Frequently Asked Questions
Can I use open-source models through A2Agent?
A2Agent provides hosted API access to several model families. Open-source and open-weight are different license terms; check the license of the exact model release before choosing it. API access does not grant redistribution rights.
How do I compare API costs?
Compare input, output and cache rates for the same model and workload. Check your API key group, top-up conditions and actual metered usage before scaling traffic.
Will my existing coding client work?
Start with the integration guide for your client. You need an A2Agent key, the correct endpoint and an accessible model ID. Support for tools, images and other features depends on the client, model and route.
