Head-to-head · Updated March 2026
Grok 4 and GPT-5.4 are both positioned as capable, mid-tier premium models but they have a clear difference: GPT-5.4 wins on coding benchmarks and has unique desktop computer-use capabilities. Grok 4 counters with a 2M token context window (7× GPT-5.4's 272K), real-time X/Twitter data access, and lower pricing at $2 vs $2.50/1M input. The decision hinges on use case: agentic automation and coding go to GPT-5.4; large-context research and real-time data go to Grok 4.
Grok 4
Strong coding value with 2M context — an underrated pick at this price.
GPT-5.4
Best for agentic automation and desktop control workflows.
| Grok 4 | GPT-5.4 | |
|---|---|---|
| Input cost / 1M tokens | $$2.00/1M | $$2.50/1M |
| Output cost / 1M tokens | $$6.00/1M | $$15.00/1M |
| Context window | 2M tokens | 272k tokens |
| Speed | Fast | Balanced |
| Price tier | Balanced | Premium |
Which model wins for each use case — and why.
GPT-5.4 scores 74.9% on SWE-bench and has desktop computer-use for agentic coding. Grok 4 handles code well but trails on the key benchmarks.
Grok 4 has a 2M token context window vs GPT-5.4's 272K — more than 7× larger. For large document analysis, Grok 4 has a significant capacity advantage.
Grok 4 has exclusive access to real-time X/Twitter data. GPT-5.4 uses Bing but doesn't have native social media data access.
GPT-5.4 is the only frontier model with desktop computer-use via API — clicking, typing, and navigating software autonomously.
Grok 4 costs $2/1M input vs GPT-5.4's $2.50/1M, and $6 vs $15/1M output. Grok 4 is significantly cheaper on output tokens.
