New ChatGPT model reduces unsafe replies by up to 80%

OpenAI has updated ChatGPT’s default model after working with more than 170 mental health clinicians to help the system better spot distress, de-escalate conversations and point users to real-world support.

The update routes sensitive exchanges to safer models, expands access to crisis hotlines and adds gentle prompts to take breaks, aiming to reduce harmful responses rather than simply offering more content.

Measured improvements are significant across three priority areas: severe mental health symptoms such as psychosis and mania, self-harm and suicide, and unhealthy emotional reliance on AI.

OpenAI reports that undesired responses fell between 65 and 80 percent in production traffic and that independent clinician reviews show significant gains compared with earlier models. At the same time, rare but high-risk scenarios remain a focus for further testing.

The company used a five-step process to shape the changes: define harms, measure them, validate approaches with experts, mitigate risks through post-training and product updates, and keep iterating.

Evaluations combine real-world traffic estimates with structured adversarial tests, so better ChatGPT safeguards are in place now, and further refinements are planned as understanding and measurement methods evolve.

Samsung and SoftBank team up on AI-RAN for next-gen telecom

Samsung Electronics and SoftBank Corp. have collaborated to develop advanced AI-RAN technologies to enhance next-generation telecommunications infrastructure.

The partnership will combine Samsung’s expertise in network solutions with SoftBank’s extensive operational data to advance automation and intelligence in wireless networks.

The companies plan to explore how AI can optimise network efficiency, improve real-time decision-making, and dynamically manage radio resources to deliver faster, more reliable connections. AI-RAN technologies are expected to play a key role in the evolution of 6G networks, where managing complex data flows and ensuring energy-efficient operations will become essential.

Dr Junehee Lee, Executive Vice President at Samsung Electronics, said the collaboration represents ‘an important step toward realising autonomous networks powered by AI.’ He noted that such systems can predict network conditions, self-adjust to maintain quality of service, and reduce human intervention in operations.

Junichi Miyakawa, President and CEO of SoftBank, emphasised that the project aligns with SoftBank’s long-term vision to build smarter, more resilient telecommunications infrastructure. ‘By combining our operational insights with Samsung’s technology leadership, we aim to accelerate innovation in network automation and deliver superior experiences to users,’ he said.

The two companies will begin joint trials in Japan using Samsung’s virtualised RAN (vRAN) and Open RAN solutions. These trials will focus on applying machine learning models to radio network optimisation, particularly in urban environments with high data demand.

Both firms view AI-RAN as a foundation for future communications systems that can autonomously adapt to network load and interference, setting the stage for a new generation of intelligent, energy-efficient mobile connectivity.

UN cybercrime treaty signed in Hanoi amid rights concerns

Around 60 countries signed a landmark UN cybercrime convention in Hanoi, seeking faster cooperation against online crime. Leaders cited trillions in annual losses from scams, ransomware, and trafficking. The pact enters into force after 40 ratifications.

UN supporters say the treaty will streamline evidence sharing, extradition requests, and joint investigations. Provisions target phishing, ransomware, online exploitation, and hate speech. Backers frame the deal as a boost to global security.

Critics warn the text’s breadth could criminalise security research and dissent. The Cybersecurity Tech Accord called it a surveillance treaty. Activists fear expansive data sharing with weak safeguards.

The UNODC argues the agreement includes rights protections and space for legitimate research. Officials say oversight and due process remain essential. Implementation choices will decide outcomes on the ground.

The EU, Canada, and Russia signed in Hanoi, underscoring geopolitical buy-in. Vietnam, being the host, drew scrutiny over censorship and arrests. Officials there cast the treaty as a step toward resilience and stature.

Church of Greece launches AI tool LOGOS for believers

LOGOS, a digital tool developed by the Metropolis of Nea Ionia, Filadelfia, Iraklio and Halkidona alongside the University of the Aegean, has marked the Church of Greece’s entry into the age of AI.

The tool gathers information on questions of Christian faith and provides clear, practical answers instead of replacing human guidance.

Metropolitan Gabriel, who initiated the project, emphasised that LOGOS does not substitute priests but acts as a guide, bringing believers closer to the Church. He said the Church must engage the digital world, insisting that technology should serve humanity instead of the other way around.

An AI tool that also supports younger users, allowing them to safely access accurate information on Orthodox teachings and counter misleading or harmful content found online. While it cannot receive confessions, it offers prayers and guidance to prepare believers spiritually.

The Church views LOGOS as part of a broader strategy to embrace digital tools responsibly, ensuring that faith remains accessible and meaningful in the modern technological landscape.

AI deepfake videos spark ethical and environmental concerns

Deepfake videos created by AI platforms like OpenAI’s Sora have gone viral, generating hyper-realistic clips of deceased celebrities and historical figures in often offensive scenarios.

Families of figures like Dr Martin Luther King Jr have publicly appealed to AI firms to prevent using their loved ones’ likenesses, highlighting ethical concerns around the technology.

Beyond the emotional impact, Dr Kevin Grecksch of Oxford University warns that producing deepfakes carries a significant environmental footprint. Instead of occurring on phones, video generation happens in data centres that consume vast amounts of electricity and water for cooling, often at industrial scales.

The surge in deepfake content has been rapid, with Sora downloaded over a million times in five days. Dr Grecksch urges users to consider the environmental cost, suggesting more integrated thinking about where data centres are built and how they are cooled to minimise their impact.

As governments promote AI growth areas like South Oxfordshire, questions remain over sustainable infrastructure. Users are encouraged to balance technological enthusiasm with environmental mindfulness, recognising the hidden costs behind creating and sharing AI-generated media.

EU investigates Meta and TikTok for DSA breaches

The European Commission has accused Meta and TikTok of breaching the Digital Services Act (DSA), highlighting failures in handling illegal content and providing researchers access to public data.

Meta’s Facebook and Instagram were found to make it too difficult for users to report illegal content or receive responses to complaints, the Commission said in its preliminary findings.

Investigations began after complaints to Ireland’s content regulator, where Meta’s EU base is located. The Commission’s inquiry, which has been ongoing since last year, aims to ensure that large platforms protect users and meet EU safety obligations.

Meta and TikTok can submit counterarguments before penalties of up to six percent of global annual turnover are imposed.

Both companies face separate concerns about denying researchers adequate access to platform data and preventing oversight of systemic online risks. TikTok is under further examination for minor protection and advertising transparency issues.

The Commission has launched 14 such DSA-related proceedings, none concluded.

Australia demands answers from AI chatbot providers over child safety

Australia’s eSafety Commissioner has issued legal notices to four major AI companion platforms, requiring them to explain how they are protecting children from harmful or explicit content.

Character.ai, Nomi, Chai, and Chub.ai were all served under the country’s Online Safety Act and must demonstrate compliance with Australia’s Basic Online Safety Expectations.

The notices follow growing concern that AI companions, designed for friendship and emotional support, can expose minors to sexualised conversations, suicidal ideation, and other psychological risks.

eSafety Commissioner Julie Inman Grant said the companies must show how their systems prevent such harms, not merely react to them, warning that failure to comply could lead to penalties of up to $825,000 per day.

AI companion chatbots have surged in popularity among young users, with Character.ai alone attracting nearly 160,000 monthly active users in Australia.

The Commissioner stressed that these services must integrate safety measures by design, as new enforceable codes now extend to AI platforms that previously operated with minimal oversight.

A move that comes amid wider efforts to regulate emerging AI technologies and ensure stronger child protection standards online.

Breaches of the new codes could result in civil penalties of up to $49.5 million, marking one of the toughest online safety enforcement regimes globally.
