Deep dive
The capability footprint differs most on reasoning mode: Hunyuan Hy3 Preview, function calling: Hunyuan Hy3 Preview, and tool use: Hunyuan 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: Hunyuan Hy3 Preview has $0.07/1M input tokens and Marin 32B Base has no token price sourced yet. Provider availability is 2 tracked routes versus 0. Treat unknown pricing as an integration gap, then verify the route you will actually call before estimating production spend.
Choose Hunyuan Hy3 Preview when reasoning depth, larger context windows, and broader provider choice are central to the workload. Choose Marin 32B Base when provider fit 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, Hunyuan Hy3 Preview or Marin 32B Base?
Hunyuan Hy3 Preview supports 262k tokens, while Marin 32B Base supports 4k tokens. That gap matters most for long documents, large codebases, retrieval-heavy agents, and conversations where earlier context must remain visible.
