End-to-end diffusion coverage for FLUX.2-dev in online serving mode.
|
|
|
|
Coverage:
|
|
- Cache-DiT cache acceleration backend
|
|
- CPU offload
|
|
|
|
This test verifies that FLUX.2-dev can be launched with the Cache-DiT backend
|
|
and CPU offload enabled, accepts text-to-image requests through the
|
|
OpenAI-compatible API, and returns valid generated images with the requested
|
|
resolution.
|
|
|
|
assert_diffusion_response validates successful generation and the expected
|
|
image resolution.
