+**Data Explanation**
+
++ When testing with the diffusers library, the `enable_model_cpu_offload()` and `pipe.vae.enable_tiling()` options were
+  enabled. This configuration was not tested on non-**NVIDIA A100 / H100** devices, but it should generally work on all
+  **NVIDIA Ampere architecture** and above. Disabling these optimizations will significantly increase memory usage, with
+  peak usage approximately 3 times the values shown in the table.
++ For multi-GPU inference, `enable_model_cpu_offload()` must be disabled.
++ Inference speed tests used the above memory optimization options. Without these optimizations, inference speed
+  increases by around 10%.
++ The model supports only English input. For other languages, translation to English is recommended during large model
+  processing.
