Muse Spark Open

I want to evaluate and, if it fits, integrate a technique from recent AI research into my project.

## Technique: Muse Spark Open
Muse Spark Open: Meta Drops 816B MoE Model — 42B Active Params, 1M Context, Runs Locally on Two Mac Studios

MoE architecture: 816B total parameters, only 42B active per request (256 specialists, top-8 routing). 1M token context window enables full-corpus-in-context RAG — skip retrieval for corpora under 1M tokens, eliminating chunking errors and retrieval misses. Native multimodal (text + image + video + audio) in a single model. Runs locally on two Apple M5 Ultra Mac Studios via MLX tensor parallelism. Cloud: Groq (ultra-low latency), Together AI, OpenRouter. Fine-tunable via PyTorch. Check Muse Model License for commercial limits.

What the reference demo shows: 4-sub-tab Gradio demo — (1) Architecture: MoE routing, 1M context implications, multimodal, local inference; (2) Benchmarks: model comparison table; (3) RAG Cost Calculator: full-context vs. retrieval-RAG cost comparison; (4) Implementation Patterns: Groq API, MLX local, long-context RAG.

## My project
<Describe your stack, the problem you want to solve and where this technique would sit. Example: "Python FastAPI RAG service over 50k PDFs, Postgres + pgvector, OpenAI embeddings, p95 latency budget 800 ms.">

## What I need from you
1. Read the reference source code and explain in at most 5 bullets how the technique works and what it would change compared to my current approach.
2. Decide whether it fits my case. If it does not, say why and stop there.
3. Propose the smallest viable integration: files or modules to touch, new dependencies, configuration.
4. Implement it behind a flag or as a separate function so it can be compared side by side with what I have today.
5. Add an evaluation script that measures latency, throughput and cost per request at equal output quality, before and after, on my own data.
6. List the risks (latency, cost, failure modes) and what to monitor once it is in production.

Constraints: keep my existing stack and conventions, avoid heavy dependencies unless the gain is clear, and reference the file in the demo source whenever you reuse its logic.
