Spark-X2.6-4B boosts on-device AI coding and reasoning
What is Spark-X2.6-4B-GGUF?
Spark-X2.6-4B is a 4-billion-parameter language model built for laptop- or phone-side inference. It adds stronger coding, multi-step tool use, long-context and multilingual reasoning, with three configurable thinking levels to balance speed and quality.
Who it is for
Developers who want local AI assistants or on-device code helpers can grab the model and run it with llama.cpp for faster, higher-quality results without cloud calls.
How to try it
Download the GGUF file from Hugging Face and run it with llama.cpp (e.g. ./llama.cpp -m spark-x2.6-4b-q4_0.gguf)
