Introducing 1-bit and Ternary Bonsai Image 4B: Image Generation for Local Devices (9 minute read)

Bonsai Image 4B is a family of compact image-generation models that can run high-quality diffusion inference on local hardware. The 1-bit variant is for applications where memory pressure, bandwidth, and deployment footprint are the primary restraints. The ternary variant has representational flexibility, giving it improved visual quality and prompt fidelity while remaining extremely compact. The models can run directly on an iPhone.
