A new open-source framework called OpenBonsai has been developed to compress large BF16 language models into significantly smaller ternary GGUF files, reducing model sizes to approximately 2 GB. This framework utilizes techniques like signed Hadamard rotations, sequential GPTQ, and self-generated reasoning traces for calibration, achieving substantial size reduction for models like Qwen3.5-9B. While the compression process takes around 5 hours on a high-end GPU, it enables more local deployment of AI capabilities, though current performance metrics show a slight decrease compared to original models and Prism's official ternary models.
