Child abuse images removed from AI image-generator training source, researchers say
Washington (AP): Artificial intelligence researchers have said they deleted more than 2,000 web links to suspected child sexual abuse imagery from a dataset used to train popular AI image-generator tools.
The LAION research dataset is a huge index of online images and captions that's been a source for leading AI image-makers such as Stable Diffusion and Midjourney.
But a report last year by the Stanford Internet Observatory found it contained links to sexually explicit images of children, contributing to the ease with which some AI tools have been able to produce photorealistic deepfakes that depict children.
That December report led LAION, which stands for the nonprofit Large-scale Artificial Intelligence Open Network, to immediately remove its dataset. Eight months later, LAION said in a blog post on Friday that it worked with the Stanford University watchdog group and anti-abuse organisations in Canada and the United Kingdom to fix the problem and release a cleaned-up dataset for future AI research.
Stanford researcher David Thiel, author of the December report, commended LAION for significant improvements but said the next step is to withdraw from distribution the “tainted models” that are still able to produce child abuse imagery.
One of the LAION-based tools that Stanford identified as the “most popular model for generating explicit imagery” - an older and lightly filtered version of Stable Diffusion - remained easily accessible until Thursday, when the New York-based company Runway ML removed it from the AI model repository Hugging Face. Runway said in a statement Friday it was a “planned deprecation of research models and code that have not been actively maintained”.
The cleaned-up version of the LAION dataset comes as governments around the world are taking a closer look at how some tech tools are being used to make or distribute illegal images of children.
San Francisco's city attorney earlier this month filed a lawsuit seeking to shut down a group of websites that enable the creation of AI-generated nudes of women and girls. The alleged distribution of child sexual abuse images on the messaging app Telegram is part of what led French authorities to bring charges on Wednesday against the platform's founder and CEO, Pavel Durov.
Durov's arrest “signals a really big change in the whole tech industry that the founders of these platforms can be held personally responsible,” said David Evan Harris, a researcher at the University of California, Berkeley who recently reached out to Runway asking about why the problematic AI image-generator was still publicly accessible. It was taken down days later.

Commercial LPG hike: Delhi restaurant owners warn of higher menu rates, job losses
New Delhi (PTI) A day after a 50 per cent rise in commercial LPG cylinder prices, Delhi's food business, with restaurant owners and street vendors have warned of higher menu rates, financial strain and potential job losses if the trend persists.
The price of commercial LPG was hiked by a steep Rs 993 per 19 kg cylinder, marking the third consecutive monthly hike amid rising global energy prices linked to the West Asia conflict.
For many in the restaurant industry, the spike has been both sudden and steep.
Manpreet Singh, honorary treasurer of the National Restaurant Association of India, said that eateries are already grappling with supply challenges alongside rising costs.
"There is a huge difficulty in getting these cylinders, and black marketing is also increasing in many unregulated sectors," he said, noting that prices that were once around Rs 1,600, often dropping to nearly Rs 1,300 with discounts, have now surged to between Rs 3,000 and Rs 4,000 per cylinder.
He further added that a medium-sized restaurant typically uses between two and five cylinders daily, making the increase particularly burdensome as costs mount.
Singh further said that as costs mount, smaller establishments could struggle to stay afloat. Instead, the association has advised restaurants to shift towards piped natural gas connections through Indraprastha Gas Limited as a more sustainable alternative.
"If this problem continues, PNG is the only long-term solution," he said, adding that temporary measures like coal offer limited relief due to slower cooking times and that it can largely be used only for tandoors.
Echoing similar concerns, Kabir Suri, owner of Mamagoto in Khan Market, said the impact is already visible across the industry. "There has been almost a threefold increase in cylinder prices for restaurants," he said, adding that rising fuel and logistics costs are compounding the pressure.
"If this continues, it will become a significant financial burden, and food prices will inevitably go up. Adding to this burden, higher fuel costs are also affecting logistics and transportation, making a price rise unavoidable. The extent of the impact will vary between small eateries and large chains depending on their scale," he said.
Global oil prices have surged nearly 50 per cent following disruptions in energy supply chains due to the West Asia conflict, pushing up commercial fuel costs and transport expenses.
A West Delhi-based restaurateur said they are trying to manage rising costs while keeping their staff secure. "We are trying to ensure that our staff, from kitchen workers to waiters, are paid on time and do not face immediate hardship," the owner said.
"We are a small restaurant with seating for about 20 to 25 people at a time. But if this continues for long, we will have to take difficult calls. There is only so much we can absorb, and menu prices will have to go up. We hope this does not continue for a longer period," he said.
Another restaurant owner in North Delhi, who did not wish to be named, said operational adjustments alone may not be enough. "We are checking our costs very carefully and trying to cut wherever possible, but if fuel prices remain high, it will eventually affect how we run the business," the owner said.
"Coal helps in tandoor cooking, but it takes more time," the owner further added.
The strain is even more acute among street vendors, many of whom operate on thin margins. A vendor in Saket said he had recently expanded his business, moving from a mobile cart to a rented outlet.
"I have a family to feed and more responsibilities now. Earlier, I managed with a moving cart, but after renting the place, expenses increased," he said. "Whenever cylinders were unavailable, I had to buy them at higher rates in the black market. Now even regular supply is too expensive, and if this continues, we may have to shut down," he added.
In Laxmi Nagar, another vendor said they are struggling to keep the business running. "Sometimes we even used domestic cylinders from home when supply ran out because we had to keep the stall running," he said, adding that rising costs leave little choice but to increase prices or bear losses.
On April 1, the rates of commercial LPG cylinders were hiked by Rs 195.50 per cylinder, followed by a Rs 114.5 hike on March 1, taking the total increase over the past three months to Rs 1,303. With the latest revision, a 19 kg commercial LPG cylinder now costs Rs 3,371.5 in Delhi, up from Rs 2,078.5 earlier.
The prices of domestic LPG cylinders used for household cooking have remained unchanged. They were last increased by Rs 60 per 14.2 kg cylinder on March 7 and currently cost Rs 913 in Delhi.
