Notes

This client uses the OpenAI-compatible protocol. The three settings are always the same: Base URL = https://llmapi.pro/v1, API Key = your sk-... key, and type the model name manually (we recommend claude-opus-4-8).

Client not listed? Any "OpenAI-compatible" app works: Base URL = https://llmapi.pro/v1, key = your sk-..., type the model name. Or email [email protected].
