	# OSCAR2 Models

	Collection: [OSCAR2 Models](https://huggingface.co/collections/jabbatheduck/oscar2-models-6a6004563e2dbe1dedd28750)

	## Model

	\| Name \| File \| KV cache \| Context \|
	\|------\|------\|----------\|---------\|
	\| Qwen3.6-27B-Q5KXL-Hadamard \| `qwen3.6-27b-q5kxl-hadamard.gguf` \| oscar2/oscar2 \| 131072 \|

	## OSCAR2 Source

	This model requires an oscar2-capable build of `llama.cpp` from the TurboQuant oscar branch.

	- Repo: https://github.com/giveen/llama-cpp-turboquant
	- Branch: `oscar`

	## Build Instructions

	```bash
	git clone -b oscar https://github.com/giveen/llama-cpp-turboquant.git
	cd llama-cpp-turboquant
	mkdir build && cd build
	cmake .. -DCMAKE_BUILD_TYPE=Release -DGGML_CUDA=ON
	cmake --build . --config Release -j $(nproc)
	```

	## Run with this Model

	```bash
	./build/bin/llama-cli \
	-m /path/to/qwen3.6-27b-q5kxl-hadamard.gguf \
	-ngl 99 -fa on -c 131072 \
	--cache-type-k oscar2 --cache-type-v oscar2 \
	-n 512 --temp 0
	```

	## Notes

	- Requires NVIDIA Blackwell GPU with CUDA 13.3 or compatible.
	- KV cache stores ~2.25 bits/weight with oscar2 quantization.
	- Use `--no-jinja` if chat template parsing fails with very long prompts.
