Qwen3-0.6B (q4f16_1, WebLLM)
Browser-ready mlc artifacts for text-generation, produced by SkillSafe's
reproducible converter (models/ in skillsafe.ai)
from a pinned upstream source. Every byte here is derivable from that source plus
the recipe below; nothing was edited by hand.

registry files are parameter files served from models.skillsafe.ai once vetted;
bundle files ship inside an app; registry-shared is a runtime library reused by
every model of the same architecture.
Verification
Shard sizes and md5s match ndarray-cache.json; the implied parameter count matches the checkpoint (751,632,384 parameters, 3.57 bits/param); the parameter table embedded in the WebGPU model library matches all 339 tensors of these weights.
Use in the browser (WebLLM)
import { CreateMLCEngine } from "@mlc-ai/web-llm";
const engine = await CreateMLCEngine("qwen3-0.6b-q4f16", {
appConfig: { model_list: [{
model: "https://huggingface.co/skillsafe-ai/qwen3-0.6b-q4f16",
model_id: "qwen3-0.6b-q4f16",
model_lib: "https://huggingface.co/skillsafe-ai/qwen3-0.6b-q4f16/resolve/main/lib/Qwen3-0.6B-q4f16_1-ctx4k_cs1k-webgpu.wasm",
overrides: { context_window_size: 4096, prefill_chunk_size: 1024 },
}] },
});
The model library is compiled for context window 4096 / prefill chunk 1024; mlc-chat-config.json says 40960 / 2048, so set the overrides above.
