One outside source can flip a shopping agent's choice end to end
Wharton School researchers found that one outside source could shift the product recommended by shopping agents by as much as 99 points across models. Meanwhile, GitHub removed the 300-file ceiling from Copilot review, and Plaud put an agent behind an eSIM-enabled earphone case. Delegated AI is widening its reach, while each surface exposes a different control point: input order, developer feedback or recording boundaries.

Source order moves the choice
A Wharton School team tested shopping recommendations in ACES, a simulator that shows product-page images to 6 models. One outside source such as Wirecutter shifted the recommended product's share by as much as 99 points for some models. The choice could also move when the same sources arrived in a different order, while product placement on the page and preferences written into user memory had further effects. A product that looked better on objective measures sometimes lost. The work indicates that asking the same agent the same question does not secure a consistent or optimal purchase; the paper is not presented as peer-reviewed.[1]
Code review reaches larger requests
GitHub removed the 300-file and 20,000-line ceiling from Copilot code review. Pull requests opened by the Copilot cloud agent can now receive a full review instead of a limited one; if an organisation enables the required policy, bot-authored requests that cannot be attributed to a licensed Copilot account can also be reviewed and billed to the organisation. When closing a Copilot comment, a developer can now choose addressed, won't fix or incorrect as the reason. GitHub says it will use this feedback to improve the product, though the announcement does not separately identify the covered plans or availability stage.[2]
The agent moves into an earphone case
Plaud added an eSIM to the case for its Plaud One earphones, now open for preorder at 249 dollars. The company says this lets a user give work to an agent remotely without a phone or computer. The case can capture speech from up to 5 metres away; the system transcribes conversation and prepares work such as a follow-up email through connections to Gmail, Google Calendar, Notion and Slack. The first 300 minutes of transcription each month are free. Limited shipping is expected in the final quarter of 2026, while the company's material does not separately define recording range or retention for people who are not part of the conversation.[3]
