FLUX.1-lite-8B-alpha (Freepik) is architecturally identical to FLUX.1-dev with 8 double-stream blocks instead of 19. NxDI's FLUX.1 implementation reads num_layers from config.json at runtime, so it works out of the box with FLUX.1-lite weights -- no custom modeling code needed. Validated on trn2.3xlarge (LNC=2, TP=4): - 5.91s per 1024x1024 image (25 steps) - 4.49 backbone fwd/sec - ~128s compilation time - SDK 2.29, NxD Inference 0.9

There was a problem hiding this comment.
this __init__.py is just 3 comment lines with no actual imports/exports. Since there's no custom modeling code just a generation script, this is technically fine, but for future, we should be exporting the generation function for programmatic use: from .generate_flux_lite import run_generate.

The description reports 5.91s average generation time, but the test threshold is 15s. we should tighen to 10s to catch performance regressions earlier.
