The most critical patch involves the Variational Autoencoder (VAE). The original Anya Oxi had a "baked-in" VAE that was incompatible with standard EMA (Exponential Moving Average) weights. This caused magenta flashes in high-contrast images. The patched version decouples the problematic VAE, making it fully compatible with standard 840000 VAE files.
One major benefit of the patch is LoRA interoperability. The original Anya Oxi frequently clashed with detail-enhancing LoRAs (like "More Details" or "Epic Noise Offset"). The patched version fixes the tensor alignment.
Top performing LoRAs (Tested):
Warning: Do not use the "Anya Oxi Fix LoRA" created for the original model. That LoRA attempts to patch a patched model, resulting in severe over-saturation and negative prompts bleeding into positive space.
No article on the anya oxi model patched would be complete without addressing the elephant in the room. In late 2024, a malicious actor released a "fake patch" containing a string that poisoned the model’s text encoder.
Signs of a compromised model:
How to stay safe:
Even with the patched version, users encounter problems. Here is the fix guide for the three most common complaints:
Issue 1: "The patched model still looks like the old one."
Issue 2: "The colors are too grey."
Issue 3: "I get a RuntimeError: 'mat1' and 'mat2' shapes cannot be multiplied."

Step 1: Backup Your Original Model
Before replacing files, move your old anyaOxi.ckpt to a backup folder. The patched version uses a different hash; do not just rename the old file.
Step 2: Download and Place the File
Step 3: Select the Correct VAE Unlike the original, the patched model requires an external VAE.
Step 4: Recommended Settings Based on community testing (Civitai, November 2024), use these parameters for the best results:
