How credits work
1 credit = $1 of AI compute at cost. Credits cover the tokens your coding agents consume while working on tasks.
- Free tier: hard cap at your included credits. Once you hit the limit, tasks cannot be created until the next billing period.
- Pro and Max tiers: you can optionally set an overage limit in Settings > Billing. If no limit is set, there is no hard cap and you are billed for usage beyond your included credits.
- BYOK (Max tier): when you bring your own API keys, you pay the AI provider directly. BYOK usage is tracked in Twill for visibility but is not billed through Twill.
What counts as usage
Credits are consumed by the AI tokens used during task execution — planning, implementation, verification, and CI auto-fix steps. Sandbox compute (the container your code runs in) is included and does not consume credits separately.
Billing period
Credits reset monthly on the anniversary of your subscription start date. Unused credits do not roll over.
Overages
On Pro and Max tiers, you can configure an overage limit from Settings > Billing. This sets a maximum dollar amount of additional spend beyond your included credits. If you prefer no cap, leave the overage limit unset.
Open source
Open-source projects can use Twill for free. Contact the team via the website or Slack to apply.
