OBLITERATUS model weight modification process (EXCISE).
Technical Positioning
Ensuring robust and type-safe weight modification during the 'obliteration' process, preventing fundamental data type casting errors.
SaaS Insight & Market Implications
This issue reports a critical runtime error during OBLITERATUS's core 'EXCISE — Modifying weights' phase: 'result type Float can't be cast to the desired output type Byte.' This indicates a fundamental data type incompatibility or conversion failure within the weight modification pipeline, likely related to quantization or memory optimization. Despite using `Cuda Nightly 12.8`, the error persists, suggesting a core architectural or implementation flaw rather than a simple dependency issue. Such errors halt the 'obliteration' process entirely, rendering the tool unusable for its primary function. This represents a severe stability and reliability problem, directly impacting the product's ability to deliver its promised value in a B2B context.

I'm having the same issue. I wonder if it's a quant issue. If the model doesn't full fit in VRAM. I got models that fit to work just fine but anything that doesn't won't work.

I don't think you abliterate on quant models. I'm pretty sure you need to abliterate first then quant to nvfp4. I think it only uses 4bit for the finding the refusals.
just a convenince thing tbh
