Do it yourself
#- Choose the build quality for the task: Economy for simple edits, fixes and basic pages, Standard or Ultra for hard work. Ultra "may use credits several times faster than Economy or Standard". See Models and modes.
- Ask for one part at a time and name it: "Add a fade-in to the pricing cards", not "Add animations to the site". A small request reads fewer files, and it is cheap to check and to undo.
- Before a big job, ask what it will cost. The agent names the work and a starting cost in credits; the final cost can be higher.
- Start a new chat for each new task: in the left panel, under the project, choose New Chat. Each step of the agent carries the chat so far, so every message in a long chat costs more. To see where a chat stands, open the project menu (☰ and the project name): the bottom shows Spent in this chat and Context. At 80% the app says: "Long chats reply slower and cost more - start a new chat for the next task."
- Keep Context at High or lower, and choose a lower Effort for simple changes. The app's advice: "use the lowest setting only for very simple changes, and the highest for the toughest tasks." Both dials are in Choose build quality.
- Watch the first steps of a run, and stop it as soon as it goes the wrong way: choose the stop button (Stop generation), then say what you want instead.
- When the same fix fails two or three times, stop asking for it again. Go back to the last good point with Undo and checkpoints, then describe the problem differently or attach a screenshot.
- Check what the work cost in Settings, Usage. Workspace owners and admins see each request there; other members see who pays.
If it doesn't work
#Credits still go fast
#Open Settings, Usage and look for what used them. Besides the agent's work, credits pay for generated images, video and audio, background tasks, and the hours a Cloud app's computers are awake: see Run a Cloud app. See also Credits went faster than expected.
"You're out of credits. Add more to keep building."
#The workspace has no credits left, and the agent stops. On Pro or Max, add credits: see Top-ups and auto-recharge. On the Free plan, the app offers an upgrade.
"I got stuck in a loop and stopped to save your credits."
#The agent repeated itself and stopped. Send the request again in other words. If the chat is on Economy, try Standard: the app warns that on complex tasks Economy "can sometimes repeat or get stuck in a loop".
Limits
#- The agent cannot see your balance or what earlier work cost. Its estimate is a floor, not a total.
- A stopped run keeps the credits it already used. Undo & resend runs your message again and uses credits again.
- On the Free plan, only Economy is available.
- Where your credits went, by day and by request: see Where your credits went.
