Mage is a family of lightweight, research-friendly multimodal models built at a fixed 4B-parameter budget. It is designed to make advanced visual understanding and generation accessible for controlled experiments, post-training research, and vertical-domain applications under realistic compute budgets.

The family is organized around a shared codec-aligned efficiency philosophy — spend representation capacity where the signal is — applied to both the understanding and the generation side:

Both models are compact enough to train, fine-tune, and deploy on modest hardware, yet remain competitive with much larger open systems in their respective domains.

Mage-VL is a codec-native, proactive-streaming multimodal foundation model for image & video understanding, trained entirely from scratch at a compact 4B scale.

Coming soon — code, checkpoints, and full details are on the way. Stay tuned.

Mage-Flow is a compact 4B generative stack for text-to-image generation and instruction-based image editing, built from two co-designed components: Mage-VAE (a lightweight, high-fidelity latent tokenizer) and a Native-Resolution Multimodal Diffusion Transformer trained with rectified flow matching. Each task ships in Base, RL-aligned, and 4-step Turbo variants.

Highlights

• Compact & competitive. A single 4B family for generation and editing that matches or beats much larger open systems (Qwen-Image 20B, Z-Image 6B, FLUX.2 32B, FireRed-Image-Edit 20B).
• Efficient tokenizer. Mage-VAE matches FLUX.2-VAE reconstruction fidelity using ~12× / ~22× fewer encode / decode MACs per pixel, removing the VAE high-resolution bottleneck.
• Native resolution. One checkpoint generates from 512 to 2048 on any aspect ratio, including extreme 4:1 (e.g. 512×2048, 2048×512).
• System-level speed. Native-resolution packing + fused CUDA kernels cut per-step training time from ~1.93 s → ~0.78 s (~2.5× faster training); at 1024² on a single A100, Mage-Flow-Turbo 0.59 s/image and Mage-Flow-Edit-Turbo 1.02 s/edit.
• Versatile editing. Mage-Flow-Edit supports semantic content editing, appearance transformation, image restoration, and structure-aware outputs within a unified image-and-text-conditioned model.

• 2026-07-22 — Mage-Flow checkpoints released on Hugging Face: Base, RL-aligned, and 4-step Turbo variants for both text-to-image generation and image editing.
• Coming soon — Mage-VL: a Base vision–language model plus a proactive-streaming variant for codec-native image & video understanding. Stay tuned.

Mage-VL — vision–language (image & video understanding).

Mage-Flow — generation & editing. Each checkpoint is a self-contained diffusers-style repo (transformer/ + shared vae/, text_encoder/, scheduler/).

Each model is self-contained in its own directory with a dedicated README:

• Mage-VL — image/video understanding demo, codec backends, CLI → mage_vl/README.md
• Mage-Flow — installation, Python API, CLI, prompt enhancement, Gradio app → mage_flow/README.md

These models are released for research purposes only and are not intended for product or service deployment. Responsible AI considerations were incorporated throughout the development process, including data selection, model training, and evaluation. The training data includes a combination of public, licensed, and internal datasets that were processed to remove clearly identifiable personal information and reduce harmful content where possible. However, as the data is largely sourced from web-scale collections, it may contain biases or uneven representation. As a result, the models may generate outputs that are inaccurate, biased, or inappropriate under certain prompts. The models should be used in controlled research settings with appropriate human oversight, and downstream users are responsible for applying additional safeguards — such as content moderation, validation, and compliance checks — before broader use.
