Mira Murati's Thinking Machines Lab and Bridgewater, the world's largest hedge fund, published joint results on using AI for a basic but important task in investing: Deciding which news deserves an analyst's attention. First, Bridgewater tried the frontier models. GPT, Claude, and Gemini variants averaged around 50% across six filtering tests. Then, expert investors wrote the prompts themselves. Accuracy climbed into the mid-70s. Still shy of the 80% the investors said they'd need before trusting a system in daily work. Then came the fine-tune using TML's Tinker API, with Bridgewater training an open-weight model on its experts' real judgement calls. The results: 84.7%, with mistakes down 29.8% versus the top frontier model tested, and at a 13.8x lower per-task cost. Murati, on X: "Experts improving AI that empowers experts."
