ZeroTwo lists what changed in each release inside the app and on its website. The notes cover new features and fixes, and sometimes changes to which models a plan can use. To see which models you can use today, check the model picker, and to compare what models cost in credits, open Model Tiers.
Read the release notes in the app
- Click the question-mark button labelled Help and what's new in the sidebar footer.
- Under What's new, pick a recent release to open its notes, or choose Full changelog.
The full changelog opens as a side panel. Each entry shows a version number (for example v1.1.32), a title and a date, newest first. The panel lists the release you are running and earlier ones; notes for versions newer than your app are not shown. If the notes cannot be loaded, the panel says "Full release notes are unavailable right now."
ZeroTwo for iOS and ZeroTwo for Android also have a Help and what's new menu with the same What's new list and Full changelog entry.
Read the changelog on the website
The public changelog is at zerotwo.ai/changelog. It is also linked as Changelog in the footer of zerotwo.ai. You do not need to sign in to read it.
See which models you can use
Release notes are written per release, so they are not a full model list. For the current catalog, use the model picker or open the Model Tiers dialog:
- Open Help and what's new and choose Help.
- Choose Model Tiers.
The dialog shows a plan table with monthly credits, the credit cost of tools and generated media, and the models grouped by how many credits they use:
- Free — Lowest Cost: costs about 0 credits and is available on every plan.
- Low Credit Cost: draws very few credits per message.
- Standard Credit Cost: moderate credits per message.
- High Credit Cost: uses more credits because the provider charges more.
- Flagship — Highest Cost: the highest credit cost per message.
Model Tiers is in the web and desktop apps. The iOS and Android Help menus do not have it.
