Muse Spark Anywhere

Use Meta's Muse Spark (the model behind the muse CLI / Meta Model API) in
pi, Agent Orchestrator, opencode, and any OpenAI-compatible tool —
with full reasoning-effort control and no secrets in your configs.

Muse Spark speaks an OpenAI-compatible API (https://api.meta.ai/v1), but two
things trip up most tools:

1. Streaming quirk — it injects a non-standard SSE event
   (event: response.subscription_usage) that strict OpenAI parsers reject.
2. Discovery gaps — it isn't in models.dev, so tools
   that generate their catalog from there (pi, opencode, Kilo Code) don't list
   it, and some UIs (Agent Orchestrator) hardcode an older model list.

This repo collects small, focused fixes for each.

What's here

Path	What it does
pi/	Drop-in ~/.pi/agent/models.json + a Keychain key reader. Muse Spark in pi today, with minimal…max thinking levels. pi handles the streaming quirk natively.
proxy/	A ~120-line, dependency-free Node proxy that strips the non-standard SSE event, so opencode / any OpenAI GUI works. Point them at http://127.0.0.1:8788/v1.
agent-orchestrator/	A patch adding muse-spark-1.3 (+ contributor) to Agent Orchestrator's muse model catalog.
pi-provider/	Draft for an upstream pi PR: a built-in meta provider (mirrors the existing openai-compatible providers).

The clean, ecosystem-wide fix

Because pi, opencode, and Kilo Code all build their catalogs from models.dev,
the highest-leverage contribution is adding a Meta provider + Muse Spark
models (with reasoning options) to models.dev. Then every one of those tools
gets Muse Spark natively. The pi-provider/ draft is the pi-side wiring that
pairs with it.

Auth & safety

No key material is stored in any file here. The pi config and the proxy read the
key from the macOS Keychain (service ai.meta.dev.credentials, written by the
muse CLI) at request time. If you don't use the muse CLI, set META_API_KEY
in your environment instead. This is developer tooling for your own Meta
Model API access — mind Meta's terms for how your plan/key may be used.

Quick start (pi)

cp pi/models.json ~/.pi/agent/models.json
cp pi/meta-key.sh ~/.pi/agent/meta-key.sh && chmod +x ~/.
