1. OpenAI announces ChatGPT access now without an account

OpenAI has announced that users will no longer need an account to use its popular AI conversation platform, ChatGPT. However, other products like DALL-E 3 will still require an account for access. The company is rolling out this change gradually to make AI accessible to anyone interested in its capabilities.

ChatGPT has a global user base of over 100 million individuals across 185 countries and remains the most frequented AI chatbot site. OpenAI has implemented additional content safeguards to limit prompts and allows users to opt out of model training, even without accounts.

2. U.S., U.K. Announce Partnership to Safety Test AI Models

The UK and US have announced a partnership to work together on safety testing powerful artificial intelligence models. The agreement, signed by UK Secretary of State for Science, Innovation and Technology Michelle Donelan and US Secretary of Commerce Gina Raimondo, sets out a plan for collaboration between the two governments.

The two AI safety testing bodies will develop a common approach to AI safety testing, using the same methods and underlying infrastructure. The institutes intend to perform a joint testing exercise on an AI model available to the public.

3. Data centre power use 'to surge six-fold in 10 years'

The National Grid predicts that the rise in AI and quantum computing will lead to a six-fold increase in data centre power use in the next decade. The power these data centres use will be constrained, and bold action is needed to create a network capable of coping with growing demand.

The National Grid boss believes that the current high-voltage transmission network is over 70 years old and is under pressure to upgrade to meet higher consumer demand for electricity sustainably by connecting to renewable energy sources. Data centres will be integral to the future of the grid, but they come at an environmental cost, with some studies warning that the AI industry could consume as much energy as a country the size of the Netherlands by 2027.

4. Alzheimer’s Drug Fermented With Help From AI and Bacteria Moves Closer to Reality

Researchers at The University of Texas at Austin have developed an innovative approach using artificial intelligence and biosensors to accelerate drug development. They have genetically modified bacteria to create a chemical precursor of galantamine as a byproduct of their normal cellular metabolism.

The bacteria are programmed to convert food into medicinal compounds, creating a reliable supply that is less expensive to produce. The process of harnessing microbes to produce useful byproducts is relatively new, but applying AI in the process expands what is possible with microbial fermentation.

5. AI companies running out of training data after burning through entire internet

AI companies are facing a mass shortage of data as the internet becomes too small to provide all the necessary data. As a result, some companies are exploring alternative sources of data training, such as publicly-available video transcripts and AI-generated synthetic data. OpenAI has discussed training GPT-5 on transcriptions from public YouTube videos, while Anthropic, a company formed by OpenAI, is aiming to create a safer and more ethical AI.

However, concerns about AI running out of data have been spooking researchers for some time. Researchers believe that the biggest uncertainty is what breakthroughs will be made. Another solution is for AI companies to stop trying to create bigger and better models, as they also use electricity and expensive computing chips that require mining rare-earth minerals.
