Booper-Big
Booper-Big is a from-scratch English MoE language model trained on the English split of
openbmb/Ultra-FineWeb. It uses the standard Hugging Face Mixtral implementation.

The training stream filtered the already-curated English split to quality score ≥0.70 and held the last prepared shard out of training. The model was trained with 1,024-token packed sequences; RoPE and the published configuration support a 4,096-token context window.
