According to CoinMeta, Coinbase CEO Brian Armstrong stated that the company has fine-tuned Alibaba's open-source weight model Qwen3.5-9b using internal proprietary data, resulting in performance that surpasses that of leading large models in the specific task of fraud prevention, while also being more cost-effective and running faster. Armstrong believes that in the future, enterprises will increasingly adopt specialized models optimized for specific tasks. Coinbase is providing its employees with tools for fine-tuning internal models and exploring the possibility of using this architecture to completely replace some backend services.
