May 2026 release notes.

The May 2026 PolyAI Agent Studio release ships a redesigned Conversations workspace built for high-volume review, adds a one-click Tripleseat integration for restaurant agents, and brings Cartesia’s Sonic 3.5 voice model to Agent Studio.

Expand the items below for details:

Conversations workspace revamp

The Conversations page is now organized around channel scopes, saved views, layered diagnosis, and an integrated review side panel — purpose-built for analyzing conversations at scale.

• Voice and Webchat as separate scopes — each with their own saved views, column layouts, and an integrated review side panel that opens without leaving the table.
• Saved views — built-in Production and Test System Views, plus your own Custom Views as pinned tabs. Duplicate, set as default, and share filters as a link.
• Diagnosis toggle group — debugging layers (tool calls, flows, variables, latency, logs, sources) are now independent toggles that persist as you move between conversations.

See Conversation review, Views, and Diagnosis for the full walkthrough.

Cartesia Sonic 3.5 voice model

Cartesia’s latest TTS model, Sonic 3.5, is now selectable for any Cartesia voice. Pick it from the model dropdown when adding or editing a Cartesia voice, or set model_id="sonic-3.5" in CartesiaVoice.

Sonic 3.5 inherits all Sonic 3 behavior:

• 10-emotion set via the emotion parameter
• volume control (e.g. 0.5–2.0)
• Speed range 0.6–1.5

No code changes are required for existing Cartesia voices — switch the model ID to opt in.

Tripleseat integration

Connect PolyAI to Tripleseat to capture event and large-party leads from voice, webchat, and SMS conversations — without writing custom code. Projects on the PLG restaurant template can connect Tripleseat through one-click OAuth from the Integrations page; other projects continue to be supported through Managed Services.

See Tripleseat for the setup guide.
