Finding 4: Keras 3 delivers solid speedups over Keras 2 -- even when compiling Keras 2 to XLA.
Keras 3 consistently outperformed Keras 2 across all benchmarked models. SegmentAnything inference saw a 380% boost! StableDiffusion training throughput rose by over 150%, BERT training throughput rose by over 100%.
Simply upgrading from Keras 2 to Keras 3 (even while staying on TF) will make your models run faster.
