Grok-4

Three models dominate the 2026 AI coding conversation, and none of them is universally best. Claude Opus 4 leads SWE-bench Verified, Grok 4 holds an edge on Terminal-Bench 2.0 shell tasks, and Gemini 2.5 Pro pairs a 1M-token context window with the lowest price of the three at $25/month. Picking the wrong one means paying for context you never use or choosing speed over correctness on a production codebase. This comparison cuts through the benchmark noise and maps each model to the workflows where it actually earns its subscription. ...

A Grok 4 review in an older search result can describe a model different from the one an API request serves today. Before comparing quality or cost, establish the exact model identifier, whether it is an alias and which release the evidence describes. This review checks release and migration documentation. It is not an independent performance benchmark. The previous cross-vendor score table had no reproducible evaluation source and has been removed. ...
