Here are a few changes to explore at your own pace.

Worth a closer look.

Make a little tool you can share.

A checklist, event guide or reading shortlist is enough for a first project. Describe what it should do, try it and ask for one improvement.

Explore Sites ↗

Talk an idea through.

Ask a question, answer naturally and change direction out loud. Useful when your idea is easier to explain than type.

Explore Voice ↗

Show the page you mean.

Share a clean window as context and ask a small question about it. Check the answer against the real page.

Explore Appshots ↗

Work on a result together.

Keep documents and shared work in one place, then revise the result with other people and ChatGPT.

Explore Pages and Space ↗

Get help when the job comes back.

Give an assistant one recurring responsibility and decide when it should ask you. The workshop practice also works in a single ordinary task.

Explore Dots ↗

More choices for different kinds of work.

DevDay introduced GPT-6.1 Sol, and Ultrafast support followed in October. You can begin with a model available in your app.

Explore Models and speed ↗

Availability varies by plan, country and workspace. Check the linked guide for your account.
