Triangle104/Crux-Qwen3_OpenThinking-4B-Q4_K_S-GGUF

This model was converted to GGUF format from prithivMLmods/Crux-Qwen3_OpenThinking-4B using llama.cpp via the ggml.ai's GGUF-my-repo space. Refer to the original model card for more details on the model.

---

Crux-Qwen3_OpenThinking-4B is fine-tuned on the Qwen3-4B architecture, optimized for advanced open thinking, mathematical reasoning, and logical problem solving. This model is trained on the traces of sk1.1, which include 1,000 entries from the Gemini thinking trajectory, combined with fine-tuning on 100k tokens of open math reasoning data. This makes it highly effective for nuanced reasoning, educational tasks, and complex problem-solving requiring clear thought processes.

Use with llama.cpp

Install llama.cpp through brew (works on Mac and Linux)

brew install llama.cpp

Invoke the llama.cpp server or the CLI.

CLI:

llama-cli --hf-repo Triangle104/Crux-Qwen3_OpenThinking-4B-Q4_K_S-GGUF --hf-file crux-qwen3_openthinking-4b-q4_k_s.gguf -p "The meaning to life and the universe is"

Server:

llama-server --hf-repo Triangle104/Crux-Qwen3_OpenThinking-4B-Q4_K_S-GGUF --hf-file crux-qwen3_openthinking-4b-q4_k_s.gguf -c 2048

Note: You can also use this checkpoint directly through the usage steps listed in the Llama.cpp repo as well.

Step 1: Clone llama.cpp from GitHub.

git clone https://github.com/ggerganov/llama.cpp

Step 2: Move into the llama.cpp folder and build it with LLAMA_CURL=1 flag along with other hardware-specific flags (for ex: LLAMA_CUDA=1 for Nvidia GPUs on Linux).

cd llama.cpp && LLAMA_CURL=1 make

Step 3: Run inference through the main binary.

./llama-cli --hf-repo Triangle104/Crux-Qwen3_OpenThinking-4B-Q4_K_S-GGUF --hf-file crux-qwen3_openthinking-4b-q4_k_s.gguf -p "The meaning to life and the universe is"

or

./llama-server --hf-repo Triangle104/Crux-Qwen3_OpenThinking-4B-Q4_K_S-GGUF --hf-file crux-qwen3_openthinking-4b-q4_k_s.gguf -c 2048
