What happens when the credits run out: does the agent pause until the next day, or wait until you upgrade?

How many agents, projects or seats does the free plan allow, and can a colleague use what you build?
- 4
Which models and tools can a free agent use? Free plans often limit the model, the connections to other apps, or how many tasks run at once.
