A model run, on a model page or with the API, needs a balance of at least $0.50. Training models, which fine-tune a model on your data, need $10, and Wiro Studio needs $10 before you can send a message.
It isn't a fee. Nothing is taken when you start a run; you pay the run's price after it finishes, normally only if it succeeds.
What counts for a model run: your wallet credit plus coupon credit valid for that model. In a team workspace, or with a team project's API key, it's the team wallet's balance.
Below the minimum: the run is refused, and the API returns
Insufficient balance(code 97). Refused requests aren't charged.Below $20 you can run 1 task at a time: the concurrency limit is 10% of your balance, minimum 1.
To top up, open Credit Balance, then Add to Credit Balance. Details: balance errors and concurrency limits.
