Deep dive
The capability footprint differs most on function calling: Together AI - Mistral Small 3 and tool use: Together AI - Mistral Small 3. 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 Preview 05-06 lists $1.25/1M input and $10/1M output tokens, while Together AI - Mistral Small 3 lists $0.1/1M input and $0.3/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Together AI - Mistral Small 3 lower by about $3.71 per million blended tokens. Availability is 1 providers versus 1, so concentration risk also matters.
Choose Gemini 2.5 Pro Preview 05-06 when long-context analysis and larger context windows are central to the workload. Choose Together AI - Mistral Small 3 when provider fit 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. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions.
