (GPT-5.5/GPT-5.4) or the absolute highest coding ceiling (Opus 4.7). Against Grok 4 specifically, the gap shows up most on coding (92 vs 97).
Take a moderate workload of 10M input and 2M output tokens a month. Grok 4 runs $32.00 (at $2/1M in and $6/1M out); Claude Sonnet 4.6 runs $60.00 (at $3/1M in and $15/1M out). That is a $28.00/month difference — Grok 4 is the cheaper of the two at this volume, and the gap scales linearly as you send more. Output tokens dominate the bill on both, so prompt length matters far less than response length.
Yes, and for most teams that beats picking one. A common split is Grok 4 for coding and research at competitive pricing with maximum context, with Claude Sonnet 4.6 handling daily coding and writing. Since Grok 4 is both the stronger and the cheaper option here, a split mainly makes sense if Claude Sonnet 4.6 covers a capability you specifically need.
