Deep dive
The capability footprint differs most on multimodal input: Grok 4.1, reasoning mode: Tencent Hy3 Preview, function calling: Tencent Hy3 Preview, and tool use: Tencent Hy3 Preview. 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.
Pricing coverage is uneven: Grok 4.1 has no token price sourced yet and Tencent Hy3 Preview has no token price sourced yet. Provider availability is 0 tracked routes versus 1. Treat unknown pricing as an integration gap, then verify the route you will actually call before estimating production spend.
Choose Grok 4.1 when long-context analysis and larger context windows are central to the workload. Choose Tencent Hy3 Preview when reasoning depth 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. This keeps the decision grounded in measurable tradeoffs instead of brand-level assumptions. It also helps separate model capability from provider packaging, which can change cost and latency.
FAQ
Which has a larger context window, Grok 4.1 or Tencent Hy3 Preview?
