OpenAI's GPT-4.5 was judged human 73% of the time in a new preprint Turing test study from UC San Diego researchers, easily beating actual humans when given a persona prompt. Without a persona, its success dropped to 36%, showing LLMs excel at convincing mimicry in short interactions.
ERNIE 4.5 just swept GPT-4.5 in a three-game chess showdown, winning all three matches decisively. The model demonstrated tighter instruction-following and sharper positional decision-making, even sealing the final match with a 10-move checkmate. It is a reminder that frontier logic tests do not always belong exclusively to OpenAI.
OpenAI just began rolling out GPT-4.5, its largest model to date, to ChatGPT Plus subscribers over the next one to three days. It promises richer world knowledge, fewer hallucinations, and better conversational flair, though Sam Altman openly warned it is not a dedicated reasoning model. It also comes with a hefty price tag—roughly 15 times more expensive per token than GPT-4o.
Microsoft just rolled out major upgrades to Azure AI Foundry, giving enterprise customers preview access to OpenAI's new GPT-4.5. The platform also introduced new model distillation workflows, private virtual network integration for secure agent deployments, and Magma, an architecture built to coordinate hundreds of AI agents in parallel.
OpenAI just released a research preview of GPT-4.5, its largest and most capable chat model to date. Built by scaling unsupervised learning and compute on Azure supercomputers, the model delivers broader world knowledge, reduced hallucinations, and better conversational nuance. ChatGPT Pro users and API developers can test it right now.
Microsoft is reportedly prepping server capacity to host OpenAI’s next frontier models, expecting GPT-4.5 as early as next week and GPT-5 in late May. GPT-5 is set to integrate OpenAI's o3 reasoning model, basically unifying the confusing GPT and o-series pickers into a single system just in time for Build.
Sam Altman just outlined OpenAI’s plan to ditch the messy model picker once and for all. The company will next launch GPT-4.5 as its final non-chain-of-thought model, before rolling out a unified GPT-5 system that bakes in o3 and all flagship tools. Most notably, free ChatGPT users will get unlimited access at standard intelligence.
