Billing questions
Know what you’re paying for.
Is there a fixed price per task?
No. Cost depends on which models run and how much work the task involves. A quick question and a multi-step change will cost different amounts.
How do I add funds?
Open Usage & Billing in the extension. Top-ups accept whole-dollar amounts from $5 to $500, and you confirm the amount before checkout.
Where can I review a charge?
Every run shows its usage, and Usage & Billing lists your history. For a charge you don’t recognize, email support@codemux.net with the approximate time. See our refund review process.

Install the extension, open a repository, and start with one concrete task.
