Today, we share a breakthrough on the planar unit distance problem, a famous open question first posed by Paul Erdős in 1946. For nearly 80 years, mathematicians believed the best possible solutions looked roughly like square grids. An OpenAI model has now disproved that belief, discovering an entirely new family of constructions that performs better. This marks the first time AI has autonomously solved a prominent open problem central to a field of mathematics.

We’re adding new ways for people to identify AI-generated images and understand where they came from. In addition to C2PA Content Credentials, images now also contain a SynthID watermark, and can be identified using a public verification tool to check whether an image was made by OpenAI products. openai.com/index/advancing-c…

Pi Day is almost ending (already did if you look at UTC time, but there are a few more hours in US), so I just squeezed in an article about some geometries where pi is 2, 3, or 4. There were hints on my blog about this and now I have more qs for follow-ups mihai.page/pi-2026/
