OpenAI launched GPT Image 1.5, delivering 4x faster image generation and improved editing accuracy for ChatGPT and API users worldwide. PCWorld reports the update includes a new creative studio mode with an image tab for enhanced editing capabilities and filter applications. The accelerated release aims to compete with Google's recent AI advancements while addressing consistency issues in consecutive image adjustments. OpenAI has launched its newest image model GPT Image 1.5, which offers up to 4 times faster image generation, more accurate image editing, and better compliance with user instructions. One of the more noticeable improvements is that the new version should provide more consistent results between consecutive edits. For example, when adjusting lighting, facial expressions, or color tone on a specific image, GPT Image should no longer make drastic unwanted changes--something many AI image tools have difficulty with.

W hen the billionaire chief executive of AI chipmaker Nvidia threw a party in central London for Donald Trump's state visit in September, the power imbalance between Silicon Valley and British politicians was vividly exposed. Jensen Huang hastened to the stage after meetings at Chequers and rallied his hundreds of guests to cheer on the power of AI. In front of a huge Nvidia logo, he urged the venture capitalists before him to herald "a new industrial revolution", announced billions of pounds in AI investments and, like Willy Wonka handing out golden tickets, singled out some lucky recipients in the room. "If you want to get rich, this is where you want to be," he declared. But his biggest party trick was a surprise guest waiting in the wings.

Google's Gemini 3 Flash model outperforms GPT-5.2 in some benchmarks Gemini 3 Flash is now rolling out to the Gemini app and AI Mode in Search. Almost exactly a month after the debut of Gemini 3 Pro in November, Google has begun rolling out the more efficient Flash version of its latest AI model. According to the company, the new system offers similar pro-grade reasoning performance as its flagship model at a fraction of the cost, making it ideal for everyday use. In benchmarks, the new system performed significantly better than Google's previous generation models, including Gemini 2.5 Pro. More notably, in Google's testing it managed to trade blows with GPT-5.2, the model OpenAI rushed out to counter Gemini 3 Pro.

OpenAI is planning to spend $1.4tn on AI infrastructure over the next eight years. OpenAI is planning to spend $1.4tn on AI infrastructure over the next eight years. Amazon is in talks to invest more than $10bn (£7.5bn) in OpenAI, in the latest funding deal being struck by the startup behind ChatGPT . If it goes ahead, the market valuation of OpenAI could rise above $500bn, according to The Information, a tech news site that revealed the negotiations . Amazon, which is best known as an online retailer, is also the world's largest datacentre provider and its investment would help OpenAI pay for its commitments to rent capacity from cloud computing companies - including Amazon .

OpenAI would also rent more data center capacity from Amazon. Amazon is in discussions with OpenAI to invest $10 billion in the company while supplying more of its AI chips and cloud computing services, according to . The deal would push OpenAI's valuation over $500 billion but is likely to raise more questions about the company's circular investment agreements involving chips and data centers. The two companies are also in talks about the possibility of OpenAI helping Amazon with its online marketplace, similar to deals it has made with Etsy, Shopify and Instacart. However, any agreement still wouldn't allow Amazon to market OpenAI's most advanced models on its developer cloud platform, as Microsoft holds the exclusive rights to those until the 2030s.

Former chancellor George Osborne is joining artificial intelligence (AI) giant OpenAI. He will lead its OpenAI for Countries programme, which is aimed at helping governments increase their AI capacity. Announcing his new London-based role, Osborne said it was a privilege to be joining the company. I recently asked myself the question: what's the most exciting and promising company in the world right now? The answer I believe is OpenAI, he said on X.

Plus, there's a new dedicated sidebar with presets and prompt suggestions. ChatGPT is available on both iOS and Android. Following the release of GPT-5.2 last week, OpenAI has begun rolling out a new image generation model . The company says the updated ChatGPT Images is four times faster than its predecessor. If you're a frequent ChatGPT user, you'll know it can sometimes take a while for OpenAI's servers to create images, particularly during peak times and if you're not paying for ChatGPT Plus.

As OpenAI scrambles to improve ChatGPT, it's ditching a feature in its free tier that contributed to last summer's user revolt. OpenAI has quietly reversed a major change to how hundreds of millions of people use ChatGPT . On a low-profile blog that tracks product changes, the company said that it rolled back ChatGPT's model router--an automated system that sends complicated user questions to more advanced "reasoning" models--for users on its Free and $5-a-month Go tiers. Instead, those users will now default to GPT-5.2 Instant, the fastest and cheapest-to-serve version of OpenAI's new model series. Free and Go users will still be able to access reasoning models, but they will have to select them manually.

AI Is Getting Better at Science. Demis Hassabis founded DeepMind to "solve intelligence" and then use that to "solve everything else." Sam Altman promised that "the gains to quality of life from AI driving faster scientific progress will be enormous." Dario Amodei of Anthropic predicted that as soon as 2026, AI progress could produce a "country of geniuses in a data center." Of all the foundational myths driving the AI boom, the hope that AI might help humanity understand the universe is among the most enduring. FrontierScience, a new benchmark published Tuesday by OpenAI, suggests that AI models are advancing toward that goal--and highlights the difficulty of testing models' capabilities as they become ever more competitive with human scientists.
