The default AI model has been upgraded to GPT-4.1, with the following changes and benefits:
Latency is improved.
GPT-4.1 is better at following instructions than GPT-4o.
GPT-4.1 responses will generally be somewhat shorter than GPT-4o responses.
Agents belonging to all users who don’t have access to AI model selector dropdown have been automatically changed to GPT-4.1.

The Agent Initiative widget is now displayed even if there is active conversation with the agent.

Agent’s prompt input field now correctly displays on mobile devices, including tablets.
Fixed the problem where, if numbered references are enabled, the agent was displaying only one citation, even if multiple were used to build the response.
Fixed the issue where, when the user's account reached processing limit, and limit was removed later, SharePoint auto-sync was ignoring previously limited files if they were not in the meanwhile changed on the SharePoint end.
Fixed the issue where external_id was not always correctly displayed on the Ask page.
Fixed the issue where the error message was missing if domain validation service times out when building an agent using sitemap or website.
Fixed the issue where, sometimes when updating the default payment method, the subscription's payment method didn’t use the new default.
