From d389891a2516a69838b0a1fe78e9d726b45bf95f Mon Sep 17 00:00:00 2001 From: quantumaikr Date: Fri, 10 Apr 2026 20:54:46 +0900 Subject: [PATCH 1/2] feat(wasm): Llama 3.2 1B Instruct default + skip Q4 reconversion MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two changes for WASM demo reliability and speed: 1. Model: switch from Qwen3.5-0.8B (base, gated, Qwen arch issues) to Llama 3.2 1B Instruct (verified working, good quality, public HuggingFace URL, proper Instruct tuning for chat). 2. Speed: add -DTQ_NO_Q4=1 to WASM build. Skips the load-time Q4 reconversion (GGUF Q4_K_M → FP32 → internal Q4) which was expensive and redundant for already-quantized models. Uses GGUF on-the-fly dequant instead. Saves several seconds of model init and reduces peak memory usage. Added compile-time #ifdef TQ_NO_Q4 guard in quant.h so it works in WASM (no getenv). Native builds are unaffected.

charset=UTF-8 Content-Transfer-Encoding: 8bit 1B model causes 15-30s+ prefill hang in WASM — unusable as default. SmolLM2-135M: 135MB download, <2s prefill, ~10-20 tok/s in WASM. Quality is basic but responsive — proper demo experience. Llama 3.2 1B Instruct kept as "Quality" option for users willing to wait for the larger model.
