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.

44 peacocks die of H5N1 in Karnataka’s Tumakuru; minister orders precautions
Bengaluru (PTI): After 44 peacocks died of the H5N1 virus in Tumakuru district, Karnataka Minister Eshwar Khandre on Saturday directed officials to implement strict precautionary measures to prevent its spread across forest areas, including zoos and bird sanctuaries.
The directive comes after laboratory reports from the ICAR–National Institute of High Security Animal Diseases in Bhopal recently confirmed H5N1 avian influenza as the cause of the deaths.
According to the state forest minister, the peacocks died between April 16 and 21 in and around Bommanahalli and Kolihalli villages in Urdigere hobli, and Bairasandra and Hullenahalli villages in Gulur hobli of Tumakuru district.
“In this context, instructions have been issued in line with the revised H5N1 Action Plan of the Central Government to prevent the spread of infection across all forest areas, including zoos, bird sanctuaries, Magadi Lake, and the community reserve at Kokkare Bellur,” Khandre said in a note addressed to the principal chief conservator of forests (wildlife) and chief wildlife warden.
He also directed that any deaths of birds, whether migratory or local, must be reported immediately, and that samples from carcasses should be collected and sent for testing.
If required, a nodal officer may be appointed to monitor the situation across the state, he added.
Authorities have established an infected zone within a 0–3 km radius and a surveillance zone extending from 3 to 10 km.
According to the Health Department, surveillance for fever, Influenza-Like Illness (ILI), and Severe Acute Respiratory Infection (SARI) will be carried out over the next 10 days, covering a population of 20,432 across 38 villages.
In light of the situation, the department has advised the public to follow precautionary measures to minimise the risk of infection by avoiding contact with sick or dead birds and maintaining hand hygiene by washing hands frequently with soap and water.
It has also suggested the use of personal protective equipment (PPE) while handling birds or their droppings, and advised ensuring that poultry and eggs are thoroughly cooked (above 80 degrees celcius) before consumption.
The health department has also recommended avoiding close contact with individuals exhibiting symptoms of respiratory illness.
The department said it is closely monitoring the situation and has put necessary precautionary measures in place.
The public has been advised to remain vigilant and report any unusual bird deaths or symptoms promptly, officials added.
Avian influenza (H5N1) is a subtype of the influenza virus that infects birds and mammals, including humans in rare instances, according to the World Health Organisation. Human cases reported so far have been mostly linked to close contact with infected birds or other animals, or with contaminated environments.
