Bonsai 1 Bit Announcement: https://prismml.com/news/bonsai-8b Hugging Face: https://huggingface.co/prism-ml/Bonsai-8B-mlx-1bit Bonsai 1 Bit is a 1 bit language model that comes in 8B, 4B, and 1.7B parameter sizes. The 8B model is 1/16 the size of comparable 16 bit 8B open models with similar performance. At 1.15gb, this model can fit on many kinds of devices with 4-5x better energy efficiency
