Route difference
The first layer is not brand size. It is user market, protocol entry, model-family coverage, and real call stability.
- DeepSeek: China route, 11 Models
- NVIDIA: global route, 11 Models

DeepSeek vs NVIDIA
Start with the provider route, compare model coverage, then use read-only key checking to verify what is actually callable.

Comparison summary
How to judge first
DeepSeek and NVIDIA are cross-region routes. Start with the user's market, then verify whether the key can call reliably across regions.
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.
