Qwen3.5-4B Megamix: 8x Multi-Distill Merge

This model, developed by xtools-at, is a 4.5 billion parameter language model built upon the Qwen3.5-4B architecture. It represents a linear weighted merge of three distinct Qwen3.5-4B-based checkpoints: xtools-at/Qwen3.5-4B-Claude-3xMerge-Jackrong, xtools-at/Qwen3.5-4B-Heretic-2xMerge-DavidAU, and xtools-at/Qwen3.5-4B-MultiDistill-3xMerge. The primary goal of this merge is to combine diverse strengths, including reasoning distillation, Claude-derived training data, and a Heretic-derived variant, into a single model while preserving the underlying Qwen3.5-4B's general text-generation capabilities and a 32768 token context length.
