Changelog: May 2026 — knowledge base improvements and new model options
Longer knowledge base support, model selection per project, and a handful of inbox quality-of-life improvements.
Here's what shipped in May.
Longer knowledge base support. We've increased the knowledge base character limit from 8k to 32k characters. Customers running large doc sets can now paste in significantly more content without hitting the cap.
Model selection per project. You can now choose which LLM Gateway model to use on a per-project basis from the project settings page. We've pre-populated the dropdown with the models we've tested and recommend, but you can also enter a custom model ID.
Inbox: unread badge. The conversation list now shows an unread badge on conversations with messages your team hasn't seen. Badge counts reset when you open the conversation.
Inbox: archive bulk action. You can now select multiple conversations and archive them in one action. Useful for cleaning up resolved conversations at the end of a shift.
Widget: branded color inheritance. The widget now picks up your brand color for the header and primary button. Set it once in project settings and it applies automatically.
Bug fix: email threading on reply. Fixed an issue where customer email replies were occasionally creating duplicate messages in the conversation. Inbound email parsing is now more robust against non-standard reply formatting.
Next up: Slack webhook notifications, conversation search, and a public API for pulling usage data.
