Standard Gemma models often incorporate safety alignment that "sanitizes" or weakens specific concepts within prompt embeddings. Even when the model doesn't explicitly refuse a request, this internal filtering can dilute creative intent. For LTX-2 video generation, using a standard encoder often results in:
- Reduced Prompt Adherence: Key stylistic or descriptive terms may be ignored or weakened.
- Visual Softening: Visual intensity and fine details are often "muted" to fit generic safety profiles.
- Concept Dilution: Complex or niche creative requests are subtly altered, leading to less faithful representations of your vision.
Abliteration bypasses these restrictive alignment layers, allowing the encoder to translate your prompts into embeddings with maximum fidelity. This ensures LTX-2 receives the most accurate and un-filtered instructions possible.
