📦 Downloads

🎯 Q4_K_M is recommended for most users — good quality with 16 GB VRAM usage.

📷 Multimodal Projector (mmproj)

For vision support, pair this model with the mmproj from Qwen/Qwen3.6-27B:

# Extract mmproj from Qwen3.6-27B vision model
python3 ./llama.cpp/convert_hf_to_gguf.py \
  --mmproj Qwen/Qwen3.6-27B \
  --outfile mmproj-qwen3.6-27b.gguf

# Use with llama-server for vision + tool calling
./llama-server \
  -m qwen27b-agent-R2-preview.Q4_K_M.gguf \
  --mmproj mmproj-qwen3.6-27b.gguf

Training Details

Each LoRA was trained independently via SFT on specialized datasets. Then all 4 were fused into the base model at their respective scales. The low scales (0.15-0.4) ensure no single LoRA overpowers the model — creating a balanced agent.

MTP Tensor Injection

The Multi-Token Prediction head (15 tensors) was injected from huihui-ai/Huihui-Qwen3.6-27B-abliterated to enable speculative decoding:

# MTP head adds blk.64.* tensors for draft-2-token prediction
--spec-type draft-mtp  # Enables in llama.cpp
--spec-draft-n-max 2   # Max draft tokens

---

⚡ MTP Speculative Decoding

Multi-Token Prediction enables speculative decoding:

Standard:  [token₁] → [token₂] → [token₃] → ...  (~36 TPS)
MTP:       [token₁ token₂] → [token₃ token₄] → ...  (~66 TPS)

• MTP head adds ~849 MB to model size
• Uses --spec-type draft-mtp in llama.cpp
• Best for single-user agent workloads
• ~1.2–1.8× decode speedup
