Changelog

Claude Fable 5 is now selectable in Playcode's AI model picker.

Fable 5 is Anthropic's highest-capability generally available Claude model for demanding reasoning, coding, and long-horizon agent work. It has much higher credit use than Sonnet and Opus models, so the picker shows it as a premium option for the hardest tasks.

Claude Sonnet 5 credit estimates now account for its launch pricing and newer tokenizer together.

The model picker badge and actual credit use are aligned, so Sonnet 5 should no longer overstate expected credits during the introductory pricing window.

Pro mode now starts new chats at Extra High effort when you have not chosen a different default.

This gives the default Quality model more room to reason through multi-step build and debugging work. You can still choose Low, Medium, High, Extra High, or Max from the Intelligence setting when you want to trade speed and credit use for depth.

Claude Sonnet 5 is now the default Quality model in Playcode.

New Pro chats use Sonnet 5 for the Quality path by default. Existing users who were following the previous default move with the Quality setting automatically, so they do not need to change anything in Preferences.

Opus 4.6 remains available in the model picker for work where you explicitly want Opus.

Claude Sonnet 5 is now selectable in Playcode's AI model picker.

It is a new Sonnet option for builders who want a stronger balanced model without jumping all the way to Opus. Sonnet 5 uses Anthropic's newer tokenizer, and the model picker badge accounts for expected credit use.

Opus 4.6 remains the default Quality model for now while we watch Sonnet 5 on real website-building work.

Pro Quality mode now runs directly on Claude Opus 4.6 with extended thinking turned on. It's noticeably more stable and consistent on longer, multi-step work, and the model is shown by name in the AI Model picker and your usage history.

Nothing to change on your side - Quality just gets the upgrade. The Intelligence dial still tunes how hard it thinks per task, and Economy mode stays the fast, lightweight lane.

When you ask the AI to recreate a design from a screenshot, check how a page looks, or work with an image, it now sees the actual picture - not just a link to it.

Before, the AI could take a screenshot but sometimes couldn't really look at it, so it would capture the same page over and over without making progress. That's fixed. Now it looks once and gets to work.

What the AI can see now:

• Screenshots it takes of a live page - so it can clone a design you point it at, or check that your published site looks right.
• Images it generates or edits - it sees its own result, so it can judge it and refine instead of working blind.
• Any image you give it a link to - paste an image URL and ask the AI to describe it, match its style, or build from it.

It also accepts more image formats automatically (including AVIF) and resizes large images for you, so you don't have to convert anything first.

Pro mode now lets you choose how much the AI thinks before it answers. Open the mode picker in the chat and set an Intelligence level for the task in front of you:

• Low / Medium - quick answers for simple edits, with less waiting
• High (the default) - the balanced setting that fits most work
• Extra High / Max - let the model reason longer on hard, multi-step problems

Set it per chat from the mode picker, or choose a default for every new chat in Preferences > AI Model > Default Intelligence. Economy mode stays the fast, simple lane, so there's no dial to think about there.

Also in this release

• No more blank Pro replies - on rare occasions a Pro answer could come back empty; those now retry automatically instead of showing nothing.

Picking Premium mode in the AI chat sometimes did nothing in a freshly opened project - the switch quietly snapped back to Economy. That's fixed: your mode choice now sticks in every project, even before you've sent your first message.

Improvements

• Premium mode is selectable everywhere - the choice is saved the moment you make it, in any project
• Set your default mode - choose whether new chats start in Economy or Premium from Preferences > AI Model > Default Mode, and it applies across all your projects

Pointing your own domain at an app is the step where most people get stuck. So we rebuilt it into a guided setup wizard for Playcode Cloud apps that walks you through it, step by step.

Open Custom domains in the publish menu, type the domain you own, and the wizard does the hard part:

• One record, not a pile of them. It detects your DNS provider, shows the single record to copy, and the exact name your provider expects. No TXT ownership record, no IP addresses, no certificate to install.
• Ownership and SSL are automatic. Once your record resolves, Playcode confirms the domain is yours and issues the HTTPS certificate for you.
• Close the window and walk away. Setup can take a few minutes for DNS to update, so we email you the moment your domain is live instead of making you wait and refresh.
• Root or www, handled. Want yourdomain.com without the www? The wizard shows the right record when your provider supports it, and points you to www when it doesn't.

Each step has a plain-language Need help? panel answering the questions first-timers actually ask, so you never need to know what a CNAME is to finish.

See the full walkthrough in the custom domain help guide.
