MongoDB - Build AI That Scales
Mini toolsHRM Text 1B
HRM-Text-1B is a 1B-parameter language model checkpoint from Sapient Intelligence, trained from scratch on structured public datasets and released under Apache 2.0. It uses the Hierarchical Reasoning Model architecture, a dual-timescale recurrent design with high-level and low-level Transformer modules. The model is for text generation, reasoning experiments, and NLP research, but it is not a finished chat assistant: the page states it is pre-alignment, non-chat, non-instruction-tuned, not RLHF-trained, and intended as a starting checkpoint for further alignment or task-specific training. It has a 4,096-token max sequence length, was trained on 40B unique tokens, and is primarily English.

Overview
HRM-Text-1B is Sapient Intelligence’s open-source 1B-parameter text-generation language model built on the Hierarchical Reasoning Model architecture.
About Sapient Intelligence
Sapient Intelligence is building self-evolving machine intelligence with brain-inspired hierarchical architectures designed to solve complex long-horizon reasoning tasks. The company has developed the Hierarchical Reasoning Model (HRM), an AI architecture that aims to overcome the structural limitations of traditional transformer-based systems.
