Ostris AI Toolkit Lora Training Issue: Unexpected Character Emergence
Check Ostris AI toolkit for shared latent memory across lora trainings.
Check Ostris AI toolkit for shared latent memory across lora trainings.
Summary
A user trained a character lora on a clothing style using the Ostris AI toolkit and observed that after about 2000 training steps a previously trained lora’s character appeared in the new model. The base model had no memory of the earlier lora, and none of the training images were similar to the earlier work.
The incident suggests a possible shared latent memory or model leakage within the Ostris AI toolkit, raising questions about how the toolkit isolates training sessions. The user’s experience highlights a potential flaw that could affect other users performing sequential lora trainings.
Investigating the toolkit’s memory handling and training isolation is recommended to prevent unintended cross‑contamination of lora models.
Key changes
- User trained a lora on clothing style with Ostris AI toolkit
- After ~2000 steps a previous lora’s character emerged
- Base model had no memory of earlier lora
- Training images were unrelated
- Issue suggests shared latent memory or model leakage
