released today, 2025-01-17

Command-line arguments used

./sd-server --listen-ip 0.0.0.0 --listen-port 8081 --color --diffusion-model z_image_turbo-Q4_K.gguf --vae z-vae.safetensors --llm Qwen3-4B-Instruct-2507-UD-Q5_K_XL.gguf --cfg-scale 1.0 --diffusion-fa --lora-model-dir lora --upscale-model RealESRGAN_x4plus_anime_6B.pth --upscale-repeats 1 -H 240 -W 320 --steps 8;

Steps to reproduce

1. Attempt to use --upscale-model RealESRGAN_x4plus_anime_6B.pth with sd-server
2. Notice the model is not loaded in the console output
3. Generate a request and notice the resolution is not upscaled
4. Use the same argument with sd-cli and notice that the image is upscaled

What you expected to happen

I expected sd-server to upscale all requests by default when the upscale-model is included on the command line.

What actually happened

upscale-model is ignored.

Logs / error messages / stack trace

No response

Additional context / environment details

using z-image-turbo. upscaling does work in sd-cli with this model.
