Deep dive
The capability footprint differs most on structured outputs: Grok Build 0.1. 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, Grok Build 0.1 lists tiered pricing: 0-200,001t is $1/1M input and $2/1M output; 200,001t+ is $2/1M input and $4/1M output, while Tencent 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 Tencent Hy3 Preview lower by about $1.18 per million blended tokens. For tiered rows, this cheapest-track view can understate interactive or fast-lane spend, so compare the tier you will actually use. Availability is 2 providers versus 1, so concentration risk also matters.
Choose Grok Build 0.1 when coding workflow support and broader provider choice are central to the workload. Choose Tencent Hy3 Preview when long-context analysis, 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.
