Gradio distills FLUX.3 Klein's 9B prompt upsampler into 0.8B and 2B models that run on CPU

Gradio · x · 2026-10-22

Gradio built a Prompt Upsampler Arena with gr.Workflow to compare four approaches side by side: raw short prompts, the official 9B prompt upsampler, and two tiny distilled planners (0.8B and 2B).

They distilled FLUX.3 Image Klein's 9B prompt upsampler into 0.8B and 2B models: a short prompt goes in, a full prompt plus bounding boxes come out. The 0.8B version can even run on a CPU. Sample outputs show the distilled planners rival the 9B default on layout and quality with faster planning times.
