Model providers
The AI features of Locus use a model from a provider of your choice, with your own API key. You pay the provider for what you use. Locus itself does not charge anything.
Setting up AI
Section titled “Setting up AI”- Open Settings > AI features > General.
- Click Set up AI.
- Choose a provider.
- Paste your API key and click Next. Locus checks that the key works before it saves it.
- Choose a model and click Use this model.
The AI sidebar and natural language input then use this model. You can change the model later under AI sidebar.
