New Features

• The gpt-5.1 model is now available for use in the Side Chat.

• The model search feature and a list of recently used models are now available in the Side Chat.

• The Image Viewer now supports zoom controls and background color changes, making it easier to precisely view images in the Workspace.

• A new "Download page" is now available for the upcoming Arkain downloadable application.

Changes

Container management

• Auto-stop has been enabled by default when creating a container.

• The maximum storage capacity of the container has been changed from 200GB to 80GB.

Arkain Snap

• Added a 4,000-character limit to the Snap input box.

• Improved overall Snap performance and updated Quick Prompts to generate higher-quality results.

• Snap was updated to continue running in the background even when the page is closed or refreshed.

• Snap was updated to resume from where it left off after recharging credits and restarting the container, even if it stopped mid-execution due to insufficient credits.

Workspace

• Filename validation rules have been relaxed to allow most characters supported in Ubuntu-based environments. Only a few characters that could cause functional issues are restricted, offering more flexibility in naming files.

• When uploading files or folders, the Arkain Studio Upload pop-up is no longer displayed. Instead, the native file picker opens immediately, reducing unnecessary steps in the upload process.

UI & Platforms

• Template List page filter and sort preferences are now retained when navigating back from a Template Detail page.

• The default sorting order for template lists has been updated from Recent to Most Used.

• Improved the styling and usability of the Container Settings page and applied a dropdown for already invited users in the Share pop-up.

• Theme selector dropdown UI on the Dashboard page was updated to match the mobile interface for consistency.

• The Side Chat responses now include a typing animation to provide a more natural and engaging interaction experience.
