About

BLOOM 1B1 is a smaller checkpoint in BigScience's BLOOM family, with 1.1B parameters (1,065,314,304 per its model card). It shares BLOOM's decoder-only architecture and 2,048-token sequence length, and BigScience trained it on its multilingual corpus, which the model card describes as 45 natural languages plus programming languages. It is a base model, not instruction-tuned; the matching instruction-tuned version is BLOOMZ 1B1. Weights are on Hugging Face under the BigScience RAIL License v1.0.
