🤖 Local LLM Architecture & Quantized Model Composition

When deploying edge AI or running local GGUF models in-browser (via WebGPU / WASM ONNX) or locally via Ollama / LM Studio, prompt formatting must match the exact token delimiters of your model weights:

  • SmolLM-135M-Instruct: ~90 MB download · Q4_K_M 4-bit quantized · Ideal for ultra-fast in-browser micro-chat (50+ tok/s)
  • Qwen2.5-0.5B-Instruct: ~290 MB download · Q4_K_M 4-bit quantized · Exceptional multi-turn logic & code generation
  • Llama-3.2-1B / 3B: ~1.1 GB download · Q4_K_M 4-bit quantized · Standard Llama-3 special header tokens
