fal announced a 6x speedup in serving Ideogram V4, reducing 1K resolution generation time from 2.75 s to 0.44 s without visible quality loss. The optimization was achieved by running the diffusion transformer in FP4 on Blackwell hardware, fusing small operations into GEMM kernels, and distilling classifier-free guidance and denoising steps.

## Evidence

Verbatim from https://blog.fal.ai/serving-sub-second-ideogram-v4-without-quality-loss/:

> At @fal we serve Ideogram V4 at high speed. At 1K resolution, a generation that used to take 2.75 s now renders in 0.44 s, a 6x speedup with no visible quality loss.
