Running AI models on your laptop has become much easier, and llama.cpp has been a big part of that. Its inference engine powers local AI tools such as Ollama, LM Studio, and Jan. Alongside projects like MLX, it has helped make local inference a practical option for everyday use.
This is where we are right now. And i’m not gonna lie it feels pretty magical 🧙♀️

GGUF, developed by the llama.cpp team, is a widely used format for local inference. The team also shares quantized checkpoints under ggml-org on the Hub. Publishers such as Unsloth, LM Studio Community, and bartowski also provide ready-to-use GGUF checkpoints in a range of quantizations, so users can pick the version that fits their machine. GGUF models have been downloaded millions of times.
We want to make it easier to run these models locally with transformers, too. Compatibility is only useful if the model is pleasant to run. To bring performance close to llama.cpp, we're reusing its underlying ggml kernels through the kernels library, and reducing overhead in generate. Our initial focus is local inference on Apple Silicon, starting with the Qwen3.5 architecture.
GGUF packages model weights and metadata, including tokenizer information and an optional chat template, in one file. It supports different quantization levels, letting you trade some precision for a smaller memory footprint.
