About

Bonsai Image Ternary 4B MLX 2-bit is a ternary-weight text-to-image diffusion transformer deployment for Apple Silicon. It is built as a quality-oriented Bonsai Image variant, using ternary {−1, 0, +1} transformer weights with FP16 group-wise scaling in the matrix-heavy transformer layers, including Q/K/V projections, output projections, and MLP weights. The model reduces the FLUX.2 Klein 4B transformer from 7.75 GB FP16 to a 1.21 GB Bonsai Image transformer, a 6.4× smaller footprint, while keeping visual quality and prompt fidelity close to the original model. The Apple Silicon deployment payload is 3.88 GB, including the MLX 2-bit diffusion transformer, a 4-bit Qwen3-4B text encoder, and an FP16 Flux2 VAE. After prompt encoding, the text encoder is offloaded, so the denoising loop only keeps the compact transformer and VAE resident. The model uses a 4-step FlowMatchEuler sampler with guidance 1.0 and shift 3.0, with no CFG and no negative prompts required.

About

Seedream 4.5 is ByteDance’s latest AI-powered image-creation model that merges text-to-image synthesis and image editing into a single, unified architecture, producing high-fidelity visuals with remarkable consistency, detail, and flexibility. It significantly upgrades prior versions by more accurately identifying the main subject during multi-image editing, strictly preserving reference-image details (such as facial features, lighting, color tone, and proportions), and greatly enhancing its ability to render typography and dense or small text legibly. It handles both creation from prompts and editing of existing images: you can supply a reference image (or multiple), describe changes in natural language, such as “only keep the character in the green outline and delete other elements,” alter materials, change lighting or background, adjust layout and typography, and receive a polished result that retains visual coherence and realism.
