Deep dive
The capability footprint differs most on function calling: Together AI - Mistral Small 3, tool use: Together AI - Mistral Small 3, and structured outputs: Together AI - Mistral Small 3. Both models share the core language-model surface, 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, GPT-4o Audio lists $2.5/1M 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 $4.59 per million blended tokens. Availability is 1 providers versus 1, so concentration risk also matters.
Choose GPT-4o Audio 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.
