CAIR Qwen3-8B (Q4_K_M GGUF)

LoRA SFT of Qwen/Qwen3-8B on the Home-Assistant-Requests V1 dataset, merged into the base weights and quantized to GGUF Q4_K_M.

Note: this checkpoint was trained on the V1 dataset (ShareGPT format, single-turn, no tool calling). A V2 model trained on jimdilkes/cair-v2-canonical (tool calling, multilingual, recovery-pattern supervision) is in progress.
