  • I don’t follow the discussions on this topic very closely, but as I understood, there are different ways to achieve the goal, but all impact quality to some extent. Heretic is discussed as one one of the SOTA methods. The README posted above states the following, so it seems that heretic is some sort of next gen abliteration.

    It combines an advanced implementation of directional ablation, also known as “abliteration” (Arditi et al. 2024, Lai 2025 (1, 2)), with a TPE-based parameter optimizer powered by Optuna.










  • Thank you for taking the time to respond.

    I’ve used vLLM for hosting a smaller model which could fit in two of GPUs, it was very performant especially for multiple requests at the same time. The major drawback for my setup was that it only supports tensor parallelism for 2, 4, 8, etc. GPUs and data paralellism slowed inference down considerably, at least for my cards. exllamav3 is the only engine I’m aware of which support 3-way TP.

    But I’m fully with you in that vLLM seems to be the most recommended and battle-tested solution.

    I might take a look at how I can safely upgrade the driver until I can afford a fourth card and switch back to vLLM.
