Compare the Muse Code Everyday, High, and Power subscription plans

What Muse Code is

Muse Code is Meta’s subscription wrapper around the Muse Spark Model API, aimed at developers who want a flat monthly rate for coding-agent usage instead of metering every token. Rather than billing per million tokens like the raw API, it bundles usage into fixed monthly plans with a pay-as-you-go fallback once a plan’s allowance is used.

The three plans

Muse Code ships three flat-rate tiers, scaled for how much agent usage a developer expects in a month.

• Everyday — $5/month: light, occasional coding-agent use
• High — $15/month: daily use across one or two active projects
• Power — $50/month: heavy, multi-project or team-adjacent usage

What happens past the plan allowance

Usage beyond a plan’s included allowance falls back to pay-as-you-go token pricing — the same underlying Muse Spark 1.3 rates published on Meta’s pricing page, billed per million tokens rather than as a flat fee. This keeps a subscriber from being hard-capped mid-task, at the cost of a less predictable bill in a heavy month.

The TypeScript SDK preview

Meta has a TypeScript SDK in preview for Muse Code, aimed at developers building their own coding-agent harnesses on top of the subscription rather than calling the raw Model API directly. As a preview, treat its interfaces as unstable until Meta publishes a stable release.

Choosing a plan

Start on Everyday if you are experimenting or use a coding agent a few times a week. Move to High once daily use becomes routine on one or two projects. Power suits teams or individuals running agent workloads continuously across multiple projects, where the flat $50 rate is likely cheaper than metered pay-as-you-go token billing at that volume — verify against your own usage before committing.
