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.

How they compare
Which model wins for each use case — and why.
CodingGPT-5.4 wins
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.
Long ContextGrok 4 wins
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.
Real-time DataGrok 4 wins
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.
Agentic TasksGPT-5.4 wins
GPT-5.4 is the only frontier model with desktop computer-use via API — clicking, typing, and navigating software autonomously.
PriceGrok 4 wins
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.
Which should you pick?
Pick Grok 4 if…

Complex multi-step reasoning for financial modeling and decision analysis
Autonomous test-run-debug loops for coding with computer-use control
Where it wins
Only frontier model that can control a desktop via API (click, type, navigate)
Strong at multi-step agentic tasks and autonomous workflows
Competitive coding performance with 74.9% SWE-bench score
Where it falls down
Claude Opus 4.7 and GPT-5.5 now outperform it on current premium coding benchmarks
Smaller context window (272K) vs Gemini 3.1 Pro (2M) for research
Skip it if
You need the highest current coding benchmark scores — Claude Opus 4.7 and GPT-5.5 are newer premium picks.
Our verdict
Best choice when you need a model that can operate software autonomously at the older GPT-5.4 price tier. For current premium coding quality, Claude Opus 4.7 leads.
