Sandbox Warm Pool & Faster Cold Starts

New

  • Added a sandbox warm pool so new users get a pre-warmed instance, making sandboxes available within 10 seconds

Improvements

  • Adjusted the model list to pin Kimi K3 at the top and retire M3, K2.7, and DeepSeek V4 Flash

  • Improved post-release handling to auto-refresh stale pages to the new version instead of showing an error page

Bug Fixes

  • Fixed occasional send failures for the first message after a sandbox cold start

  • Fixed team members' sandbox resources not syncing (or wrongly adjusting personal sandboxes) after a team plan change

  • Fixed sandbox disk capacity being rolled back on restart after a plan change adjusted it
