this is one of those space images that’s “so beautiful it looks like a painting” 🌌
A spiral galaxy seen at a skewed angle. Its centre is a bright spot radiating light. A thick, stormy disc of material surrounds this, with swirling strands of dark dust and bright spots of star formation strewn through the disc. A large spiral arm extends from the disc towards the viewer. Some foreground stars are visible atop the galaxy.

OpenAI’s so-called “reasoning” models generate more falsehoods than their predecessors. Since #LLMs are model language usage and not factual information, it’s built-into their design that they will output false or misleading information. #PhilAI techcrunch.com/2025/04/18/o...
OpenAl found that o3 hallucinated in response to 33% of questions on PersonQA, the company's in-house benchmark for measuring the accuracy of a model's knowledge about people. That's roughly double the hallucination rate of OpenAl's previous reasoning models, o1 and o3-mini, which scored 16% and 14.8%, respectively. o4-mini did even worse on PersonQA - hallucinating 48% of the time.
