OpenAI Publishes "Our Principles" AGI Manifesto

Sam Altman published OpenAI's five guiding principles for navigating the path to AGI, acknowledging the company deserves "enormous scrutiny" and committing to course correction when wrong. The five principles:

Democratization — Resist power consolidation; give everyone access to AI; ensure democratic governance of key decisions
Empowerment — Enable people to achieve goals with broad latitude, while minimizing catastrophic harm and erring on the side of caution
Universal Prosperity — Massive AI infrastructure required so everyone can participate in value creation; governments may need new economic models
Resilience — Collaborative society-wide solutions for new risks including pathogens and cyber threats; willingness to pause development if necessary
Adaptability — Update positions as new information emerges; transparent about trade-offs between empowerment and resilience

"It wasn't that long ago that we were nervous about releasing the weights of GPT-2 because we weren't sure what the impacts on society will be. Obviously in retrospect that was a misplaced worry, but it led to us discovering the strategy of iterative deployment, which has been one of the most important things we've figured out." — Sam Altman

Amateur Solves 60-Year Erdős Problem Using ChatGPT

Liam Price, a 23-year-old amateur with no advanced mathematics training, used a single prompt to GPT-5.4 Pro (via ChatGPT Pro) to solve a 60-year-old mathematical conjecture by Paul Erdős on primitive sets. The problem had stumped world-class mathematicians including Terence Tao and Jared Lichtman.

The LLM applied a well-known formula from related areas of mathematics that no human had thought to apply to this specific question
Terence Tao: "The humans that looked at it just collectively made a slight wrong turn at move one... there was some kind of mental block"
Lichtman and Tao subsequently formalized the proof, distilling the LLM's key insight
The achievement highlights a potential collaborative model: amateurs with AI access identifying solutions, combined with expert mathematicians refining and validating outputs
Unlike recent AI math headlines, experts say this result is genuinely novel
