# Credits

Credits are what we use to control the cost of things. 

Currently in the test net, it is almost completely arbitrary. 

**Model Hub** messages cost 1, 2, or 3 credits per message, per model. The increased cost, reflects the actual cost of calling certain APIs. 

**Agent Hub** - As these do multiple steps sometimes, currently it is just a flat 5 credits. In the future, it will either be just included in your monthly payment, or a pay as you use system. 

**Image Hub** - Currently a flat 10 credits, as it takes the most resources right now. But this cost can easily be brought down when needed. Just kept higher for testing. Will adjust to 3-to-5 credits if we find people really want more images now.<br>
