+### Default Model
+
+The setup wizard downloads **Qwen2.5-7B-Instruct** (Q4_K_M quantization, ~4.6 GB) as the default inference model.
+
+Why this model:
+
+- **Fits in 6 GB VRAM** — runs on mid-range GPUs (RX 6600 XT, RTX 3060, etc.) without offloading
+- **Instruction-tuned** — handles chat, code, and reasoning without fine-tuning
+- **Q4_K_M quantization** — best balance of quality and speed for consumer hardware; loses less than 1% accuracy vs. FP16 while fitting in half the VRAM
+- **GGUF format** — runs natively in llama.cpp (the worker backend) with no conversion step
+
+Swap it for any `.gguf` model you prefer. cAIc's query-routing works with whatever you put in `./models/` — the coordinator doesn't care which model runs where, as long as the workers can serve it.
