Muse Spark vs GPT vs Claude: The Short Answer
Meta's Muse Spark costs $1.25 per million input tokens and $4.25 per million output tokens: the same input price as GPT-5, at less than half the output price. It also prices below every current Claude model on output, where the floor is Claude Haiku 4.5 at $5.00.
That asymmetry is the whole cost argument. Most teams compare models on the input number because it is the first column on every pricing page. Output is where agent loops, code generation and long-form drafting actually spend.
One caveat before the tables: small-model tiers undercut it outright. GPT-5 mini runs $2.00 per million output tokens, GPT-5 nano $0.40.
Meta runs no startup credit program for Muse. AI Perks tracks $7.7M in credits across 194 companies covering the alternatives.
What Meta Shipped in 2026, and When
Meta Superintelligence Labs, under chief AI officer Alexandr Wang, built out the entire Muse line between April and September 2026. The consumer agent everyone is searching for arrived last, not first.
| Date (2026) | Release | What it is |
|---|---|---|
| Apr 8 | Muse Spark | The foundation model |
| Jul 7 | Muse Image | Image generation |
| Jul 9 | Muse Spark 1.1 + Meta Model API | Self-serve public preview |
| Jul | Muse Video | Previewed |
| Aug 5 | Muse Code | Coding agent for large codebases |
| Sep 8 | Muse | Consumer "personal AI agent" |
July 9 is the date that matters for builders: the Meta Model API entered self-serve public preview with OpenAI SDK compatibility, which means swapping a base URL and a key rather than rewriting an integration.
Evaluating Muse Spark is therefore cheap: the decision reduces to price and output quality instead of engineering time.
Muse Spark API Pricing Against GPT and Claude
At $1.25 input and $4.25 output per million tokens, Muse Spark 1.1, 1.2 and 1.3 all carry the same price, and all of them land below the full-size GPT and Claude models on a balanced workload.
| Model | Input /1M | Output /1M | Output multiple | 1M in + 1M out |
|---|---|---|---|---|
| Muse Spark (Contributor tier) | $0.10 | $0.20 | 2.0x | $0.30 |
| GPT-5 mini (legacy) | $0.25 | $2.00 | 8.0x | $2.25 |
| Muse Spark (standard) | $1.25 | $4.25 | 3.4x | $5.50 |
| Claude Haiku 4.5 | $1.00 | $5.00 | 5.0x | $6.00 |
| GPT-5 (legacy) | $1.25 | $10.00 | 8.0x | $11.25 |
| Claude Sonnet 5 | $2.00 | $10.00 | 5.0x | $12.00 |
| GPT-5.6-Terra | $2.00 | $12.00 | 6.0x | $14.00 |
| Claude Opus 5 | $5.00 | $25.00 | 5.0x | $30.00 |
| GPT-6 Astra | $10.00 | $50.00 | 5.0x | $60.00 |
One thing the table cannot show: GPT-5, GPT-5 mini and GPT-5 nano are scheduled for API shutdown on 10 December 2026. They are listed because they are still the reference point most comparisons use, but do not architect against them. The live OpenAI line is GPT-5.4, GPT-5.6 and GPT-6 Astra.
Read the output multiple column. The category clusters at 5x: output costs five times input across Haiku, Sonnet, Opus and Astra. GPT-5 sits at 8x. Muse Spark sits at 3.4x.
The effect is that Muse Spark's advantage grows with output volume. If your product classifies or summarises, the gap barely registers. If it runs agent loops that generate thousands of tokens per turn, the gap compounds on every call.
Note the GPT-5 mini row. Muse Spark is not the cheapest way to generate a token. It is the cheapest full-size model in this set, and if your workload runs happily on a small model, that is a different and cheaper decision.
Two things this table cannot tell you: how these models score against each other, and how much context each accepts. Benchmark results, context windows and parameter counts for Muse Spark sit outside what this comparison verified, so treat any figure quoted for them as unconfirmed until you check Meta's own documentation. Price is knowable today. Fit is not.
Meta also lists Muse Image at $0.01 per image and Muse Voice Transcribe at $3.00 per 1,000 minutes. Price those separately, because multimodal rates rarely move in step with text rates. AI Perks tracks credits across these categories.
The Contributor Tier: Your Data for a 40x Discount
Meta offers a "Contributor" tier at $0.10 input and $0.20 output per million tokens, and in exchange it trains on your prompts and completions.
That is $0.30 for the balanced workload above. Against Claude Sonnet 5 at $12.00 it is 40x cheaper. Against Claude Opus 5, 100x. Against GPT-6 Astra, 200x.
It is an unusual shape for a public price list. It is not a volume deal and not a startup grant. It is a straight trade of data for price, published as a standard rate.
The decision is not about the discount. It is about what flows through the prompt:
- Internal tooling with no customer data. The trade is usually defensible.
- Anything carrying customer records, health data or financial data. It is not.
- Anything under a customer DPA or enterprise NDA. Check the contract first.
- Your own system prompts and proprietary instructions. Those go to Meta too, and for many teams that is the actual asset.
Founders who want a low number without the data trade should look at credits on a standard tier. AI Perks covers 194 companies offering exactly that.
Muse AI vs ChatGPT: What the Consumer Agent Costs
Muse, launched 8 September 2026, is a personal AI agent that proactively completes tasks: booking, filling forms, sending emails and making purchases. It runs on a Meta-cloud virtual machine with a visible browser, so you can watch it work.
The permissions layer is called Sentinel. An agent authorised to spend money needs a permission model users can reason about, and Meta gave that layer a product name instead of burying it in a settings screen.
Muse ships on iOS, Android, WhatsApp and the web at muse.ai, with AI glasses listed as coming soon. WhatsApp is the real distribution story here. An agent that opens inside a messaging app people already have installed skips the download step entirely.
Pricing is a free tier, Power at $20 per month and Maximum at $100 per month. The tiers are separated by usage volume rather than by features, so the choice is about how much you run, not about what you unlock.
Meta has not published task or token ceilings for any tier, including the free one, so nobody can tell you what that free tier is actually worth.
The muse.ai Name Collision, Explained
Three unrelated things are called Muse, and they are easy to confuse.
| "Muse" | Who | What |
|---|---|---|
| Muse / Muse Spark | Meta Superintelligence Labs | The 2026 model family and consumer agent |
| muse.ai (until March 2026) | Antonio Roldao's company | Video hosting and search, now SKIV |
| Muse (Feb 2025) | Microsoft Research | WHAM, a gameplay generation model |
The independent muse.ai rebranded to SKIV on 3 March 2026, with an embed-URL migration deadline of 10 March. Meta subsequently took over the vacated domain as the web front end for its agent.
Microsoft's Muse, built with Xbox Game Studios and Ninja Theory, has no connection to Meta at all.
If you go searching for Muse documentation and land on video hosting or Xbox research, this is why.
Are There Meta Muse Startup Credits?
No. Meta runs no dedicated startup or credit program for Muse, Muse Spark or the Meta Model API. Its developer-programs page lists Meta Horizon Start and the Meta Horizon Creator Program, both VR and MR only, neither connected to Muse.
Meta does run a Llama Startup Program for compute credits. Whether that extends to Muse Spark is unconfirmed either way.
Third-party blogs claim new Meta Model API accounts receive $20 in free credits. That figure does not appear on Meta's official pricing page, so treat it as unverified.
This is the honest gap in the comparison. Building on Muse Spark means paying list price from the first token, while the same product built elsewhere may be able to start on credits instead.
| Category | What credits look like |
|---|---|
| Meta Muse Spark | No program published |
| Everywhere else in the stack | 194 companies with tracked offers |
| Combined value tracked | $7.7M |

Frequently Asked Questions
Is Muse Spark cheaper than GPT?
Against GPT-5, yes on output: $1.25 per million input tokens for both, and $4.25 against GPT-5's $10.00 on output. On a balanced million-in, million-out workload that is $5.50 versus $11.25. Against the smaller GPT tiers, no: GPT-5 mini runs $2.00 per million output tokens. Credits change the maths, and AI Perks tracks them.
How does Muse Spark compare to Claude on price?
Muse Spark undercuts every current Claude model on output tokens, including Claude Haiku 4.5 at $5.00 per million, which is the cheapest output price in the Claude lineup. Claude Sonnet 5 runs $2.00 and $10.00, Claude Opus 5 runs $5.00 and $25.00. Benchmark comparisons behind those prices are not verified here, so price is the only axis this answer covers.
Does Meta offer free Muse Spark credits?
Meta publishes no startup or credit program for Muse Spark. Its developer-programs page lists VR and MR programs only. Claims of $20 in free API credits circulate on third-party blogs but do not appear on Meta's own pricing page. For credits that are documented, see AI Perks.
What is the Muse Contributor tier?
A discounted Meta Model API tier at $0.10 per million input tokens and $0.20 per million output tokens, roughly 40x cheaper than Claude Sonnet 5 on a balanced workload. In exchange, Meta trains on your prompts and completions. Suitable for internal tooling, unsuitable for anything carrying customer data.
Is muse.ai the same company as Meta's Muse?
No. muse.ai was an independent video hosting and search company that rebranded to SKIV on 3 March 2026. Meta later took over the vacated domain as the web front end for its agent. Microsoft's Muse, from February 2025, is a separate gameplay-generation research model with no Meta connection.
How much does the Muse consumer app cost?
Muse offers a free tier, Power at $20 per month and Maximum at $100 per month. The tiers differ by usage volume rather than by features, so paying more buys throughput, not capabilities. Meta has not published the task or token ceilings on any tier, including the free one.
