August 2025 release notes.

The August 2025 PolyAI Agent Studio release focuses on performance improvements, voice configuration flexibility, and more powerful call review tools, as well as introducing OpenAI’s new model GPT-5 as an option for agents.

Expand the items for details:

Home page updates

The Agent Studio homepage now loads faster and presents key metrics more cleanly. The displayed metrics can be customized to meet the needs of a particular project, so what you see will be unique to your deployment.

What’s new:

• Reduced page load time
• Improved widget layout for better readability
• More consistent alignment across metric cards and charts

AI call summaries

Agent Studio now displays an AI-generated summary at the top of the Conversation Review screen.

What’s new:

• New AI Summary module in the Conversation Review screen
• Generated post‑call using GPT summarization logic

This will only appear by default for projects that have signed the current DPA and support Azure AI..

Multi-voice limit increase

Projects can now have up to 10 active voices, updated from the previous limit of 5 voices.

Voice limits apply per project and can be managed from the settings page.

New call review filters

It is now much easier to filter calls in Conversation Review by delivery status, channel, and other metadata.

What’s new:

• Faster filter response time
• Filter combinations can be applied without resetting the view

Use saved filters to make these configurations instantly reusable.

Updated channel display

Conversation Review now displays additional call attributes and improved channel labels for quicker scanning.

What’s new:

• Clearer channel tags for Inbound, Outbound, and Agent Chat
• Additional metadata columns available for custom table views
• Streamlined column naming for consistency across the platform

GPT‑5 models in Agent Studio (experimental)

We’ve added GPT‑5 options to Agent Studio for evaluation and feedback.

What’s available:

• GPT‑5 nano and GPT‑5 mini: Recommended for most Agent Studio use cases (best balance of quality/latency)
• GPT‑5 (large): Included for testing; note it’s currently slow at 3–4 seconds or more.
• GPT‑5 chat (router): Routes dynamically across the above models so you can experiment quickly.

Switch models from function settings or your project’s model configuration panel.

In-app calling with variants

You can now test calls using a selected variant directly in the Test panel.

What’s new:

• Variant dropdown + search in Test ▸ Call
• Calls launched with the chosen variant’s config
• Transcripts tagged with variant_id for review and filtering

Use this to test prompts, policies, or routing logic before upgrading your deployment to production.

Smart Analyst improvements

It’s now easier to jump from answers to exact conversations. New and more complex SQL data enquires have also been added to the Analyst.

What’s new:

• Clickable Call IDs: Any Call ID in a Smart Analyst answer opens that call’s Conversation Review in a new tab.
• Expanded SQL range: Queries can include additional tables, such as PolyScore and Custom Metrics.

Start/End function error warnings

If a Start or End function has an error that prevents execution, Agent Studio now shows a warning and guidance to fix it.

Agent Analysis – Multi-task

Agent Analysis now supports multiple analysis tasks per project.

What’s new:

• Configure up to 10 analysis tasks per project. Each task can have its own prompt, categories, and color-coding.
• A redesigned chart creation flow with filters, random call selection, and manual call selection.
• A dedicated Batch UI Page where you can see task results, call breakdowns, filters, and categories in one view.
• The ability to click into a call to open Conversation Review, with categorizations still editable at the call level

Use multiple tasks to mimic QA workflows, track quality across different call types, and monitor continuous improvement.
