Recommended

claude-opus-4-8 · claude-sonnet-4-6 · claude-haiku-4-5

Setup steps

Open Settings → Model providers and add an OpenAI-compatible (Custom) provider.
Base URL = https://llmapi.pro/v1, API Key = your sk-....
Set the model to claude-opus-4-8, save, and select it in the model picker.

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).
The entry may live under "Bring your own key / custom model" — just pick OpenAI-compatible. If only the native Gemini protocol is offered, use its OpenAI-compatible entry.

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].
