# Beholder — q4f16 (in-browser / WebLLM)

The **MLC `q4f16_1`** build of the **Beholder** state-extractor — runs **fully in the browser** on
WebGPU via [WebLLM](https://github.com/mlc-ai/web-llm), and against any OpenAI-compatible endpoint.

Beholder reads roleplay / narrative prose and emits structured character state — clothing, colors,
materials, held items, and wounds — per body slot, so a paperdoll panel can track what characters are
wearing and carrying without the roleplay model losing the thread.

The Beholder extension polls `version.json` and offers a one-click update when a newer build publishes here.

## Contents
- `params_shard_*.bin` + `tensor-cache*.json` — quantized 4-bit weights
- `Beholder-q4f16-webgpu.wasm` — compiled WebGPU model library (WebLLM `model_lib`)
- `mlc-chat-config.json` — runtime config (browser-right-sized context)
- `tokenizer.json` / `tokenizer_config.json`
- `version.json` — update manifest

## Notes
- 4-bit is the smallest, browser-friendly build (~430 MB). For higher fidelity on native runtimes,
  use the 8-bit GGUF → [GetBeholder/Beholder-GGUF](https://huggingface.co/GetBeholder/Beholder-GGUF).
- Use near-greedy decoding (low temperature) for stable structured output.
