Frequently Asked Questions
How does billing work?
AI Duet uses a pre-load balance system. Top up your account, and usage is deducted per token in real time. No monthly fees, no commitments.
Why is it cheaper than the official API?
We leverage bulk pricing from upstream providers and pass the savings to you. Same models, same quality, lower cost.
Which models are used?
Opus 4.6 handles planning and code review. GPT-5.4 handles code generation. The orchestration is automatic — you just make one API call.
Can I monitor my usage?
Yes. The Dashboard shows real-time token usage, cost breakdown per request, and balance history.
