Integration of Arm Scalable Matrix Extension 2 (SME2) and the Google AI Edge software stack enables high-performance, on-device generative AI by turning the CPU into a powerful matrix-compute accelerator. Using Stability AI’s "stable-audio-open-small" model as a case study, it outlines a streamlined "Convert, Optimize, and Deploy" pipeline that utilizes LiteRT, XNNPACK, and KleidiAI to automate hardware acceleration. The resulting implementation achieves over a 2x speedup in audio generation and a 4x reduction in memory usage while maintaining high audio quality on Arm-powered mobile devices and laptops.

Form creators now have more options for header images in Google Forms. Previously, creators could only use a pre-selected theme, upload an image, or choose an image from Google Photos. In addition to these options, they can now choose an image from Google Drive or Google Images or use a URL. This makes it easier to add an appropriate and compelling header image to your form.

Administrators can now apply a global context-aware access (CAA) policy to all SAML applications within their organization. This update introduces a default assignment that serves as a universal security baseline, automatically protecting any SAML-based app that does not have a specific policy already assigned. By establishing this "secure-by-default" posture, IT teams can help protect internal data and third-party SaaS tools as new applications are integrated into their ecosystem.

We are excited to announce a significant expansion of the Google Ads A/B experiments feature set in the v24.1 release, launched yesterday, May 13, 2026. We know API functionality is critical for advertisers who manage large sophisticated accounts, and we want to give these advertisers the capability to better create and manage their A/B experiments at scale. This update broadens the platform's current scope, enabling advertisers to leverage the power of experiments for a broader range of testing scenarios to drive campaign performance.

Direct experiment reporting

One of the most requested enhancements is the ability to query experiment statistics directly through the API. Previously, you had to manually calculate statistics by querying campaign resources. With v24.1, we are exposing experiment arm-level and significance stats, including:

• Control arm stats: The average value of metrics in the control arm.
• Point estimates: The mean value of the difference between the control and treatment arms, calculated via the jackknife method.
• Margin of error: The radius of the confidence interval.
• P-values: Represents the calculated probability that the difference could have occurred by chance.

New experiment types

We are expanding support for a variety of experiment types to help you find the best configurations for your business:

• Feature-specific tests (AI Max and broad match): Test the impact of enabling AI Max or broad match keywords. These use an intra-campaign workflow, where the feature is tested within the original campaign shared by both the control and treatment arms.
• Custom video experiments: Run custom experiments consisting of Video campaigns.
• Performance Max replacement: Test how your Shopping campaigns perform compared to Performance Max.
• Performance Max asset optimization: Specifically for Performance Max, you can test different variations of assets including text, images, and videos. This asset optimization workflow helps determine which creative combinations drive the best results.

While these updates cover a significant number of use cases, we are continuing to work on the platform and plan to introduce even more experiment types in future releases.

Where can I learn more?

Updated documentation and code examples are available on the Google Ads API Developer site. We also encourage you to join the discussion and share your feedback on our Ads and Measurement Community Discord server.
