Muse Code vs Claude Code: Benchmarks, Price and Workflow

Muse Code vs Claude Code is the first comparison most developers run, because Muse Code is Meta's cheapest per-token route into agentic coding and Claude Code is the terminal agent everyone measures against.

Muse Code vs Claude Code: the quick verdict

Muse Code vs Claude Code splits on billing and platform support, not on which agent is smarter.

Pick Muse Code if you live in a macOS or Linux terminal, want per-token billing with no monthly commitment, and your usage is light or bursty. Pick Claude Code if you need native Windows, a desktop app, documented hooks and MCP, enterprise controls or a flat bill. On Meta's own reported numbers, relayed second-hand by press, Muse Code trails Claude Opus 5 on Terminal-Bench 2.1 by 3.8 points — small enough that Muse Code vs Claude Code is a price-and-platform decision, not a capability shootout.

Choose Muse Code when

  • Your workload is bursty — check volumes in the Muse Code cost calculator.
  • Contributor at $0.10 / $0.20 per M suits you, data terms accepted.
  • You need the 1M-token multimodal context of Muse Spark 1.2.

Choose Claude Code when

  • You are on Windows — see Muse Code on Windows.
  • Finance wants a predictable line item, not an uncapped meter.
  • You need documented extension points and enterprise administration.

Benchmarks: two measurement regimes, not one scoreboard

Meta's figures and Artificial Analysis's independent runs disagree; mixing them misleads.

Meta's self-reported figures (second-hand)

Meta reported Muse Spark 1.2, the model inside Muse Code, at 82.9% on Terminal-Bench 2.1 against Claude Opus 5 at 86.7%, and 59.3 on DeepSWE against Opus 5's 65.0. We have not seen these in a first-party table we can quote; they reach us via press coverage of Meta's Muse Code announcement: vendor-reported and second-hand.

Artificial Analysis's independent numbers

Artificial Analysis measured Muse Spark 1.2 at 80% on Terminal-Bench v2.1, up from 78% for 1.1, with an Intelligence Index of 54 against 51 and roughly 165 output tokens per second. SciCode and HLE regressed slightly.

Why you cannot subtract one regime from the other

Those figures describe nominally the same benchmark yet differ by three points, because harness, scaffold and sampling differ. We have no independent Opus 5 Terminal-Bench score from the same regime, so the honest reading is that Muse Code sits in the frontier band, just below Opus 5 on Meta's numbers. Detail: Muse Spark 1.2.

Muse Code vs Claude Code pricing: where break-even sits

Per-token billing beats a subscription until you cross a usage threshold.

Monthly agent stepsMuse Code StandardMuse Code ContributorClaude Code Pro
50$4.39$0.33$17–20
100$8.78$0.66$17–20
200$17.55$1.32$17–20
250$21.94$1.65$17–20

1,000$87.75$6.60$17–20
3,000$263.25$19.80$17–20

One agent step = 60,000 input plus 3,000 output tokens, no cache hit: $0.0878 on Muse Code Standard, $0.0066 on Contributor. Against a $20 Pro plan, Standard breaks even near 228 steps a month, Contributor near 3,030; cache reuse at $0.15 per M pushes Standard past 900. Tier detail: Muse Code pricing.

Workflow differences that change your day

Four differences beyond the spec sheet, visible within the first hour.

Append-only event log vs session resume

Muse Code writes a local append-only event log, so restarts are replay-exact: kill it mid-task and it rebuilds state from the log, not a snapshot. Claude Code documents session resume instead.

Four binaries vs Windows and a desktop app

The Muse Code launcher hard-codes four targets: arm64 and x86 for macOS and Linux, with no desktop app or IDE extension. Claude Code runs natively on Windows and adds a desktop app, which matters if a reviewer avoids the shell. WSL2 is the Muse Code workaround: unsupported, and it complicates sign-in.

An uncapped meter vs a flat bill

Muse Code cannot take a hard spending ceiling — email alerts, not a stop — so the community fix is a virtual card limit or a per-key cap via OpenRouter. A Claude Code subscription inverts that risk.

Three named skills vs a documented surface

Muse Code ships three named skills: /plan for an approval-gated plan, /grill to stress-test it, /goal to drive an objective. Community reports suggest more — see Muse Code skills and plugins.

Data and privacy policies side by side

The cheapest Muse Code tier is cheap because you pay in training rights.

The two Muse Code tiers carry different data terms. Standard, at $1.25 and $4.25 per million tokens, is stated not to train on your prompts or completions. Contributor, at $0.10 and $0.20, takes training rights over both — that grant buys the roughly 12.5× input and 21.25× output discount — and is country-limited and throttled to 60 requests per minute.

Anthropic publishes its own commercial data terms; we link rather than paraphrase them: Anthropic pricing page and Claude Code documentation. Claude Code has no tier trading training rights for a discount, so the choice Muse Code puts to you does not exist there.

For teams: stay on Standard unless legal has signed off on the training grant, and note that the event log keeps a local transcript on a shared machine. Clause-by-clause: Muse Code privacy; sign-in: how to install Muse Code.

Frequently Asked Questions

Muse Code vs Claude Code — which should I actually use?

Use Muse Code if you are on macOS or Linux and your usage is bursty enough that per-token billing beats a subscription; use Claude Code for Windows, a desktop app or enterprise controls. Meta reports a 3.8-point Terminal-Bench gap — smaller than the gap between a terminal-only agent and a cross-platform one.

Is Muse Code cheaper than Claude Code?

Below roughly 228 agent steps a month, yes. Muse Code Standard costs about $0.088 per 60K-in/3K-out step, so a $20 Claude Code Pro plan wins past that volume. On Contributor, at $0.10 / $0.20 per million tokens, Muse Code stays cheaper until roughly 3,030 steps — paid for in training rights.

How does Muse Code rank compared to Claude Code on benchmarks?

Slightly behind on Meta's own reported figures: Terminal-Bench 2.1 of 82.9% for Muse Spark 1.2 against 86.7% for Claude Opus 5, and DeepSWE 59.3 against 65.0. Those are vendor numbers relayed by press. Artificial Analysis independently measured Muse Spark 1.2 at 80%, with no matching Opus 5 run in our sources.

Can I run Muse Code on Windows the way I run Claude Code?

No. Muse Code publishes only four binaries — arm64 and x86 for macOS and Linux — while Claude Code runs natively on Windows. WSL2 is the community workaround, but Meta has not committed to supporting it and the browser-based OAuth sign-in makes it fiddly.

Does Muse Code have skills, hooks and MCP like Claude Code?

Partly. Muse Code ships three documented skills: /plan, /grill and /goal. Community reports suggest around ten bundled skills plus a hidden plugin system with hooks and MCP servers, but none of that is officially documented — treat it as unconfirmed. Claude Code documents skills, hooks and MCP today, which matters if you build tooling on it.

Does Meta train on my code if I use Muse Code?

Only on the Contributor tier. Standard, at $1.25 / $4.25 per million tokens, is stated not to train on your prompts or completions. Contributor drops to $0.10 / $0.20 precisely because you grant Meta training rights over both. Keep confidential work on Standard.

Can I use Muse Code and Claude Code together?

Yes. Because Muse Code bills per token with no subscription, keeping it installed costs nothing while idle — unlike a monthly plan. A common pattern is a Claude Code subscription for everyday work plus Muse Code, or Muse Spark 1.2 via OpenRouter, for cheap batch jobs.
