qwen35-4b-graphrag (safetensors)

Fine-tune of Qwen/Qwen3.5-4B for graphiti-core 0.30.1 extraction prompts (graph-rag project).

Provenance of the weights (read before use):

  • model.safetensors-00001-of-00002.safetensors is the original bf16 export.
  • model.safetensors-00002-of-00002.safetensors was rebuilt on 2026-10-08 because the original upload was empty: text and MTP tensors were dequantized from carev01/qwen35-4b-graphrag-mtp-gguf (Q8_0) through the exact inverse of llama.cpp's Qwen3.5 converter (verified by a round trip against the converter: 441/441 tensors, max error 6e-8); the vision tower is copied from Qwen/Qwen3.5-4B (untouched by the fine-tune). Those tensors therefore carry Q8_0 rounding (~0.5% relative error), the same precision the GGUF was evaluated at.

Serve with vLLM; thinking off (--default-chat-template-kwargs '{"enable_thinking": false}').
