Deep dive
The capability footprint differs most on reasoning mode: GPT-5.2 Codex, structured outputs: Gemini 2.5 Pro Computer Use Preview, and code execution: GPT-5.2 Codex. 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 GPT-5.2 Codex lists $1.75/1M input and $14/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Gemini 2.5 Pro Computer Use Preview lower by about $1.55 per million blended tokens. Availability is 2 providers versus 1, so concentration risk also matters.
Choose Gemini 2.5 Pro Computer Use Preview when vision-heavy evaluation, lower input-token cost, and broader provider choice are central to the workload. Choose GPT-5.2 Codex when coding workflow support are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
