Deep dive

The capability footprint differs most on vision: Gemini 2.5 Pro Computer Use Preview, multimodal input: Gemini 2.5 Pro Computer Use Preview, reasoning mode: Grok-2, function calling: Gemini 2.5 Pro Computer Use Preview, and tool use: Gemini 2.5 Pro Computer Use Preview. Both models share structured outputs, so the practical split is not just feature count. Use those differences to decide whether the page is about raw model quality, agentic coding support, multimodal ingestion, or predictable structured API behavior.

For cost, Gemini 2.5 Pro Computer Use Preview lists $1.25/1M input and $10/1M output tokens on the cheapest tracked provider, while Grok-2 lists $0.50/1M input and $0.50/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Grok-2 lower by about $3.38 per million blended tokens. Availability is 2 providers versus 1, so concentration risk also matters.

Choose Gemini 2.5 Pro Computer Use Preview when long-context analysis, larger context windows, and broader provider choice are central to the workload. Choose Grok-2 when reasoning depth and lower input-token cost are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.

FAQ

Which has a larger context window, Gemini 2.5 Pro Computer Use Preview or Grok-2?

Gemini 2.5 Pro Computer Use Preview supports 1.05m tokens, while Grok-2 supports 128k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
