Best for

Developers trying Meta’s Muse Spark coding CLI (multi-agent by default) who will explicitly choose Contributor vs Standard pricing as a data-governance decision.

Skip if

You need BYOK multi-lab routing, refuse train-on-you Contributor terms for customer repos, or want an open-source harness you can audit (Prime Agent / OpenCode / Kilo).

  • Terminal-first engineers who live in the shell and git

Pros

Meta Superintelligence Labs terminal coding agent (beta) powered by Muse Spark 1.2 — multi-agent by default (parallel workers + background reviewers), append-only local event log for crash resume, cookbooks for worktrees/computer-use/GitHub bots; co-trained harness claims better tool use than a generic wrapper.

Cons

Contributor tier (~$0.10 in / $0.20 out) is ~12–21× cheaper than Standard because Meta trains on those prompts/completions and throttles throughput — treat as a governance choice, not just a line item; Standard (~$1.25/$4.25) keeps training off; beta + Meta Model API lock-in; not a BYOK multi-lab harness like OpenCode/Prime Agent.

Agent standards & memory

AGENTS.md: PartialSKILL.md: PartialRules / memory: Local append-only event log; multi-agent session/worktree state; Meta Model API config.Beta install (curl installer); pay Muse Spark Contributor (train-on-you, throttled) or Standard (no training on prompts/completions).
