## About gemini-2.5-pro-preview

Gemini 2.5 Pro is Google's mature long-context multimodal reasoning model for complex code, research, and media understanding that benefits from a stable version.

### Best for

Large repositories, scientific and business analysis, video and audio understanding, and production projects that value mature ecosystem compatibility.

### Core strengths

- A 1M context window and 64K output cover large evidence sets.
- Natively supports text, image, audio, video, and PDFs.
- Function calling, structured output, and the Google tool ecosystem are mature.

### Limitations

- Newer Gemini 3.x models generally improve capability or efficiency.
- Long media and high thinking budgets increase latency and token use.

### Selection and production evaluation

Start a gemini-2.5-pro-preview evaluation by mapping its official positioning to real work: Large repositories, scientific and business analysis, video and audio understanding, and production projects that value mature ecosystem compatibility. The first pass should exercise both its main strength, "A 1M context window and 64K output cover large evidence sets.", and its known limitation, "Newer Gemini 3.x models generally improve capability or efficiency.", instead of relying on a single subjective general-chat comparison.

For access, MoleAPI currently lists openai protocols and the Standard billing groups for this Google model; the default price summary is Input $1.25 / 1M tokens · Output $10 / 1M tokens. Pricing, protocols, and groups come from the live catalog, so production planning should still price representative requests using real context length, output size, and cache-hit assumptions.

No independent ranking is shown unless it matches this exact model ID and reasoning profile, so nearby variants are not used as a proxy. Before launch, pin the model ID, prompt, and sample set, then compare task accuracy, structured-output validity, tool-call success, and timeout rates under the same conditions.

The model material on this page was last checked on 2026-07-24. When upstream model cards, context limits, or tool support change, update the cited bilingual facts before changing the recommendation; live MoleAPI price changes remain separate and update from the catalog automatically.
