OpenAI Yanked a ChatGPT Update. Here’s What It Said and Why It Matters

The company says it plans to be more careful when releasing updates in the future.

Recent updates to ChatGPT made the chatbot far too agreeable and OpenAI said Friday it’s taking steps to prevent the issue from happening again.

In a blog post, the company detailed its testing and evaluation process for new models and outlined how the problem with the April 25 update to its GPT-4o model came to be. Essentially, a bunch of changes that individually seemed helpful combined to create a tool that was far too sycophantic and potentially harmful.

How much of a suck-up was it? In some testing earlier this week, we asked about a tendency to be overly sentimental, and ChatGPT laid on the flattery: «Hey, listen up — being sentimental isn’t a weakness; it’s one of your superpowers.» And it was just getting started being fulsome.

«This launch taught us a number of lessons. Even with what we thought were all the right ingredients in place (A/B tests, offline evals, expert reviews), we still missed this important issue,» the company said.

OpenAI rolled back the update this week. To avoid causing new issues, it took about 24 hours to revert the model for everybody.

The concern around sycophancy isn’t just about the enjoyment level of the user experience. It posed a health and safety threat to users that OpenAI’s existing safety checks missed. Any AI model can give questionable advice about topics like mental health but one that is overly flattering can be dangerously deferential or convincing — like whether that investment is a sure thing or how thin you should seek to be.

«One of the biggest lessons is fully recognizing how people have started to use ChatGPT for deeply personal advice — something we didn’t see as much even a year ago,» OpenAI said. «At the time, this wasn’t a primary focus but as AI and society have co-evolved, it’s become clear that we need to treat this use case with great care.»

Sycophantic large language models can reinforce biases and harden beliefs, whether they’re about yourself or others, said Maarten Sap, assistant professor of computer science at Carnegie Mellon University. «[The LLM] can end up emboldening their opinions if these opinions are harmful or if they want to take actions that are harmful to themselves or others.»

(Disclosure: Ziff Davis, CNET’s parent company, in April filed a lawsuit against OpenAI, alleging it infringed on Ziff Davis copyrights in training and operating its AI systems.)

How OpenAI tests models and what’s changing

The company offered some insight into how it tests its models and updates. This was the fifth major update to GPT-4o focused on personality and helpfulness. The changes involved new post-training work or fine-tuning on the existing models, including the rating and evaluation of various responses to prompts to make it more likely to produce those responses that rated more highly.

Prospective model updates are evaluated on their usefulness across a variety of situations, like coding and math, along with specific tests by experts to experience how it behaves in practice. The company also runs safety evaluations to see how it responds to safety, health and other potentially dangerous queries. Finally, OpenAI runs A/B tests with a small number of users to see how it performs in the real world.

The April 25 update performed well in these tests, but some expert testers indicated the personality seemed a bit off. The tests didn’t specifically look at sycophancy, and OpenAI decided to move forward despite the issues raised by testers. Take note, readers: AI companies are in a tail-on-fire hurry, which doesn’t always square well with well thought-out product development.

«Looking back, the qualitative assessments were hinting at something important and we should’ve paid closer attention,» the company said.

Among its takeaways, OpenAI said it needs to treat model behavior issues the same as it would other safety issues — and halt a launch if there are concerns. For some model releases, the company said it would have an opt-in «alpha» phase to get more feedback from users before a broader launch.

Sap said evaluating an LLM based on whether a user likes the response isn’t necessarily going to get you the most honest chatbot. In a recent study, Sap and others found a conflict between the usefulness and truthfulness of a chatbot. He compared it to situations where the truth is not necessarily what people want — think about a car salesperson trying to sell a vehicle.

«The issue here is that they were trusting the users’ thumbs-up/thumbs-down response to the model’s outputs and that has some limitations because people are likely to upvote something that is more sycophantic than others,» he said.

Sap said OpenAI is right to be more critical of quantitative feedback, such as user up/down responses, as they can reinforce biases.

The issue also highlighted the speed at which companies push updates and changes out to existing users, Sap said — an issue that’s not limited to one tech company. «The tech industry has really taken a ‘release it and every user is a beta tester’ approach to things,» he said. Having a process with more testing before updates are pushed to every user can bring these issues to light before they become widespread.

Kohler Wants to Put a Tiny Camera in Your Toilet and Analyze the Contents

The company’s new Dekoda toilet accessory is like a little bathroom detective.

Some smart litter boxes can monitor our pets’ habits and health, so having a camera in our human toilet bowls seems inevitable. That’s just what kitchen and bathroom fixture company Kohler has done for its new health and wellness brand, Kohler Health.

The $599 Dekoda clamps over the rim like a toilet bowl cleaner, pointing an optical sensor at your excretions and secretions. It then analyzes the images to detect any blood and reviews your gut health and hydration status. Depending on the plan you choose, the subscription fee is between $70 and $156 per year.

At toilet time, you sign in via a fingerprint sensor so that the device knows who’s using the facilities. (Please wash your hands before signing out or tracking your progress.) Then, check in with the app for the day’s analysis and trends over time.

Wait until you’re off the pot, though, before you start doomscrolling your health. The device has a removable, rechargeable battery and uses a USB connection.

Kohler says it secures your data via the aforementioned fingerprint scanner and end-to-end encryption, and notes that the camera uses «discreet optics,» looking only at the results, not your body parts.

«Dekoda’s sensors see down into your toilet and nowhere else,» the company says.

Kohler warns that the technology doesn’t work very well with dark toilet colors, which makes sense. I’m sure there could be an upsell model with a light on it. Maybe the company could add an olfactory sensor, since smell reveals a lot about your gut health too. It could track «session» length or buildup under the rim to alert whoever has responsibility to clean it.

Kohler must have been straining to find appropriate lifestyle photos to include with the publicity materials. Many of the images are hilarious, featuring fit-looking men and women drinking water and staring off into space contemplatively — probably thinking about gas.

Does Charging Your Phone Overnight Damage the Battery? We Asked the Experts

Modern smartphones are protected against overcharging, but heat and use habits can still degrade your battery over time.

Plugging your phone in before you head to bed might seem like second nature. That way by the time your alarms go off in the morning, your phone has a full charge and is ready to help you conquer your day. However, over time, your battery will start to degrade. So is keeping your phone plugged in overnight doing damage to the battery?

The short answer is no. Keeping your phone plugged in all the time won’t ruin your battery. Modern smartphones are built with smart charging systems that cut off or taper power once they’re full, preventing the kind of «overcharging damage» that was common in older devices. So if you’re leaving your iPhone or Android on the charger overnight, you can relax.

That said, «won’t ruin your battery» doesn’t mean it has no effect. Batteries naturally degrade with age and use, and how you charge plays a role in how fast that happens. Keeping a phone perpetually at 100% can add extra stress on the battery, especially when paired with heat, which is the real enemy of longevity.

Understanding when this matters (and when it doesn’t) can help you make small changes to extend your phone’s lifespan.

The science behind battery wear

Battery health isn’t just about how many times you charge your phone. It’s about how it manages voltage, temperature and maintenance. Lithium-ion batteries age fastest when they’re exposed to extreme levels: 0% and 100%.

Keeping them near full charge for long stretches puts additional voltage stress on the cathode and electrolyte. That’s why many devices use «trickle charging» or temporarily pause at 100%, topping up only when needed.

Still, the biggest threat isn’t overcharging — it’s heat. When your phone is plugged in and running demanding apps, it produces heat that accelerates chemical wear inside the battery. If you’re gaming, streaming or charging on a hot day, that extra warmth does far more harm than leaving the cable plugged in overnight.

Apple’s take

Apple’s battery guide describes lithium-ion batteries as «consumable components» that naturally lose capacity over time. To slow that decline, iPhones use Optimized Battery Charging, which learns your daily routine and pauses charging at about 80% until just before you typically unplug, reducing time spent at high voltage.

Apple also advises keeping devices between 0 to 35 degrees Celsius (32 to 95 degrees Fahrenheit) and removing certain cases while charging to improve heat dissipation. You can read more on Apple’s official battery support page.

What Samsung (and other Android makers) do

Samsung offers a similar feature called Battery Protect, found in One UI’s battery and device care settings. When enabled, it caps charging at 85%, which helps reduce stress during long charging sessions.

Other Android makers like Google, OnePlus and Xiaomi include comparable options — often called Adaptive Charging, Optimized Charging or Battery Care — that dynamically slow power delivery or limit charge based on your habits. These systems make it safe to leave your phone plugged in for extended periods without fear of overcharging.

When constant charging can hurt

Even with these safeguards, some conditions can accelerate battery wear. As mentioned before, the most common culprit is high temperature. Even for a short period of time, leaving your phone charging in direct sunlight, in a car or under a pillow can push temperatures into unsafe zones.

Heavy use while charging, like gaming or 4K video editing, can also cause temperature spikes that degrade the battery faster. And cheap, uncertified cables or adapters may deliver unstable current that stresses cells. If your battery is already several years old, it’s naturally more sensitive to this kind of strain.

How to charge smarter

You don’t need to overhaul your habits but a few tweaks can help your battery age gracefully.

Start by turning on your phone’s built-in optimization tools: Optimized Battery Charging on iPhones, Battery Protect on Samsung devices and Adaptive Charging on Google Pixels. These systems learn your routine and adjust charging speed so your phone isn’t sitting at 100% all night.

Keep your phone cool while charging. According to Apple, phone batteries perform best between 62 and 72 degrees Fahrenheit (16 to 22 degrees Celsius). If your phone feels hot, remove its case or move it to a better-ventilated or shaded spot. Avoid tossing it under a pillow or too close to other electronics, like your laptop, and skip wireless chargers that trap heat overnight.

Use quality chargers and cables from your phone’s manufacturer or trusted brands. Those cheap «fast-charge» kits you find online often deliver inconsistent current, which can cause long-term issues.

Finally, don’t obsess over topping off. It’s perfectly fine to plug in your phone during the day for short bursts. Lithium-ion batteries actually prefer frequent, shallow charges rather than deep, full cycles. You don’t need to keep it between 20% and 80% all the time, but just avoid extremes when possible.

The bottom line

Keeping your phone plugged in overnight or on your desk all day won’t destroy its battery. That’s a leftover myth from a different era of tech. Modern phones are smart enough to protect themselves, and features like Optimized Battery Charging or Battery Protect do most of the heavy lifting for you.

Still, no battery lasts forever. The best way to slow the inevitable is to manage heat, use quality chargers and let your phone’s software do its job. Think of it less as «babying» your battery and more as charging with intention. A few mindful habits today can keep your phone running strong for years.
