Muse Spark vs Claude: Models, Agents and Prices Compared
Muse Spark vs Claude, compared like with like: model scores and cost per task, the Muse and Claude Cowork agents, and plan prices checked in September 2026.
The short answer first. On the main independent index, Claude’s top models score higher than Muse Spark. Muse Spark is cheaper to run per task. Both of those are true at once, and which one matters depends on what you are doing.
The harder part is that "Muse Spark vs Claude" can mean three different comparisons. Meta uses the Muse name for a model and for an agent app, and Anthropic uses Claude for a family of models, a chat app and an agent called Cowork. Comparing Meta’s errand agent with Anthropic’s chat model, or the other way round, produces a verdict about nothing. So this post takes each pairing separately: model against model, agent against agent, plan against plan.
What is being compared
Muse Spark is Meta’s AI model, the first from Meta Superintelligence Labs, and it powers the Meta AI app and meta.ai. Muse is a separate thing: a personal agent app that Meta launched on 8 September 2026, running on Muse Spark. If the naming is new to you, What Is Muse Spark? untangles the model, the app and the rest of the family.
On Anthropic’s side, the models that matter here are Claude Opus 5 and Claude Fable 5.1. Claude Cowork is Anthropic’s agent for knowledge work, and TechCrunch names it as one of the products Muse competes with. Meta’s coding agent against Anthropic’s is its own question, covered in Muse Code vs Claude Code, so it is left out below.
The criteria
- Model quality on an independent benchmark, not on the vendor’s own chart.
- Cost, both per task and per million tokens through the API.
- What the agent is built to do, and which tools and apps it connects to.
- Control: what it asks before acting, and what happens to your data.
- Availability and plan prices, from each company’s own pages.
All of the figures below are as of September 2026. Model versions in this category change every few weeks, so treat the numbers as a snapshot rather than a standing verdict.
Model vs model: Muse Spark 1.3 and Claude Opus 5
Artificial Analysis runs the same set of tests across models and publishes a single Intelligence Index. In its 2 September results, Claude Fable 5.1 at max effort scored 66, the highest on that list. Claude Opus 5 at max effort scored 63. Muse Spark 1.3 at its public xhigh setting scored 61, level with Claude Opus 5 at high effort. A max-effort Muse Spark 1.3 scored 62, but that setting was a partner-only preview, so most people cannot use it.
So on quality, Claude leads at the top end. At the settings most people would actually run, Muse Spark 1.3 and Opus 5 on high sit on the same score.
Cost is where the order flips. Running the index cost $0.55 per task for Muse Spark 1.3 at xhigh, against $1.23 per task for Claude Opus 5 at high. For the same index score, Muse Spark did the work for well under half the price.
The list prices point the same way. Muse Spark 1.3 costs $1.25 per million input tokens and $4.25 per million output tokens on the standard API tier, with a one-million-token context window. Claude Opus 5 lists at $5 per million input tokens and $25 per million output, and Claude Sonnet 5 at $2 and $10.
Two details sit behind those prices. Meta says Muse Spark 1.3 uses about 25% fewer tokens than version 1.2 and is better at long multi-step tasks, which partly explains the low cost per task. Meta also offers a cheaper contributor tier, but it requires letting Meta use your prompts for training, which many companies will not accept for their own data.
Claude scores higher at the top of the index. Muse Spark is cheaper for a similar score. Neither fact cancels the other.
One caveat belongs next to every benchmark. An index measures a fixed set of test questions, not your contracts or your spreadsheets. Artificial Analysis also recorded small declines for Muse Spark 1.3 on a legal reasoning test and on knowledge tests, which shows how much a single headline score hides. Whichever model you use, checking an AI answer when you are not the expert is still your job.
Agent vs agent: Muse and Claude Cowork
These two are both agents, but they are aimed at different parts of your life. Neither is a worse version of the other.
Muse is built for personal errands. Meta says it can send emails, book travel, lower bills, fill out forms and make purchases, and keeps working after you close the app. It can open a browser to fill in forms, and you can talk to it in the app or through WhatsApp. Payments run through Link by Stripe. It asks for approval before it sends an email or makes a purchase, and you choose which apps it connects to and how much access each one gets. At launch it is rolling out in the US only, on iOS, Android and muse.ai.
Claude Cowork is built for knowledge work. It works in the folders and apps you choose, with connectors including Microsoft 365, Google Drive and Slack, plus a built-in browser. It can run scheduled recurring tasks, shows each step it takes, and keeps working with your laptop closed. It runs as a desktop app on macOS, Windows, Linux and ChromeOS, with web and mobile in beta, and it is only on paid plans.
Put plainly, Muse is aimed at the jobs you do for your household, and Cowork at the jobs you do with documents for an employer. Handing either one real tasks follows the same logic as using AI as an executive assistant: give it the repeatable work, and keep the judgement calls.
On data, Meta says Muse runs on a dedicated cloud machine and doesn’t share your conversations or VM data with its ad systems. You can opt out of your interactions being used to train Meta’s models, ask it to forget things, and disconnect services at any time. Whether that is enough for an agent that can spend money is a fair question, and Is Meta Muse Safe? goes through it in more detail.
Plans and prices
Muse has three tiers: Free with a usage meter, Power at $20 a month and Maximum at $100 a month. A payment card is required to start, even on the free tier. The full breakdown is in Meta Muse pricing.
Claude has a free plan at $0, Pro at $20 a month or $17 a month billed annually, and Max from $100 a month. Pro is the first tier that includes Claude Cowork and Claude Code. The free plan still covers chat, web search, memory, file creation and connectors.
The paid price points line up closely on both sides. The difference is what you get at zero. Muse’s free tier includes the agent itself, with limits. Claude’s free tier is chat only, and the agent starts at Pro.
Meta AI vs Claude, the chat apps
If what you really mean is the everyday chatbot, the pairing is the Meta AI app against the Claude app. Meta AI runs on Muse Spark. In a hands-on test at launch, Simon Willison found that meta.ai needs a Facebook or Instagram login, and that the chat could run Python, search the web, generate images and search public posts on Instagram, Threads and Facebook. Claude’s free plan works on web, iOS, Android and desktop. If you do not use Meta’s apps, that login requirement may decide it before anything else does.
How to choose
- You want an agent to handle personal errands, bookings and purchases, and you are in the US. Muse is built for exactly that, and you can try it on the free tier.
- You want an agent to work through files, email and work apps such as Microsoft 365 or Slack. Claude Cowork is built for that, on a paid plan.
- You are building on an API and cost per task decides the project. Muse Spark 1.3 did the index for less than half of Claude Opus 5’s cost at a matching score.
- You need the highest score available and the budget is secondary. Claude Fable 5.1 and Opus 5 at max effort sit at the top of the index.
- Your data cannot be used for training. Avoid Meta’s contributor API tier, and read the terms of whichever plan you pick.
The most useful test is not on any chart. Take one repetitive task from your own week and run it through both, a method set out in Workflow AI. The tool that gets that task right with fewer corrections is the better choice for you, whatever the index says.
The caveat
Everything above describes a single month. Muse Spark 1.3 arrived on 2 September, and Muse itself is days old. Both companies will ship again before this post is a quarter old, so check the pricing page before you pay and rerun your own test when a new version lands.
An agent that sends email or spends money also changes what a mistake costs. These systems can be confidently wrong, as What AI Is Actually Bad At explains, so keep the approval steps switched on for anything you cannot easily undo.
The model matters less than knowing what to ask and how to check the answer. Coursium teaches people to use AI at work, in short lessons on iPhone, and more about it is on the Coursium home page.
