Deep dive

On shared benchmark coverage, Google-Proof Q&A has Hunyuan Hy3 Preview at 87.2 and Phi-4 14B at 56.1, with Hunyuan Hy3 Preview ahead by 31.1 points. The largest visible gap is 31.1 points on Google-Proof Q&A, 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, and structured outputs: Phi-4 14B. 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, Hunyuan Hy3 Preview lists $0.07/1M input and $0.26/1M output tokens on the cheapest tracked provider, while Phi-4 14B lists $0.07/1M input and $0.14/1M output tokens on the cheapest tracked provider. A 70/30 input-output blend puts Phi-4 14B lower by about $0.04 per million blended tokens. Availability is 2 providers versus 3, so concentration risk also matters.

Choose Hunyuan Hy3 Preview when reasoning depth and larger context windows are central to the workload. Choose Phi-4 14B when provider fit, lower input-token cost, and broader provider choice are more important. For production, rerun your own prompts through the exact provider, region, and tool stack you plan to ship.
