OpenAI has reportedly achieved a significant breakthrough by using a publicly available model, GPT-5.6 Sol Ultra, to solve a 50-year-old unsolved math problem. This model, reportedly utilizing 64 subagents, accomplished the proof in under an hour. This development is notable as most recent major math breakthroughs have involved experimental large language models, not public ones. Separately, there are reports of Apple suing over IP theft related to a new AI hardware venture involving former iPhone designer Jonny Ive and Sam Altman, who is associated with OpenAI. AI
