Thanatos-27B examples

Four minimal entry points. Pick the one that matches how you run models.

File	Backend	When to use
`ollama_chat.py`	Ollama HTTP API	You already have `ollama serve` running and the `thanatos-27b` model created from the project `Modelfile`. Text + tool calling — vision via Ollama is broken upstream for this arch.
`transformers_quickstart.py`	Hugging Face Transformers	You want to run the upstream safetensors (`Qwen/Qwen3.6-27B`) on GPU, optionally in 4-bit via bitsandbytes.
`llama_cpp_quickstart.py`	llama-cpp-python	You want to invoke a local GGUF directly without a daemon (CI, batch jobs, scripts). Text only.
`llama_cpp_vision.py`	llama-cpp-python + mmproj	Image input. Loads a text GGUF + `mmproj-F16.gguf` and answers questions about an image. The only working vision path right now.

All four apply the same Thanatos system prompt and sampling defaults (temp=0.6, top_p=0.95, top_k=20, repeat_penalty=1.05) so behavior should be consistent across backends modulo quantization noise. The three non-Ollama scripts set them explicitly; ollama_chat.py inherits them from the Modelfile / bridge files.

Setup

Ollama

Pull straight from HF (gets the bundled Q4_K_M GGUF + this repo's root-level template / system / params files via HF's Ollama bridge):

ollama pull hf.co/FoolDev/Thanatos-27B           # 17 GB Q4_K_M (only bundled quant)
pip install requests
MODEL=hf.co/FoolDev/Thanatos-27B python ollama_chat.py

If you pulled before the latest qwen35 re-stamp (HF commit e03e10e) and still have a qwen36-stamped blob in your local Ollama store, run cd .. && make heal-hf once to rebadge it in place (qwen36 → qwen35, metadata-only, ~5 s) — the same tag then loads. Fresh pulls after the re-stamp go straight through.

For a non-bundled quant (e.g. Q3_K_S ~12 GB, Q5_K_M ~20 GB), make build QUANT=... downloads from unsloth/Qwen3.6-27B-GGUF and creates a local thanatos-27b tag:

cd ..  &&  make build QUANT=Q3_K_S  &&  cd examples
MODEL=thanatos-27b python ollama_chat.py

Or build a local tag from this repo's bundled GGUF without going through the HF pull:

cd ..  &&  make load-bundle  &&  cd examples
MODEL=thanatos-27b python ollama_chat.py

For a quant the repo doesn't bundle (e.g. Q5_K_M), make build will fetch it from unsloth/Qwen3.6-27B-GGUF and patch the Modelfile FROM line into a temp copy automatically:

cd ..  &&  make build QUANT=Q5_K_M  &&  cd examples
python ollama_chat.py

Transformers (safetensors)

pip install --upgrade "transformers>=4.45" accelerate sentencepiece bitsandbytes
python transformers_quickstart.py            # 4-bit, ~16 GB VRAM
python transformers_quickstart.py --no-4bit  # bf16, ~54 GB VRAM

llama-cpp-python (GGUF, no daemon)

pip install llama-cpp-python  # CPU-only build
python llama_cpp_quickstart.py /path/to/Qwen3.6-27B-Q4_K_M.gguf --gpu-layers 99

For GPU offload, rebuild llama-cpp-python with the matching backend — see the script header for CMAKE_ARGS recipes (CUDA, Metal, ROCm/HIP).

Vision (image input)

# Pull the projector once (~927 MB):
hf download unsloth/Qwen3.6-27B-GGUF mmproj-F16.gguf --local-dir .

pip install llama-cpp-python pillow
python llama_cpp_vision.py \
  --gguf /path/to/Qwen3.6-27B-Q4_K_M.gguf \
  --mmproj /path/to/mmproj-F16.gguf \
  --image /path/to/photo.jpg \
  --prompt "Describe this image."

Why not Ollama? Ollama's Go engine has the qwen35 / qwen35moe arch entries (text inference works in 0.24+), but the C++ llama.cpp fallback that Ollama switches to when an mmproj is attached still lacks them. ollama create accepts the dual-FROM and ollama show reports vision capability, but the first inference call fails with error loading model architecture: unknown model architecture: 'qwen35' (verified empirically against the dense 27B + mmproj-F16.gguf). Tracked in ollama/ollama#15898. Until that's fixed, llama.cpp / llama-cpp-python is the working path for vision.
