ctransformers

Why we included this project

If you're tired of juggling separate conversion pipelines for each model architecture, ctransformers gives you a single AutoModelForCausalLM-style interface that loads GGML/GGUF files from disk or straight from the Hugging Face Hub. It runs LLaMA, Falcon, MPT, StarCoder, GPT-2, and others in pure C/C++ via GGML, so you can do lightweight inference on a laptop without pulling in a full PyTorch runtime. Streaming output, CUDA/ROCm/Metal offloading, and LangChain integration come built in where the model supports them. The experimental GPTQ path through ExLlama helps when you're squeezing quantized weights into a tight memory budget, but support varies by model family, so check the table before committing.
