For years, BMW’s sport sedans have been the benchmark if you wanted a car that could comfortably handle both your daily commute and a back-road blast without breaking a sweat. The M3 and M340i, in particular, built their reputations on delivering serious performance without completely sacrificing refinement.

Our recent paper, “LLMs Corrupt Your Documents When You Delegate”, has generated discussion about the reliability of AI systems in delegated workflows. We appreciate the interest in this work and want to clarify several important points about what the paper does—and does not—claim.

The research aims to develop robust evaluation methods for long-horizon delegated and collaborative tasks. More broadly, this work reflects an ongoing effort to better understand the gap between strong benchmark performance and certain real-world tasks. Using a controlled evaluation methodology, we examine how well information is preserved across these extended workflows. Within this constrained setting, we observe that models can accumulate fidelity degradation over repeated edits. Note however, that current production systems can mitigate these effects through verification loops, orchestration, and domain-specific tooling.

Our goal is not to argue against the use of AI systems in professional workflows, but rather to identify where current systems need further research and engineering to help make them more trustworthy collaborators. This benchmark is intended as a diagnostic tool for examining delegation patterns, not a measure of overall model capability, task success, or user outcomes.

Main results

The paper evaluates a specific interaction pattern we call delegated work—situations where a user entrusts an AI system to carry out multi-step modifications to important artifacts such as documents, spreadsheets, code, or structured files with limited human verification between steps.

We use chained transformation-and-inversion tasks that evaluate whether semantic content is preserved accurately across extended delegated workflows. Our evaluation uses domain-specific semantic parsing to focus on meaningful changes to the underlying artifact rather than superficial formatting or stylistic differences. The errors we report thus correspond to degradation in the underlying semantic content but, our measure of “corruption” did not include task completion or user satisfaction.

Using this methodology, we find that current frontier models can introduce sparse but consequential errors during long-horizon workflows, and that these errors may accumulate over repeated interactions. Across the evaluated settings, strong state-of-the-art models showed roughly a 19–34% degradation in artifact fidelity over 20 delegated iterations. Notably, Python workflows generally exhibited stronger robustness under extended delegated interactions, with less than 1% degradation on average.

DELEGATE-52 was intentionally designed as a stress test for long-horizon delegated execution. The benchmark evaluates whether systems preserve artifact integrity across extended sequences of transformations and inversions.

The study focuses specifically on delegated execution with limited human intervention between steps. It does not attempt to measure the full range of real-world AI deployments, many of which involve substantially more oversight, verification, and workflow structure.

The paper also evaluated a simplified agentic harness with tool use capabilities such as Python execution and file operations. While this setup did not eliminate the observed degradation, it should not be interpreted as representative of production-grade systems optimized for specific workflows or enterprise domains.

Implications

We believe the primary implication of this work is that reliable long-horizon delegation remains an important open research and engineering challenge.

The results suggest that strong short-horizon benchmark performance alone may not guarantee dependable delegated execution over extended workflows. At the same time, the findings should not be interpreted as evidence that AI systems lack practical value in real-world work today.

In practice, many deployed AI systems combine models with specialized harnesses, orchestration layers, retrieval systems, verification procedures, memory mechanisms, and human oversight designed to improve reliability and deliver useful user outcomes despite underlying model limitations. We expect continued improvements in models, workflow-aware training, memory systems, and production-grade agentic harnesses to further reduce these failure modes over time.

In a world that often thrives on being far too serious, outrageously funny TV shows deliver much-needed relief because they’re proudly unapologetic and completely unforgettable. They don’t just aim for a giggle — they go all-in with laugh-out-loud chaos, socially unacceptable characters, razor-sharp writing, and wildly entertaining moments.

Certain Xfinity customers can now claim their portion of a $117.5 million class action lawsuit settled by communications giant Comcast.

Between Oct. 16 and Oct. 19, 2023, a third party accessed personally identifiable information for more than 35.8 million Xfinity customers, exposing usernames, passwords, contact information, and, in some instances, partial social security numbers. Multiple lawsuits against the company were consolidated into a class action case in 2024, alleging Comcast "failed to properly protect personal information" and had "inadequate data security" that led to the criminal cyberattack.

Settlement email: Is it real?

Comcast notified Xfinity customers impacted by the breach via email on December 18, 2023. Anyone who received an email notification at that time is eligible to file a claim (which means not all Xfinity customers can claim the cash).

Affected customers may have received additional notification emails from Kroll Settlement Administration LLC, the court-approved claims administrator. These emails, referencing both reference KSA and the Hasson v. Comcast Cable Communications case, will include individual class member IDs necessary to submit claims on the official settlement page.

If you've received notice via email or mail, but are unsure if its legitimate, call the settlement customer service line at (833) 319-2401 to confirm your eligibility.

How to claim your money

Settlement members have until September 14 to submit a claim online or via mail.

Individuals can receive a $50 fixed payout or request reimbursement for any "documented out-of-pocket losses and lost time, the cost of Identity Defense Services and Restoration Services, and court-approved attorneys’ fees and expenses" up to $10,000, according to the settlement website.

Members have until July 1 to exclude themselves or object to the settlement.

Is Apple's partnership with OpenAI about to fall apart?

According to both Bloomberg's Apple insider Mark Gurman and a new report in the New York Times, AI giant OpenAI is currently considering suing Apple over the companies' agreement to integrate ChatGPT into some Apple Intelligence AI features.

Apple recently reached a $250 million settlement in a class action suit over its failure to deliver on its AI promises. (Apple hasn't admitted to any wrongdoing.) Now, OpenAI may serve Apple with a breach of contract notice, the Times reports.

Mashable 101 Fan Fave: Vote for your favorite creator today!

In 2024, OpenAI and Apple surprised the industry by partnering together on Apple's upcoming AI features known as Apple Intelligence. OpenAI's ChatGPT was expected to be prominently featured in Apple products, such as the iPhone and MacBook, powering Apple Intelligence. 

In addition, OpenAI appeared to be a key technology behind Apple's relaunch of its voice assistant Siri as an AI assistant. 

According to the reports, however, OpenAI is unhappy with how the now two-year-old partnership has panned out so far. The fallout appears to stem from how Apple integrated ChatGPT into its products.

OpenAI reportedly expected that the partnership would encourage Apple users to subscribe to ChatGPT. Instead, OpenAI found that ChatGPT is difficult for users to even find within Apple Intelligence. On top of that, in January, Apple confirmed that it had struck a deal with Google to use Gemini to power Apple Intelligence, including Apple's long-awaited AI relaunch of its voice assistant Siri.

SEE ALSO: Apple picks Google Gemini over ChatGPT to power the new AI Siri

All of these issues have led OpenAI to consider taking legal action against Apple, claiming breach of contract.

We'll see if OpenAI actually follows through with a suit against Apple, or if the company is trying to renegotiate its agreement.

The AI company is currently awaiting the jury's decision regarding its own future following a trial stemming from the lawsuit Elon Musk filed against ChatGPT creator Sam Altman.

Google is testing out a change to Gmail that might make the service a little bit less useful for newcomers.

The company confirmed to Android Authority that it is testing a policy shift that would see new Gmail accounts get a mere 5GB of free cloud storage, down from the 15GB that's been guaranteed to Gmail accounts for years. This change wouldn't affect existing accounts that already have 15GB of free storage, but anyone who wants to make a new account would be limited, at least as long as they live in one of the regions where this is being tested.

According to Android Authority, the test is largely limited to African countries right now.

SEE ALSO: Gmail's 'Help me write' will now sound more like you

"We’re testing a new storage policy for new accounts created in select regions that will help us continue to provide a high-quality storage service to our users, while encouraging users to improve their account security and data recovery," Google said in a statement to Android Authority.

The good news is that there is a way around this. Users who want the free 15GB of storage can simply attach a phone number to their account, and the 5GB limit will be lifted. Obviously, there might be security concerns associated with doing such a thing, but a fix is a fix. And, as Google's statement said, attaching a phone number to an account can actually increase its security through two-factor authentication, among other reasons.

Of course, this is only a test, so it may not ever become a global policy. If you don't already have a Gmail account, now might be the time to make one. You can also change your Gmail username, another recent change to long-standing Google policy.

A lot of people took one look at the Spotify app on their phones this week and didn't like what they saw.

Spotify updated the app icon to give it a shiny, disco ball-like appearance. If you aren't prepared for it, it's a pretty jarring shift. See for yourself:

SEE ALSO: Spotify has a new Wrapped-like experience that covers its entire history This Tweet is currently unavailable. It might be loading or has been removed.

If you're here, you're probably wondering why Spotify did that, and if it's going to be that way forever. For starters, no, it's not going to stay that way permanently. That's because Spotify did this to celebrate its 20th anniversary as a company (even though the app launched in 2008). This new icon is just a way to celebrate a huge milestone for the popular music streaming service. As a fun bonus, you can also see a bunch of cool data about your music streaming history in Spotify thanks to a Wrapped-like experience built into the app right now. If you want to know the first song you ever streamed, you can do that. Just prepare to cringe a little bit.

The change makes sense once you know all of that, but still, people online were not entirely happy about the jarring shift in aesthetic from Spotify.

There's nothing to worry about, though. Just let the company celebrate itself for a little while.

Summer is coming, which means booking flights and getting passports ready for travel. The ubiquitous gay hookup app, Grindr, just launched Season 3 of its show Host or Travel and revealed the top gay travel destinations of the year. Any guesses?

Host or Travel explored "gayborhoods" in cities like Los Angeles and Rio de Janeiro in the past. This season, Grindr explores the likes of Sydney, Australia, Austin, Texas, and more, including the number one destination for gay travelers in 2026: Paris, according to new global Grindr data.

SEE ALSO: The great Grindr glossary: all terms and acronyms explained

Grindr analyzed global in-app behavior to find where its users are going, chatting with, and connecting the most, and the French capital shot up to the top, according to a press release shared with Mashable. Rio de Janeiro, New York City, Bangkok, São Paulo, and Berlin are the other most-frequently visited cities among Grindr users.

"Grindr is the digital home for the community, and Host or Travel was created from the understanding that for gay travelers, finding your people in a new city isn't just a nice-to-have, it's crucial," Grindr's CMO, Tristan Pineiro, stated in the press release.

Pineiro said that the app built this series to celebrate how the gay community finds strength in numbers. Grindr users aren't just looking for dates, but they're using the app to curate adventures, find safe spaces, and experience the world through the eyes of locals.

And it's not just the aforementioned cities that are hot spots for gay visitors. Grindr found that use of its "Right Now" feature (aka who is free to meet...right now) is highest in Taiwan, the Philippines, Lima, Buenos Aires, and Medellín. Meanwhile, lots of late-night chats occur in Manila, Taipei, and Buenos Aires, while San Salvador, Colombo, and Kathmandu are most active in the early morning.
