OpenAI says it will no longer train its AI models on the live internet, citing “significant risks” and more — today's net signal.
As AI developers continue to push the boundaries of what's possible with machine learning, concerns about safety and responsibility are coming to the forefront. OpenAI's decision to no longer train its AI models on the live internet, citing "significant risks," is a notable example of this shift in thinking. This move comes on the heels of Anthropic's recent acknowledgement of its own challenges, highlighting the difficulties of developing reliable and trustworthy AI systems. These developments suggest that the industry is slowly coming to terms with the complexities of building advanced AI, and that caution is increasingly being exercised to mitigate potential downsides.
Beyond the AI sphere, other startup-related news is also making waves. Carta and NewView have partnered to allow employees to sell shares early, a move that could help address some of the financial pressures faced by startup workers. Meanwhile, the nuclear energy sector is facing its own set of challenges, with a high-profile reactor project encountering problems that are delaying its launch. Against this backdrop, events like the TechCrunch Founder Summit 2026 will provide a platform for founders to discuss the hurdles they're facing and the innovative solutions they're developing. Researchers, too, are working on new tools and approaches, such as LitPivot's dynamic contextualization of literature, that could help drive progress in various fields.
