OpenAI Lines Up a $30B Bridge at $1.25T; Microsoft Researchers Crack a 31-Year-Old Math Problem With AI Agents — October 23, 2026

AI Daily Briefing

Summary

Researchers have successfully closed a mathematical problem that remained unsolved since 1995, aided significantly by AI agents. The study involved a control experiment where several leading AI models, without human guidance, failed to reach the solution. This outcome reinforces the importance of human oversight in complex problem-solving, at least for now.

In financial news, OpenAI is reportedly raising up to $30 billion at a valuation of $1.25 trillion, with investors from the UAE leading the round. This funding is seen as a bridge to an initial public offering, as OpenAI seeks to secure more computing capacity to support its ambitious goals. Meanwhile, another AI research lab, DeepSeek, is raising approximately $15 billion, backed by major players in the battery and automotive sectors, highlighting the growing demand for advanced AI capabilities.

Additionally, Microsoft Research details the collaborative efforts of researchers Xin Zhizhang and Zhao Song in proving the Kanan-Lova-Simonovitch conjecture, which has implications for high-dimensional distributions and random walk sampling algorithms. Their work demonstrates the effectiveness of AI tools in enhancing research productivity, as they utilized automated systems to explore and refine their approaches.

Lastly, Recursive has launched a new coding model called Flint, which was developed with significant input from automated research systems. This model aims to improve efficiency in coding tasks, although its performance and reliability are still under evaluation. The ongoing developments in AI research and funding underscore the sector's rapid evolution and the critical role of computational resources.

OpenAI is reportedly closing an up-to-$30 billion round at a $1.25 trillion pre-money valuation, led by UAE investors and Coatue, while efficiency neolab Flapping Airplanes raises $1 billion. Microsoft Research details how human-directed AI agents helped prove the KLS conjecture, and Recursive ships Flint, a 40B open coding model that runs on a laptop.
