Deep dive
The capability footprint differs most on reasoning mode: Grok-3. Both models share vision, multimodal input, function calling, and tool use, 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-3 lists $0.80/1M input and $2.40/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Grok-3 lower by about $2.60 per million blended tokens. Availability is 2 providers versus 4, so concentration risk also matters.
Choose Gemini 2.5 Pro Computer Use Preview when long-context analysis and larger context windows are central to the workload. Choose Grok-3 when reasoning depth, lower input-token cost, and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions. It also helps separate model capability from provider packaging, which can change cost and latency.
