+    Wan 2.1 T2V 1.3B — text-to-video diffusion model, GGUF-quantized for the
+    stable-diffusion.cpp backend. Generates short (33-frame) 832x480 clips
+    from a text prompt. Cheapest Wan variant, suitable for CPU-offloaded
+    inference with ~10 GB of usable RAM.

+    Wan 2.1 I2V 14B 480P — image-to-video diffusion, GGUF Q4 quantization.
+    Animates a reference image into a 33-frame 480p clip. Requires more
+    RAM than the 1.3B T2V variant; CPU offload enabled by default.
