(WIP) - this will be updated with multi-chip latency and support for Flux2 Klein 9B!
Draft PR for the Flux2 Klein model. Includes a custom implementation of the Qwen3-4B model for getting text embeddings. VAE Decoder, RoPE positional embedder, flow-matching step schedule are all re-used. Light modifications to transformer/attention blocks are used.
Latency for batch-size 4 of 1024 by 1024 images (bfloat16):
