Comparison summary
How to judge first
StepFun AI and Tencent Hunyuan are both on the China route, so compare protocol, model coverage, and key visibility.
When model coverage is close, move the decision to price, rate limits, interface compatibility, and stability.
In production, one key should reveal provider identity, callable models, balance or quota signals, limits, and risk notes.
Key checking value
A key may expose only part of the models, interfaces, or regions, so the final call must rely on detection results, not the catalog alone.

Procurement and distribution
For procurement, agency, and marketplace listing, provider comparison must end in supply stability, pricing, monitoring, and model updates.
- Do not treat catalog coverage as real sellability.
- Key checking and continuous monitoring are the final commercial loop.
