Shanghai Chuangzhi Institute and Xinxiu Intelligence Release Pre-trained RSI Model 801-30B and Technical Report

Shanghai Chuangzhi Institute and Xinxiu Intelligence jointly released the first public technical report on pre-training-level Recursive Self-Improvement (RSI), open-sourcing the 801-30B base model and lightweight SFT data. The framework decomposes the irreversible pre-training macro-loop into three closeable micro-loops: debugging, potential, and empirical quantification, leveraging multi-agent systems to detect anomalies across hyperparameters, code, and data pipelines. Across 13 foundational capability benchmarks, the 801-30B base model averaged a score of 73.13 and demonstrated strong coding and agent benchmark performance following lightweight fine-tuning.
