Recent Changes / Developments

this page is the central place to stay up to date on the latest changes and updates across the platform it also serves as a dedicated resource for integrators, highlighting any modifications that may require action on your end — whether technical updates, configuration changes, or process adjustments we do our best to notify integrators in advance via email whenever a relevant change is coming, but we recommend checking this page regularly to avoid missing anything that could affect your integration changelog \[13/04/2026] here's what's new in product release notes we want to make sure you're always aware of what's new after each deployment, you'll be able to see a summary of newly released features directly from the interface head visual organisation we're continuing to grow the avatar catalogue steadily, and with more visuals comes the need for better organisation we're improving how head visuals are structured and browsed in the interface so the expanded catalogue stays manageable and easy to navigate to learn more, https //docs unith ai/creating head visuals voice interruption you can already stop a digital human's response with the stop button we're now adding the ability to interrupt via voice — so you can cut in naturally, mid response, without reaching for a button this will be configurable per individual head id, giving you fine grained control over where and how interruption is enabled to learn more, please https //docs unith ai/unith embed integration guide#voiceinterruptions custom data tags you can now label each digital human deployment with a custom tag that tag travels through the entire system and appears in your usage logs, so you can finally tell apart which website, campaign, or platform is driving which activity this gives integrators a clean, low friction way to segment usage by deployment, campaign, platform, or whatever distinction is relevant to your setup https //docs unith ai/conversation logs retrieval other from a security standpoint, we have improved the login and sign up flows by introducing token expiry — authentication tokens now expire within 10 minutes for login and 30 minutes for sign up digital humans created in legacy mode are no longer accessible via direct url manipulation, closing an unintended access path the custom words tab in interface digital human's edit now includes a short warning to help users prevent some common issues fixed dh edit error where the user would sometimes see the pending changes dialog incorrectly after a save error changelog \[18/03/2026] we've shipped a significant platform update across the unith interface and api here's what's changed streaming is now the default streaming mode is now active by default for all new digital humans, both from the interface and via the api this includes updated default prompts and template adjustments to ensure optimal behaviour out of the box if you were previously enabling streaming manually, no action is needed — it just works new integrations tab we've added a dedicated integrations tab in the https //app unith ai from there you can retrieve and configure tool calling set up mcp integrations switch the underlying llm model this brings advanced configuration into the ui without requiring api level access voice modal improvements the voice selection modal in interface now includes a clearer filtering experience you can also manually enter a private voice id — useful if you're working with custom or provisioned voices outside the standard catalogue (e g private voices) digital human name and alias now separate in interface when creating a digital human, you can now set the head name and the alias independently this gives you more flexibility in how digital humans are labelled internally versus how they appear to end users stop button & response interruption users can now interrupt an active response with a stop button this gives end users more control over interactions without needing to wait for a full response cycle to complete streaming feature parity with streaming now the default, we've restored and expanded several features that were previously only available in non streaming mode high demand pop up inactivity behaviour browser recommendation prompt automatic browser language detection — the digital human will now match the user's browser language automatically, without any manual configuration data pipeline & environment infrastructure we've deployed a fully updated data pipeline with proper environment separation this gives us significantly better tooling for testing, debugging, and safe iteration before changes reach production there was a small change in the endpoints path new base url https //api data unith ai/ path remove /api/ from any existing paths before https //7bdt5ca661 execute api eu west 1 amazonaws com/api/sessions/ after https //api data unith ai/sessions/ three new avatar visuals we've expanded our head visuals
