AI coding tool cost calculator

Tell it how you work. It estimates what each tool would cost you per month and picks the cheapest option that fits.

ToolBest option for youEst. per monthNote
How the estimate works

Tasks per month = tasks per day x days per week x 4.33. For pay-per-token tiers we assume each task reads the token volume below for your codebase size, with 60% of input served from cache. For subscriptions we pick the cheapest plan whose usage allowance we estimate covers your task count. Plan allowances are our editorial estimates, not vendor numbers. Treat the result as a guide.

  • Small (< 10k lines): ~60k input + ~6k output tokens per task
  • Medium (10k-100k lines): ~150k input + ~12k output tokens per task
  • Large / monorepo (> 100k lines): ~400k input + ~25k output tokens per task

What is Muse Code?

Muse Code is a command-line coding agent built by Meta Superintelligence Labs. You give it a task in your terminal; it can hand parts of the work to parallel subagents, runs shell commands in a sandbox with approvals, and records every session as an event log you can resume or rewind. Its newest model is Muse Spark 1.3.

Muse Code pricing and plans at a glance

Three monthly plans (Everyday, High, Power), or pay per token. Full details, token rates and the Contributor trade-off are on the Muse Code pricing page.

PlanPriceUsage
Everyday Usage$5/mo10-50 prompts every 5 hours, incl. image and video uploads; voice mode; web search
High Usage$15/mo5x the Everyday Usage plan; more multimodal inputs
Power Usage$50/mo20x the Everyday Usage plan; multi-agent by default; early access; higher file uploads

Is Muse Code free?

No. The CLI is free to install, but every session is billed, either against a plan or per token. The cheapest way in is the $5 Everyday plan. The cheapest per-token tier (Contributor) is very low cost because you allow your sessions to be used for training future Meta models.

Which plan fits your usage?

Light use (a few tasks a day on a small project) usually fits Everyday. Daily work on a real codebase points to High. Power is priced for teams or all-day agent runs. If your employer forbids training on its code, avoid the Contributor token tier and check Meta's terms for the plan you pick. Run the calculator with your own numbers.

How to install Muse Code

One command installs it on macOS and Linux (curl -fsSL https://dev.meta.ai/install.sh | sh) or Windows PowerShell (irm https://dev.meta.ai/install.ps1 | iex). Our step-by-step guide covers sign-in, the trust prompt, commands and your first task.

Don't confuse it with Meta Muse

Meta Muse is the consumer AI assistant at muse.ai (US only for now; free, with $20 and $100 monthly plans). It is not Muse Code. If you want an AI that writes and edits code in your repository, you want Muse Code.

FAQ

What is Muse Code?

Muse Code is a terminal-based AI coding agent from Meta Superintelligence Labs. It can split work across parallel subagents (optionally each in its own git worktree), runs shell commands in a sandbox, and runs on Meta's Muse Spark models, the newest being Muse Spark 1.3.

Is Muse Code free?

Installing it is free, but using it is not. Meta lists no free usage tier: you either pay per token or pick a monthly plan (Everyday at $5, High at $15 or Power at $50).

Is it Muse Code or Muse AI Code?

Same product. The official name is Muse Code; many people search for it as "Muse AI Code" because it comes from Meta's Muse AI family.

Is Muse Code the same as Meta Muse?

No. Meta Muse is the consumer AI assistant at muse.ai (US only for now; free, with $20 and $100 monthly plans). It is not Muse Code.

Does Muse Code work on Windows?

Yes. It runs natively on Windows (installed from PowerShell), as well as on macOS and Linux. Voice input and session messaging are not available on Windows.

Is there a Muse Code desktop app or VS Code extension?

The official docs describe a command-line tool only, with no IDE extension. Run it in VS Code's integrated terminal, and only install from dev.meta.ai.

Is my code used for training?

It depends on how you pay. The Contributor token tier ($0.1 per 1M input tokens) is discounted because you allow Meta to train future models on your prompts and completions. The Standard tier ($1.25 per 1M input tokens) is regular pricing without that permission.

Should I use Muse Code or Claude Code?

Claude Code is the more proven choice today: on Meta's own launch benchmark charts, Muse Spark 1.2 scored below Claude Opus 5 (the model behind Claude Code) on every coding benchmark shown, for example 82.9 vs 86.7 on Terminal-Bench 2.1. Muse Code is cheaper to start with and has strong multi-agent tooling. See our full Muse Code vs Claude Code comparison for which fits your work.
