Ripple-65B Preview: U.S. Open-Weight SOTA on Agentic Coding

By · Published by Everything Blog

In short

Ricursive Intelligence developed the 80-layer dense Transformer model from scratch for an estimated $32 million, roughly one-tenth the cost of the prior benchmark leader. Pretrained on 12 trillion tokens with support for up to a 1-million-token context length, it achieved an 80.52 score on TerminalBench 2.1. The system attained this benchmark through 1.4 million reinforcement learning rollouts rather than external posttraining data. The weights are currently accessible across platforms like Hugging Face, Together AI, GMI Cloud, and OpenRouter.

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 pretrained on 12 trillion tokens with support for up to 1M context length. Ripple-65B Preview delivers strong results on agentic coding, achieving U.S. open-weight state-of-the-art (80.52) on TerminalBench 2.1 and surpassing significantly larger US open-weight models such as Reflection Beam 501B (80.1), Meta Muse Spark Open 816B (76.4), Thinking Machines Inkling 975B (63.8), and NVIDIA Nemotron 3 Ultra 550B (56.4).

Ripple’s dense model architecture provides strong reasoning performance with low-latency token generation. The model’s small parameter envelope also enables it to run efficiently on local devices such as NVIDIA DGX Spark, which feature high compute FLOPs…
