Deep dive
The capability footprint differs most on vision: Gemini 2.0 Flash, multimodal input: Gemini 2.0 Flash, reasoning mode: Gemini 2.0 Flash, function calling: Gemini 2.0 Flash, tool use: Gemini 2.0 Flash, and code execution: Gemini 2.0 Flash. 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 2.0 Flash lists $0.10/1M input and $0.40/1M output tokens on the cheapest tracked provider, while GPT-4o-mini Search Preview lists $0.15/1M input and $0.60/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Gemini 2.0 Flash lower by about $0.09 per million blended tokens. Availability is 4 providers versus 2, so concentration risk also matters.
Choose Gemini 2.0 Flash when coding workflow support, larger context windows, and lower input-token cost are central to the workload. Choose GPT-4o-mini Search Preview when provider fit are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
