Bridgewater Associates joint research: frontier AI model financial judgment accuracy only 50-70%, fine-tuned open-source model reaches 84.7%

Bridgewater Associates joint research team testing found that frontier large models such as GPT and Claude have only about 50% accuracy on basic financial information screening tasks, and only 70% after optimization, not reaching the 80% credible threshold. Meanwhile, a self-developed model fine-tuned from open-source models achieved 84.7% accuracy, at only one-fourteenth the cost of frontier models.
