Versions — compare and go back
The Versions tab — the version list, a diff between two versions, restoring an old one, and trying one question against several versions.
Every Publish new version adds an entry to the Versions tab. The one in use is labelled current. Version numbers only go up — going back never erases history.
See what changed
Compare with current on an older version opens What changed between version X and Y: every changed field (instructions, model, tools, knowledge bases, parameters…) with its before / after value.
Go back
Go back to this on an older version republishes that configuration as a new version
(v+1). The old version stays where it is; run history for the versions in between is kept. Needs
agent.publish.
Try one question against several versions
Pick 2–4 versions, enter one question, run. Ragenta performs real runs — one per version, costing credits as usual — and lays the results side by side so you can compare output, credits and duration. Useful before deciding between Go back to this and keeping the new version.
These runs appear in History with trigger comparison.
