OpenAI announced that a general‑purpose reasoning model has produced an original proof that overturns a geometry conjecture posed by Paul Erdős in 1946. The company says the breakthrough demonstrates AI’s ability to carry out long, complex chains of reasoning without being tailored for mathematics, a claim that draws both praise from several mathematicians and skepticism after a previous, premature claim by a former OpenAI executive.

Luma AI has introduced Ray3, its first reasoning-based video generation model, now available to users. By allocating more computing time to analyze prompts, Ray3 can handle longer, more complex action sequences than typical AI video tools, which usually produce clips of five to ten seconds. The model includes a visual annotation interface that shows its decision‑making process, a draft mode that creates low‑resolution drafts in about 20 seconds, and the ability to upscale to high‑fidelity 16‑bit HDR video in two to five minutes. Ray3 joins a growing field of generative video tools from companies like Midjourney and Google’s Veo 3, while also raising ongoing concerns about AI‑generated media and artist lawsuits. Lire la suite
