Timeline (last 90 days)
On a Mac Studio (Apple M3 Ultra, 96 GB memory), in tests using mflux 0.19.1, 8-bit quantized weights, and 1600x896 resolution, ERNIE-Image Turbo averaged a score of 4.28 (out of 5) while FLUX.2 klein 4B averaged 3.07.
FLUX.2 klein 4B's median time in the test was 22 seconds, roughly 3.6 times faster than ERNIE-Image Turbo's 80 seconds.
FLUX.2 klein 4B uses the Apache-2.0 license and can be used commercially, whereas FLUX.2 klein 9B and FLUX.2 dev use the FLUX non-commercial license.
The teacher model uses FLUX.2 klein 4B, a 4-billion-parameter diffusion model, to generate stylized versions of approximately 3,000 frames of gameplay footage, covering three weather types—snow, wet ground, and night—each at three levels of intensity.
