Freshness 89 out of 100. Release age: 30 days old, Oct 15, 2026. Measures age, not quality.

What do these scores mean?

Two ways to compare models. Neither score measures answer quality, benchmark performance, or whether a model fits your machine.

Freshness · release age

A new release starts at 100. The score halves every 180 days: 100 × 2^(−age in days / 180). When the release date is unavailable, a repository date is a fallback—not proof of when the model was released. Missing dates stay unscored.

Check the date source

Popularity · adoption

Downloads over the past 30 days carry 80% of the score; lifetime likes carry 20%. Both use a logarithmic scale, capped at 10 million downloads and 100,000 likes. If likes are unavailable, downloads carry all the weight. Missing download statistics stay unscored.

Best for

Create images from a prompt in ComfyUI on your own NVIDIA GPU.
Edit a photo from a written instruction with it as the reference image.

Tradeoffs

Gated download: accept the license on Hugging Face first.
The license restricts commercial use for larger organisations.
On a Mac it runs through mflux’s community 8-bit MLX conversion, not Black Forest Labs’ own files.
Edits can change areas outside the requested region.

Ways to run it

ComfyUI 0.41.0+ · Windows, Linux · NVIDIA

Official text-to-image and image-edit templates for both checkpoints.

Official instructions
