What people actually use it for

  • Early-stage research mapping — exploring a new topic before narrowing down
  • Analyzing large codebases or datasets within a 2M-token context window
  • Competitive intelligence and market research with broad, fast synthesis

Where it wins

  • 75% SWE-bench score — strong coding performance close to top Claude models
  • 2M token context window at $2/$6 per million tokens
  • Fast and responsive for exploration and open-ended research loops

Where it falls down

  • Claude Opus 4.6 and Sonnet 4.6 lead on pure coding benchmarks
  • Less established ecosystem and tooling than OpenAI or Anthropic

Skip it if

You need the highest writing quality or the most reliable production-grade output — Claude wins both.

Our verdict

Strong coding benchmark with excellent value. The $2/$6 pricing and 2M context make it competitive with more expensive alternatives.

FAQ

Is GPT-4o better than Grok 4?

Grok 4 wins on more of the categories we score — coding, research, reasoning — so it is the better default of the two. GPT-4o is the better pick when your work is mostly multimodal tasks and image-adjacent workflows. Neither is universally "better": Grok 4 is aimed at coding and research at competitive pricing with maximum context, GPT-4o at multimodal tasks and image-adjacent workflows.

Which is cheaper — GPT-4o or Grok 4?

Grok 4 is cheaper at $2/1M input and $6/1M output. GPT-4o costs $2.5/1M input and $10/1M output.

Which has a larger context window — GPT-4o or Grok 4?

Grok 4 has the larger context window at 2M tokens vs GPT-4o's 128K. For large document analysis, Grok 4 is the stronger pick.

Is GPT-4o or Grok 4 better for coding?

Grok 4 is better for coding with a score of 92 vs GPT-4o's 58 (out of 100). GPT-6 Astra is the overall coding leader in this directory at 100/100.

Which is faster — GPT-4o or Grok 4?

Both GPT-4o and Grok 4 have similar speed profiles — rated fast. Neither will be the bottleneck if latency is your deciding factor.

What are the downsides of Grok 4?

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 GPT-4o instead.

What are the downsides of GPT-4o?

Outclassed by newer models on pure coding and reasoning. Gemini 3.1 Pro now handles multimodal at a lower price. Avoid it if you need the latest reasoning or coding performance — GPT-5.4 replaces it for serious work. Against Grok 4 specifically, the gap shows up most on coding (92 vs 58).

What does a month of real work cost on GPT-4o vs Grok 4?

Take a moderate workload of 10M input and 2M output tokens a month. GPT-4o runs $45.00 (at $2.5/1M in and $10/1M out); Grok 4 runs $32.00 (at $2/1M in and $6/1M out). That is a $13.00/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.

Can I use GPT-4o and Grok 4 together?

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 GPT-4o handling multimodal tasks and image-adjacent workflows. Since Grok 4 is both the stronger and the cheaper option here, a split mainly makes sense if GPT-4o covers a capability you specifically need.
