Kolosal AI is an open-source platform built to train, run, and interact with LLMs directly on your own device. At just 20 MB in size, it’s ultra-lightweight yet optimized for speed, delivering inference as fast—or faster—than bulkier competitors like Ollama or LMStudio. By keeping everything local, Kolosal ensures complete privacy while drastically reducing energy consumption, making it one of the most sustainable ways to work with AI.


Designed to fit seamlessly into any workflow, Kolosal can be installed in minutes and supports both CPUs and GPUs out of the box. Whether you’re chatting in the CLI, switching models through its library, or embedding LLMs into apps, the experience stays fast, smooth, and flexible. Its modular runtime is optimized for low memory use, making it efficient on desktops today—and soon even on smartphones and single-board computers like Raspberry Pi or Jetson.


For developers and enterprises, Kolosal also provides API access, quantization support, and integration hooks to build secure, local AI solutions. From private experiments to production deployments, Kolosal makes advanced language models accessible, eco-friendly, and fully under your control.
