OpenAI unveils Lockdown Mode to protect sensitive data from prompt injection attacks
OpenAI announced a new feature that it says will provide additional protection from prompt injection attacks, where malicious chatbot instructions are hidden in webpages and other content sources.
Among other things, Lockdown Mode will disable live web browsing (so you can only access cached content), the retrieval and display of images from the web (you can still generate images), deep research, and agent mode.
The company says that even with Lockdown Mode turned on, ChatGPT could still be vulnerable to prompt injections — which could, for example, “appear in cached web content or in an uploaded file, and could still affect the behavior or accuracy of a response.”
But the goal is to reduce the likelihood that sensitive data gets shared in the process.
“Lockdown Mode is not intended for everyone,” OpenAI says. “It is designed for people and organizations that handle sensitive data and want stricter protection from data exfiltration risks related to prompt injection.”
The company says it’s currently rolling Lockdown Mode out to self-serve ChatGPT Business accounts, as well as eligible personal accounts.

Uber, Wayve and Waymo are headed towards a robotaxi showdown in London
Uber customers in the U.K. can now join an interest list to increase their chances of being matched with a Wayve autonomous vehicle — another sign that the two companies are preparing to launch a robotaxi service in London. When that launch does happen, Uber will be competing directly with Waymo, Alphabet’s self-driving company that is considered the robotaxi leader in the United States.
Uber announced the interest list on Monday in London along with a branded, black Ford Mustang Mach-E equipped with Wayve’s self-driving system. While Wayve is handling the autonomous vehicle tech, Uber has designed what happens inside, including how riders will interact with the vehicle through interactive touchscreens that support 64 languages.
Uber has teased the impending robotaxi service, but has yet to provide an official date, only saying it will launch in the coming months, pending regulatory approval. After launch, Uber customers who request a ride on the app may be matched with a Wayve vehicle, at no additional cost compared with a traditional human-driven one.
Riders can increase their chances of getting a robotaxi by going into their account settings, clicking on rider preferences, and selecting autonomous vehicles. If matched with an AV, riders will be able to decline it and opt for a human driver. The Wayve robotaxis will initially have a human safety operator behind the wheel before fully driverless operations begin in the future, Uber said.

Meanwhile, Waymo is also on London’s streets. In April, Waymo began testing its autonomous vehicles with human safety operators. The company is testing about 100 of its autonomous Jaguar I-Pace vehicles in a 100-square-mile area of the city.
The imminent showdown is complicated by Uber and Waymo’s existing partnership in the United States — one that is already showing signs of wear. The two companies, once rivals in a trade secrets lawsuit, agreed to work together in 2023 when Waymo put its self-driving vehicles on Uber’s app in Phoenix. That partnership has been relatively limited, though, since Waymo lets Phoenix customers directly hail a robotaxi through its own app as well.
The pair expanded the partnership in March 2025, when Waymo agreed to put its vehicles on the Uber app in Austin, and later, in Atlanta. In both of those cities, prospective customers cannot hail a robotaxi directly through Waymo’s app, and have to use the Uber app and hope for a match.
The two companies’ relationship has continued even as they appear to be drifting apart in other areas. Uber has spent the past two years investing in, and partnering with, dozens of autonomous vehicle companies, including Wayve.
Uber executives have also taken direct shots at Waymo, an unorthodox way to treat a business partner. For instance, Uber CTO Praveen Neppalli posted a video and commentary on X calling out the unsafe behavior of a Waymo robotaxi, calling it “scary.”
The ride-hailing giant has launched two new business divisions — a data play called AV Labs, and an operations-focused unit called Uber Autonomous Solutions — that illustrate the company’s broader ambitions to gain market share in the nascent autonomous vehicle industry.
Uber has placed many bets on autonomous vehicle companies that could compete with Waymo, most notably Wayve. In February, the U.K. startup raised $1.2 billion from a number of strategic backers, including Uber as a return investor. The total raise could reach $1.5 billion thanks to another $300 million from Uber contingent on deploying robotaxis, beginning in London.
There is one regulatory hitch that will delay the robotaxi face-off, at least for a while. The U.K. government is in the process of creating autonomous vehicle regulations, and it doesn’t appear to be wrapping up anytime soon. The government’s transportation department opened applications in May for companies interested in its AV pilot program. The department said it will take what it learns from the pilot program and apply it towards the development of its regulations.

Notion restores access to Anthropic after service disruption
Notion’s integration with Anthropic apparently had a hiccup this weekend.
Early Sunday morning, the company posted, “Anthropic’s Opus 4.7 and 4.8 models are experiencing degraded performance, which is causing a higher rate of failures for users selecting these models in Notion AI.”
As a result, Notion said it was disabling use of “all Anthropic models” in its automated productivity tool.
Twelve hours later, Notion’s head of product Max Schoening wrote that he was “astonished” at “the amount of people RT-ing this because they want a story around model quality to be the reason.” (According to the public stats on X, Notion’s post has been reposted around 1,200 times.)
“The degraded performance was a temporary service disruption,” Schoening said. “This happens. It happens to Notion, GitHub, AWS, your OpenClaw, and everything in between.”
He added that Notion has restored access to Anthropic’s models.
Meanwhile, an Anthropic spokesperson said in a statement, “A brief infrastructure issue caused elevated errors on multiple Claude models for a short period of time. The issue has since been resolved. We’re grateful to our users for their patience while we worked to restore service.”
