What is Bonsai Image?

The Bonsai Image Ternary 4B MLX 2-bit is a specialized text-to-image diffusion transformer optimized for Apple Silicon, prioritizing high-quality output in its Bonsai Image iteration. By leveraging ternary weights of {−1, 0, +1} alongside FP16 group-wise scaling within its transformer architecture, which includes Q/K/V projections, output projections, and MLP weights, it achieves notable efficiency. This model successfully compresses the FLUX.2 Klein 4B transformer from a hefty 7.75 GB FP16 down to a mere 1.21 GB, resulting in an impressive 6.4× reduction in size while still preserving visual quality and prompt fidelity similar to the original version. The deployment package tailored for Apple Silicon weighs in at 3.88 GB, encompassing the MLX 2-bit diffusion transformer, a 4-bit Qwen3-4B text encoder, and an FP16 Flux2 VAE. Once the text encoder processes the prompt encoding, it is offloaded, ensuring that only the compact transformer and VAE are retained in memory throughout the denoising loop. Additionally, this model incorporates a 4-step FlowMatchEuler sampler with guidance set at 1.0 and a shift of 3.0, effectively eliminating the requirement for CFG and negative prompts, which simplifies the generation process and enhances the overall user experience. Overall, this development marks a noteworthy leap forward in the quest for efficient and high-quality image generation technology, making it accessible for a broader range of applications. Furthermore, the advancements made in this model illustrate the ongoing evolution in the field of machine learning and image synthesis.
