[Provider] Lower-cost DeepSeek/Kimi/GLM endpoint for testing

[jasonwhite661]

Hi,

I noticed CC-RouterMultiProvider and that users care about cost-optimized routing across GLM/DeepSeek/MiniMax/Claude.

I'm testing a lower-cost China-model API (DeepSeek / Kimi / GLM / Qwen) via an Anthropic/OpenAI-compatible endpoint.

Would you be open to an optional backend for testing? I'll provide free test credits and a price/latency comparison vs OpenRouter — no architecture change.

Which backend do your users use most today?

Thanks.
