# 8.2025

> 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](https://openai.com/index/introducing-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.

![homepage-optimization](/_fern-files/_img/9fadd03638ecbe0104b6f6e0bf40fc862937367ed3c465915491da323af720cc.webp)

**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.

![ai-call-summary](/_fern-files/_img/8ac327a35fa0b82209f1ac694d526f8747fce4c41c326789754f24fb5289a149.webp)

**What's new:**

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

> **Warning**
>
> AI Call Summaries are available for eligible projects. Contact your PolyAI representative to confirm availability for your project.

#### Multi-voice limit increase

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

![multi-voice-limit](/_fern-files/_img/7d27e29928d1483035c9ba047b50c5966066ad352e25495fceadd8474b9e8b7e.webp)

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.

![enhanced-filters](/_fern-files/_img/bff671a6fbe74de07ec3f5c3cd9ab51c68e470a0eb397a2632810b28fff394d8.webp)

**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.

![channel-metadata](/_fern-files/_img/f2e836212a9ad93d9d0bf52efcd0299d275b9e4673b9c7fbce1cfbafd4cdc22c.webp)

**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.

![gpt5-models](/_fern-files/_img/6c80bc6abc1bbc3e3bc3b868bebf362317dec600ac56198858e473e4e9afa707.webp)

**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.

![calling-variants](/_fern-files/_img/afa53f281a07a1e8613afa64f64d109781338f6a7b8b43350bd9267a94822fc0.webp)

**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](/agent-studio/deployments/overview).

#### Smart Analyst improvements

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

![smart-analyst-updates](/_fern-files/_img/b295b57573750f03556b33aa4326fad4bdb0450e40a003e8df12cd50fb89a59c.webp)

**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.

![function-warnings](/_fern-files/_img/ee8d0d60b21439f126fd2160692fdd6e86a9b141e9cb0d3528575b62c16dbdfa.webp)

#### Agent Analysis – Multi-task

Agent Analysis now supports multiple analysis tasks per project.

![agent-analysis-multitask](/_fern-files/_img/55c4fa14abc888a6095eb199281ac32e3bc54b4b084ef52e5739794c83e61525.webp)

**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

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