Noam Brown is a researcher who speaks publicly on AI research and disputes on X. Recently he responded to Levent’s plagiarism accusations urging AnthropicAI colleagues to address them, clarified that the model used did not rely on Levent’s or Tristan’s prompts (citing Sebastien Bubeck), and discussed compute costs—saying the result cost millions and comparing OpenAI o3’s ~$500,000 ARC-AGI score with Astra’s ~$20 accessibility and work with GDM and IMO.

I understand how, looking at today’s LLMs, people might think the only way we'd achieve NS is by using Levent’s/Tristan’s prompts. But I hope this plot conveys the model used is a huge step up from today’s LLMs. Nobody looked at Levent’s/Tristan’s prompts. Th…

Yes, this result cost millions of dollars. But remember that when @OpenAI announced o3 it cost ~$500,000 to score 87.5% on ARC-AGI 1. Today, Astra scores higher for ~$20. In 2025 it took us and GDM an enormous amount of compute to achieve IMO gold. For the 20…
