NEXS Qwen3-32B russian-refalmachine LoRA (vLLM-ready)

Rank-128 LoRA adapter (bf16) extracted with mergekit from RefalMachine/RuadaptQwen3-32B-Instruct against the base model Qwen/Qwen3-32B, then sanitized for vLLM serving.

Sanitization applied

The raw mergekit extraction included full-rank modules_to_save tensors (embed_tokens, lm_head, and norm layers) that vLLM's LoRA runtime does not support. This upload contains only the pure low-rank lora_A/lora_B weights (448 pairs: 64 layers x q/k/v/o/gate/up/down projections), with modules_to_save: null in adapter_config.json. No resize_token_embeddings() call is needed to load this adapter.
