A user on Reddit's r/LocalLLaMA subreddit shared their experience testing new quantization methods for large language models on an RTX Pro 4500 GPU. They encountered issues with a specific Sakamakismile model, experiencing tool call errors and thinking loops. To address this, they explored PrismaQuant, a new quantization technique discussed on Nvidia's DGX Spark forum, which optimizes linear layers for better model performance at a given bit depth. The user highlighted that PrismaQuant is currently compatible with vLLM for Blackwell architecture and noted the limited support for GGUF formats. AI
