To toggle this, you’ll need to have the “assistant” type selected in the experiment’s edit screen, then go to the “Advanced” tab. There you will see a “Citations enabled” setting. When this setting is “off”, no citations will be present in the response.

Oct 29, 2024:

  • CHANGE [Security update] Participants will now have to verify their email address before they can continue to the chat session.

  • NEW Terminal bot. You can now configure a bot (from an experiment’s homepage) to run at the end of every inference call.

A terminal bot is useful when you want to ensure that the bot always responds in a certain language.
  • CHANGE The {source_material} and {participant_data} prompt variables can now only be used once in a prompt. Including this variable more than once in the same prompt will not be allowed.

July 19, 2024:

  • NEW In-conversation file uploads for assistant bots on web based chats. These files will be scoped only to the current chat/OpenAI thread, so other sessions with the same bot will not be able to query these files.

July 15, 2024:

    • Look for "Pipelines" in the sidebar
    • Ability to run a pipeline based on event triggers
    • Ability to create a pipeline visually
  • NEW Participant view
    • View participants with their data
    • We added a view where users can see all participants, when they joined initially and what experiments they participated in.
    • Experiment admins will also be able to add or update data to be associated with a participant. When the experiment prompt includes the {participant_data} variable, this data will be visible to the bot and participant specific details can be referenced or considered during the conversation.
    • Note that participant data is scoped to the specific experiment. This means that you have to manually add data pertaining to a particular participant to each experiment manually.
  • NEW Slack integration
    • Ability to connect to a slack workspace as a messaging provider
    • Ability to link an experiment to a Slack Channel (via an experiment channel)
    • Ability to have one 'fallback' experiment which can respond to messages on channels where no other experiment is assigned
    • Experiment responds to 'mentions' and creates a new session as a Slack thread

Jun 4, 2024

  • CHANGE Individual tool selection
    • Users can now choose which tools to give to the bot to use.
    • Previously this was obscured by a single “tools enabled” checkbox which - when enabled - gave the bot all the tools that existed at that time.
    • Tools include: One-off Reminder, Recurring Reminder and Schedule Update
    • One-off Reminder: This allows the bot to create a one-time reminder message for some time in the future.
    • Recurring Reminder: This allows the bot to create recurring reminder messages.
    • Schedule Update: This allows the bot to update existing scheduled messages. Please note that this tool cannot update reminders created with the one-off and recurring reminder tools, since those are legacy tools using a different framework. Future work will fix this.
  • CHANGE When and error occurs during the processing of a user message, the bot will tell the user that something went wrong instead of keeping quiet

May 21, 2024

  • NEW OpenAI Assistants v2 support
  • NEW Multi-experiment bots
    • Allows users to combine multiple bots into a single bot, called the “parent” bot. The parent bot will decide which of the “child” bots the user query should be routed to, based on the prompt.
    • The prompt should give clear instruction to the parent bot on how it should decide to route the user query.

May 15, 2024

  • CHANGE Experiment search improvements
    • The search string will be used to search for experiments by name first, then by description
  • NEW OpenChatStudio API: A few endpoints are exposed to allow chatting to a bot using the API

    • If participant data exists and was included in the prompt, then reviewers will be able to see the data in the session review page. Seeing the data that the bot had access to might help with understanding the conversation.
  • CHANGE Anthropic now also supports tool usage!

Apr 30, 2024

  • NEW Participant data
    • Participant data allows the bot to tailor responses by considering details about the participant.
    • To include participant data in the prompt, go to the experiment edit page and add the {participant_data} variable to an appropriate place in the prompt.
    • Currently we have to create it manually through the admin dashboard, but a near future release will include a dedicated page to view/edit participant data.
    • Please note that participant data is experiment specific, meaning that data we have for a participant in one experiment may not be the same for the next experiment.
