Introducing Ripple-65B Preview, a Frontier Open-Weight Model Ricursive Intelligence is a full-stack artificial intelligence lab building self-improving systems by co-optimizing hardware, software, and model. To power our chip design platform, we trained a language model from scratch that sets a new U.S. open-weight SOTA on agentic coding. We optimized the model architecture for our training and serving platforms, driving substantial efficiency gains. Today, we release Ripple-65B Preview, a general-purpose variant of the proprietary model that powers our AI chip design platform. The model is pr
