GPT-5.4 wins on coding benchmarks and has unique desktop computer-use capabilities, and it is also cheaper per input token ($2.50 vs $3) with a slightly larger window (272K vs Grok 4's 256K). Grok 4's distinctive edge was real-time X data. xAI retired Grok 4 from its API on May 15, 2026 — for a current decision, compare GPT-6.1 Sol with Grok 4.7.

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 ContextGPT-5.4 wins
GPT-5.4 has the slightly larger window: 272K tokens against Grok 4's 256K. Earlier versions of this page said Grok 4 had 2M; that was wrong.
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.
PriceGPT-5.4 wins
GPT-5.4 is slightly cheaper on input ($2.50 vs Grok 4's $3/1M); both cost $15/1M output.
Which should you pick?
Pick Grok 4 if…
You need to analyze very large documents or codebases exceeding 272K tokens
Real-time X/Twitter or social media data is relevant to your research
Output token volume is high and you want to save on output costs
You're on X Premium and want a native Grok integration
xAI's July 2025 flagship, priced at $3/$15 per million tokens with a 256K context window. Retired from xAI's API on May 15, 2026; current Grok models are Grok 4.6 and Grok 4.7.

What people actually use it for
Early-stage research mapping — exploring a new topic before narrowing down
Analyzing codebases and datasets within a 256K-token context window
Competitive intelligence and market research with broad, fast synthesis
Where it wins
Strong coding and reasoning at its July 2025 launch
256K-token context window
Fast and responsive for exploration and open-ended research loops
Where it falls down
Retired from xAI's API on May 15, 2026
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
Retired: xAI shut down the grok-4-0709 API on May 15, 2026. It was a strong coding model at launch, at $3/$15 with a 256K window; earlier versions of this page listed $2/$6 and 2M tokens in error. Use Grok 4.7 instead.

What people actually use it for
Building agents that browse the web and operate desktop software autonomously via the API
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
Newer models — Claude Opus 5.5, GPT-6.1 Sol — outperform it on coding benchmarks
Smaller context window (272K) than current 1M-token models
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
Still capable for desktop automation at its $2.50/$15 price, but superseded: GPT-6.1 Sol is stronger at $2/$10, and Claude Opus 5.5 leads coding.
