Copy the exact model ID from the subscription model list or pay-as-you-go channels, and check that your client protocol supports it. The model catalogue labels each model’s billing mode.
A monthly subscription uses a subscription key, with supported models sharing the plan quota. Pay-as-you-go API billing uses a separate key and balance. Select the matching key type in the Console, then configure your client protocol. Topping up API credit does not increase subscription quota.
Setup steps
- Open Settings → Model providers and add an OpenAI-compatible (Custom) provider.
- Base URL =
https://llmapi.pro/v1, API Key = yoursk-.... - 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 = yoursk-...key, and type the model name manually (we recommendclaude-opus-5). - 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 =
