The Default model
On Models, the Default pill marks the model new agents start with. The first model you add is that model.
Open Connections, then Model providers, then the Models tab. The section is Which models agents may use. The line under it is Agents choose from these models.
The Default pill
The model new agents start with has a Default pill beside its name. Voice and transcription rows do not use this pill.
When the company has not chosen models yet, the page says This company hasn't chosen its models yet. Add the models your agents may use; the first one you add is the default for new agents. Add it from Add models.
On Add models, that model's row says The default for new agents while the model is still listed there. After you add it, the Default pill is on Models.
