Composer 2 vs Grok 4

Side-by-side benchmark comparison across agentic, coding, multimodal, knowledge, reasoning, and math workflows.

Grok 4 is clearly ahead on the aggregate, 67 to 62. The gap is large enough that you do not need to squint at the spreadsheet to see the difference.

Composer 2 is the reasoning model in the pair, while Grok 4 is not. That usually helps on harder chain-of-thought-heavy tests, but it can also mean more latency and more token spend in real use. Composer 2 gives you the larger context window at 200K, compared with 128K for Grok 4.

Quick Verdict

Pick Grok 4 if you want the stronger benchmark profile. Composer 2 only becomes the better choice if agentic is the priority or you need the larger 200K context window.
