GPT-4o set for retirement as OpenAI shifts focus to newer systems

OpenAI has confirmed that several legacy AI models will be removed from ChatGPT, with GPT-4o scheduled for retirement on 13 February. The decision follows months of debate after the company reinstated the model amid strong user backlash.

Alongside GPT-4o, the models being withdrawn include GPT-5 Instant, GPT-5 Thinking, GPT-4.1, GPT-4.1 mini, and o4-mini. The changes apply only to ChatGPT, while developers will continue to access the models through OpenAI’s API.

GPT-4o had built a loyal following for its natural writing style and emotional awareness, with many users arguing newer models felt less expressive. When OpenAI first attempted to phase it out in 2025, widespread criticism prompted a temporary reversal.

Company data now suggests active use of GPT-4o has dropped to around 0.1% of daily users. OpenAI says features associated with the model have since been integrated into GPT-5.2, including personality tuning and creative response controls.

Despite this, criticism has resurfaced across social platforms, with users questioning usage metrics and highlighting that GPT-4o was no longer prominently accessible. Comments from OpenAI leadership acknowledging recent declines in writing quality have further fuelled concerns about the model’s removal.

AI news needs ‘nutrition labels’, UK think tank says amid concerns over gatekeepers

A leading British think tank has urged the government to introduce ‘nutrition labels’ for AI-generated news, arguing that clearer rules are needed as AI becomes a dominant source of information.

The Institute for Public Policy Research said AI firms are increasingly acting as new gatekeepers of the internet and must pay publishers for the journalism that shapes their output.

The group recommended standardised labels showing which sources underpin AI-generated answers, instead of leaving users unsure about the origin or reliability of the material they read.

It also called for a formal licensing system in the UK that would allow publishers to negotiate directly with technology companies over the use of their content. The move comes as a growing share of the public turns to AI for news, while Google’s AI summaries reach billions each month.

IPPR’s study found that some AI platforms rely heavily on content from outlets with licensing agreements, such as the Guardian and the Financial Times, while others, like the BBC, appear far less often due to restrictions on scraping.

The think tank warned that such patterns could weaken media plurality by sidelining local and smaller publishers instead of supporting a balanced ecosystem. It added that Google’s search summaries have already reduced traffic to news websites by providing answers before users click through.

The report said public funding should help sustain investigative and local journalism as AI tools expand. OpenAI responded that its products highlight sources and provide links to publishers, arguing that careful design can strengthen trust in the information people see online.

MIT develops compact ultrasound system for frequent breast cancer screening

Massachusetts Institute of Technology researchers have developed a compact ultrasound system designed to make breast cancer screening more accessible and frequent, particularly for people at higher risk.

The portable device could be used in doctors’ offices or at home, helping detect tumours earlier than current screening schedules allow.

The system pairs a small ultrasound probe with a lightweight processing unit to deliver real-time 3D images via a laptop. Researchers say its portability and low power use could improve access in rural areas where traditional ultrasound machines are impractical.

Frequent monitoring is critical, as aggressive interval cancers can develop between routine mammograms and account for up to 30% of breast cancer cases.

By enabling regular ultrasound scans without specialised technicians or bulky equipment, the technology could increase early detection rates, where survival outcomes are significantly higher.

Initial testing successfully produced clear, gap-free 3D images of breast tissue, and larger clinical trials are now underway at partner hospitals. The team is developing a smaller version that could connect to a smartphone and be integrated into a wearable device for home use.

Best moments from MoltBook archives

A new ‘Best of MoltBook’ post on Astral Codex Ten has renewed debate over how AI-assisted writing is being presented and understood. The collection highlights selected excerpts from MoltBook, a public notebook used to explore ideas with the help of AI tools.

MoltBook is framed as a space for experimentation rather than finished analysis, with short-form entries reflecting drafts, prompts and revisions. Human judgement remains central, with outputs curated, edited or discarded rather than treated as autonomous reasoning.

Some readers have questioned descriptions of the work as ‘agentic AI’, arguing the label exaggerates the technology’s role. The AI involved responds to instructions but does not act independently, plan goals or retain long-term memory.

The discussion reflects wider scepticism about inflated claims around AI capability. MoltBook is increasingly viewed as an example of AI as a productivity aid for thinking, rather than evidence of a new form of independent intelligence.

Chinese court limits liability for AI hallucinations

A court in China has ruled that AI developers are not automatically liable for hallucinations produced by their systems. The decision was issued by the Hangzhou Internet Court in eastern China and sets an early legal precedent.

Judges found that AI-generated content should be treated as a service rather than a product in such cases. In China, users must therefore prove developer fault and show concrete harm caused by the erroneous output.

The case involved a user in China who relied on AI-generated information about a university campus that did not exist. The court ruled no damages were owed, citing a lack of demonstrable harm and no authorisation for the AI to make binding promises.

The Hangzhou Internet Court warned that strict liability could hinder innovation in China’s AI sector. Legal experts say the ruling clarifies expectations for developers while reinforcing the need for user warnings about AI limitations.

Grok returns to Indonesia as X agrees to tightened oversight

Indonesia has restored access to Grok after receiving guarantees from X that stronger safeguards will be introduced to prevent further misuse of the AI tool.

Authorities suspended the service last month following the spread of sexualised images on the platform, making Indonesia the first country to block the system.

Officials from the Ministry of Communications and Digital Affairs said that access had been reinstated on a conditional basis after X submitted a written commitment outlining concrete measures to strengthen compliance with national law.

The ministry emphasised that the document serves as a starting point for evaluation instead of signalling the end of supervision.

However, the government warned that restrictions could return if Grok fails to meet local standards or if new violations emerge. Indonesian regulators stressed that monitoring would remain continuous, and access could be withdrawn immediately should inconsistencies be detected.

The decision marks a cautious reopening rather than a full reinstatement, reflecting Indonesia’s wider efforts to demand greater accountability from global platforms deploying advanced AI systems within its borders.

Why smaller AI models may be the smarter choice

Most everyday jobs do not actually need the most powerful, cutting-edge AI models, argues Jovan Kurbalija in his blog post ‘Do we really need frontier AI for everyday work?’. While frontier AI systems dominate headlines with ever-growing capabilities, their real-world value for routine professional tasks is often limited. For many people, much of daily work remains simple, repetitive, and predictable.

Kurbalija points out that large parts of professional life, from administration and law to healthcare and corporate management, operate within narrow linguistic and cognitive boundaries. Daily communication relies on a small working vocabulary, and most decision-making follows familiar mental patterns.

In this context, highly complex AI models are often unnecessary. Smaller, specialised systems can handle these tasks more efficiently, at lower cost and with fewer risks.

Using frontier AI for routine work, the author suggests, is like using a sledgehammer to crack a nut. These large models are designed to handle almost anything, but that breadth comes with higher costs, heavier governance requirements, and stronger dependence on major technology platforms.

In contrast, small language models tailored to specific tasks or organisations can be faster, cheaper, and easier to control, while still delivering strong results.

Kurbalija compares this to professional expertise itself. Most jobs never required having the Encyclopaedia Britannica open on the desk. Real expertise lives in procedures, institutions, and communities, not in massive collections of general knowledge.

Similarly, the most useful AI tools are often those designed to draft standard documents, summarise meetings, classify requests, or answer questions based on a defined body of organisational knowledge.

Diplomacy, an area Kurbalija knows well, illustrates both the strengths and limits of AI. Many diplomatic tasks are highly ritualised and can be automated using rules-based systems or smaller models. But core diplomatic skills, such as negotiation, persuasion, empathy, and trust-building, remain deeply human and resistant to automation. The lesson, he argues, is to automate routines while recognising where AI should stop.

The broader paradox is that large AI platforms may benefit more from users than users benefit from frontier AI. By sitting at the centre of workflows, these platforms collect valuable data and organisational knowledge, even when their advanced capabilities are not truly needed.

As Kurbalija concludes, a more common-sense approach would prioritise smaller, specialised models for everyday work, reserving frontier AI for genuinely complex tasks, and moving beyond the assumption that bigger AI is always better.

Education and rights central to UN AI strategy

UN experts are intensifying efforts to shape a people-first approach to AI, warning that unchecked adoption could deepen inequality and disrupt labour markets. AI offers productivity gains, but benefits must outweigh social and economic risks, the organisation says.

UN Secretary-General António Guterres has repeatedly stressed that human oversight must remain central to AI decision-making. UN efforts now focus on ethical governance, drawing on the Global Digital Compact to align AI with human rights.

Education sits at the heart of the strategy. UNESCO has warned against prioritising technology investment over teachers, arguing that AI literacy should support, not replace, human development.

Labour impacts also feature prominently, with the International Labour Organization predicting widespread job transformation rather than inevitable net losses.

Access and rights remain key concerns. The UN has cautioned that AI dominance by a small group of technology firms could widen global divides, while calling for international cooperation to regulate harmful uses, protect dignity, and ensure the technology serves society as a whole.

Mining margins collapse amid falling Bitcoin prices

CryptoQuant data shows Bitcoin mining profitability has fallen to its weakest level in 14 months, as declining prices and rising operational pressure weigh on the sector. The miner profit and loss sustainability index dropped to 21, its lowest reading since November 2024.

Lower Bitcoin prices and elevated mining difficulty have left operators ‘extremely underpaid’, according to the report. Network hash rate has also declined across five consecutive epochs, reaching its lowest level since September 2025 and signalling reduced computing power securing the network.

Severe winter weather across parts of the eastern United States added further strain, disrupting mining activity and pushing daily revenues down to around $28 million, a yearly low. Weaker risk appetite across equities and digital assets has compounded the impact.

Shares in listed miners such as MARA Holdings, CleanSpark, and Riot Holdings have fallen by double-digit percentages over the past week. Data from the Cambridge Bitcoin Electricity Consumption Index shows mining BTC now costs more than buying it on the open market, increasing pressure on weaker operators.

Google launches AlphaGenome AI tool

Google has unveiled AlphaGenome, a new AI research tool designed to analyse the human genome and uncover the genetic roots of disease. The announcement was made in Paris, where researchers described the model as a major step forward.

AlphaGenome focuses on non-coding DNA, which makes up most of the human genome and plays a key role in regulating genes. Google scientists in Paris said the system can analyse extremely long DNA sequences at high resolution.

The model was developed by Google DeepMind using public genomic datasets from humans and mice. Researchers in Paris said the tool predicts how genetic changes influence biological processes inside cells.

Independent experts in the UK welcomed the advance but urged caution. Scientists at University of Cambridge and the Francis Crick Institute noted that environmental factors still limit what AI models can explain.
