Auto Models · Artifact Refresh · Cleaner Replies

Model Selection
- You can now use Auto and concrete model names instead of the old Lite, Pro, and Max tiers across tasks, bots, timers, and the Kollab CLI.
Task & Artifact Reliability
- Fixed manual artifact refresh so agents read the latest saved content before responding.
- Fixed artifact cards so newly updated agent content appears without stale previews.
Assistant Replies
- Fixed internal helper terms leaking into assistant replies, so responses read more naturally.
