Bonsai Image 4B Brings Image Generation to Local Devices
PrismML has released Bonsai Image 4B, a family of compact image-generation models that run on local devices like laptops and phones. The models use binary and ternary weight representations to shrink the diffusion transformer to under 1 GB, enabling on-device inference on iPhone 17 Pro Max and other Apple Silicon hardware. Two variants offer different trade-offs between footprint and quality, retaining up to 95% of the accuracy of the full-precision FLUX.2 Klein 4B base model.
