Adding a key
In Models, find the provider, paste its API key and tap Test and save. The key is tested before being saved and stored encrypted; afterwards only its ending shows («Key ending in …»).
Each provider has three tiers: the most capable (complex cases, several tools), fast and capable (most conversations) and the cheapest (simple questions and high volume). Each agent’s model is picked on its Model tab: see Agents.
A key’s status
If the chosen model isn’t enabled for your key, the console won’t let you publish the agent with that model: enable it in the provider’s account or pick another one.
To see how much your agents spend, go to Usage: see Home and usage.
