Deep dive

The capability footprint differs most on function calling: GPT-4 Turbo, tool use: GPT-4 Turbo, and code execution: GPT-4 Turbo. Both models share vision, multimodal input, and 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, GPT-4 Turbo lists $5/1M input and $15/1M output tokens on the cheapest tracked provider, while Mistral Small 3.1 24B Instruct lists $0.10/1M input and $0.30/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Mistral Small 3.1 24B Instruct lower by about $7.84 per million blended tokens. Availability is 6 providers versus 6, so concentration risk also matters.

Choose GPT-4 Turbo when coding workflow support are central to the workload. Choose Mistral Small 3.1 24B Instruct when vision-heavy evaluation 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.

FAQ

Which has a larger context window, GPT-4 Turbo or Mistral Small 3.1 24B Instruct?
