Deep dive
The capability footprint differs most on vision: o3 Deep Research, multimodal input: o3 Deep Research, and structured outputs: o3 Deep Research. Both models share reasoning mode, function calling, and tool use, 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, Hunyuan Hy3 Preview lists $0.07/1M input and $0.26/1M output tokens on the cheapest tracked provider, while o3 Deep Research lists $10/1M input and $40/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Hunyuan Hy3 Preview lower by about $18.88 per million blended tokens. Availability is 2 providers versus 1, so concentration risk also matters.
Choose Hunyuan Hy3 Preview when long-context analysis, larger context windows, and lower input-token cost are central to the workload. Choose o3 Deep Research when vision-heavy evaluation 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
