How do I switch the AI provider and model in V5's AI settings, and make the settings take effect?

1. Go to the "AI Settings" page in V5. 2. In "AI Provider", choose the provider you want to use. Claude and ChatGPT are available. 3. In "Claude Model", choose a model. Currently Claude Sonnet 5 and Claude Haiku 4.5 are available. 4. Enter the "API Key". 5. Click "Update Settings".

Note: saving the upstream settings is the same as enabling them, and the provider and model must be submitted together. Changing only the dropdown will not take effect, so you must click "Update Settings". If you want to turn AI off later, click "Disable".
