I'm doing some initial testing of WaveSpeed with "First Block Cache and Compilation" which is supposed to speed up Flux, LTXV or Hunyuan generations a lot, but I'm not sure how it works or how it affects the quality yet...

Also it's rather finicky when it comes to settings, so I think this might need some deeper investigations.

Anyway... initially it can look something like this...

Generation with flux1[dev] and default dtype. 1024x1024 and a batch size of 5 on my 3090...

Without WaveSpeed:

28/28 [03:38<00:00, 7.80s/it]

Prompt executed in 223.85 seconds

With WaveSpeed (1'st generation and caching):

28/28 [03:32<00:00, 7.60s/it]

Prompt executed in 214.94 seconds

With WaveSpeed (2'nd generation, same prompt, but new seed):

28/28 [01:36<00:00, 3.44s/it]

Prompt executed in 98.44 seconds 🤔

That's a huge speedup for consecutive generations which might be interesting if you need to generate a lot of iterations of the same image...

To be continued...
