+**New to Core AI? [Start with CoreAIKit 0.7.1](https://github.com/john-rocky/coreai-kit#readme).** Follow its requirements and first-run steps for `qwen3-0.6b`, then open the same release's [ChatDemo](https://github.com/john-rocky/coreai-kit/tree/0.7.1/Examples/ChatDemo). The README records the tested OS/SDK and download size; model and device coverage is stated per example.
