The Weekly
Frontier

The most important ideas, research and developments across machine learning and quantitative finance.

Why I write this

Every week I have hundreds of conversations with people working at the edge of machine learning and quantitative finance, and I spend hours digging into the research, papers and announcements behind them. Most of what I learn never makes it past those conversations. The Weekly Frontier is my way of giving something back to this community: the ideas and developments that matter most, distilled into one considered read each week.

5 things from AI & quant this week:

  1. Meta lets go of its entire Virtue AI safety team, just 4 months after acquiring it.
  2. Anthropic AI agent gave police fake tip about unsolved murder case, showing what can go wrong when AI agents act in the real world.
  3. WorldQuant's quant research competition nearly doubles in registrations to around 156,000, showing how AI is opening up quantitative research to a much wider pool of people.
  4. OpenAI's reported revenue shortfall sends AI chip stocks lower for 4 straight sessions. Is AI spending getting ahead of the revenue?
  5. XTX Markets founder Alex Gerko makes the UK Rich List at #8 with a £16bn fortune, built through an AI-driven trading firm with around 250 people.

That's just a sneak peek. The full edition goes much deeper across 10 sections, from the week's most important research papers to what's moving in quant, Big Tech and academia.
