Deep dive

On shared benchmark coverage, SWE-bench Verified has DeepSeek V3.2 at 70 and Hunyuan Hy3 Preview at 74.4, with Hunyuan Hy3 Preview ahead by 4.4 points; Google-Proof Q&A has DeepSeek V3.2 at 84 and Hunyuan Hy3 Preview at 87.2, with Hunyuan Hy3 Preview ahead by 3.2 points. The largest visible gap is 4.4 points on SWE-bench Verified, which matters most when that benchmark mirrors your workload. Treat isolated benchmark wins as directional, because provider routing, prompt style, and tool access can move real application results.

The capability footprint differs most on reasoning mode: Hunyuan Hy3 Preview, function calling: Hunyuan Hy3 Preview, tool use: Hunyuan Hy3 Preview, structured outputs: DeepSeek V3.2, and code execution: DeepSeek V3.2. 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, DeepSeek V3.2 lists $0.25/1M input and $0.38/1M output tokens on the cheapest tracked provider, while Hunyuan Hy3 Preview lists $0.07/1M input and $0.26/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Hunyuan Hy3 Preview lower by about $0.17 per million blended tokens. Availability is 7 providers versus 2, so concentration risk also matters.

Choose DeepSeek V3.2 when coding workflow support and broader provider choice are central to the workload. Choose Hunyuan Hy3 Preview when reasoning depth, larger context windows, 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.
