A user on Reddit's r/LocalLLaMA shared findings comparing the performance of the Qwen3.8 27b model using INT8 quantization versus INT4 Activation Aware Quantization (AWQ). The user observed a significant increase in looping behavior and a decrease in per-task success rate when using INT4 AWQ, particularly at longer context lengths exceeding 100k tokens. While INT8 also exhibited looping, the INT4 quantization exacerbated the issue, suggesting that context length and pushing the model too hard are primary drivers of these loops. AI
IMPACT Quantization choices significantly impact model stability and performance, especially at scale, requiring careful consideration for long-context applications.
