Muse Wonder Pricing Explained: API Costs, Muse Code Tiers, and 429 Errors
Muse Wonder and Muse Wonder Full pricing, Muse Code subscription tiers, API token costs versus GPT 6.1 Soul and Opus 5.5, and the quota errors at launch.
What does Muse Wonder cost, and why did early users hit quota errors right away?
Meta’s Muse Wonder costs $4 per million input tokens and $20 per million output tokens through the API, with cached input priced at 20 cents per million tokens. That puts it close to competitors like GPT 6.1 Soul and Claude Opus 5.5 on paper, but the bigger story at launch wasn’t the price sheet, it was access. Muse Wonder Full, the stronger of the two new models, isn’t available through the API at all. The only way to use it is through a Muse Code subscription, and multiple early users burned through their quota in minutes even on the top $200 tier, triggering a wave of 429 (rate limit) errors.
TL;DR
- Muse Wonder is priced at $4 per million input tokens and $20 per million output tokens via the API, with cached input at 20 cents per million, making it roughly double the per-token cost of GPT 6.1 Soul’s $2 input / $10 output pricing.
- Muse Wonder Full has no public API. It only ships inside Muse Code, Meta’s terminal-based coding agent, gated behind the $50 or $200 monthly subscription tiers.
- Early testers reported running out of quota almost immediately, with one user hitting 429 errors within three minutes of subscribing to the $50 plan and again after upgrading to $200.
- Meta’s own AI chief, Alexander Wang, publicly acknowledged the quota problem on social media, saying the issue was known and being fixed.
- On cost-per-completed-task metrics tracked by Artificial Analysis, Muse Wonder Max came in around $4.52 per task, in the same range as Claude Sonnet, Opus, and Mistral’s Le Chat-class models, but notably pricier than cheaper alternatives like Gemini’s upcoming Argon model.
- Despite strong benchmark scores, Muse Wonder lands in the “expensive but capable” quadrant on intelligence-versus-cost charts rather than the ideal low-cost, high-intelligence corner.
- The $15 entry-level Muse Code plan does not include access to Muse Wonder Full, a detail that surprised at least one reviewer who expected it to be included before upgrading twice to find enough quota.

How is Muse Wonder priced compared to GPT 6.1 Soul and Opus 5.5?
Muse Wonder’s API pricing sits at $4 per million input tokens and $20 per million output tokens, with cached input at 20 cents per million. For comparison, GPT 6.1 Soul runs $2 per million input and $10 per million output for short context (roughly double that for long context), meaning Muse Wonder costs about twice as much per token on the output side. Claude Opus 5.5 is priced at $420 per million tokens for input and output respectively, in a different pricing structure that one reviewer described as landing in a similar overall cost range once usage patterns are accounted for.
Token pricing alone doesn’t tell the full story, though. Artificial Analysis also tracks cost-per-completed-task, which blends price with how many tokens a model actually burns through to finish a job. On that metric, Muse Wonder Max came in at $4.52 per task, roughly in line with open-source model Qwen3-8B and in the same ballpark as Sonnet, Opus, and Mistral’s flagship models, which clustered closer to $7.63. Cheaper options existed too: an unreleased Gemini model (referred to as “Argon”) was tracked at around $2 per task, and GPT 6.1 Soul Max came in notably cheaper than Muse Wonder on a cost-adjusted basis, which is part of why one reviewer called Soul Max the better overall value despite Muse Wonder’s competitive raw benchmark scores.
On the intelligence-versus-cost quadrant chart that Artificial Analysis publishes, the ideal position is high intelligence paired with low cost. Muse Wonder Max landed in the high-intelligence, high-cost quadrant instead, meaning it performs well but isn’t cheap to run at scale.
What’s the difference between Muse Wonder and Muse Wonder Full?
Muse Wonder is the version available through Meta’s model API and inside Muse Code. Muse Wonder Full is the larger, stronger model, and as of launch it has no public API access whatsoever. The only path to using it is a paid Muse Code subscription on either the $50 or $200 monthly tier. Artificial Analysis even marked Muse Wonder Full on its leaderboard as having “no publicly available API,” a flag usually reserved for research previews or closed internal models.
This two-tier structure is a notable shift for Meta, which built its AI reputation on open releases like Llama. Muse Wonder itself is fully closed, and Muse Wonder Full is locked even further behind a subscription product rather than pay-as-you-go API access. For developers used to integrating a model directly into their own applications, that means Muse Wonder Full currently isn’t an option at all. You get it only as an assistant inside Meta’s coding tool, not as infrastructure you can build on.
What are the Muse Code subscription tiers, and what do you actually get?
Remy doesn't build the plumbing. It inherits it.
Other agents wire up auth, databases, models, and integrations from scratch every time you ask them to build something.

Muse Code offers at least three paid tiers based on user reports: an entry-level $15 per month plan, a $50 per month plan, and a $200 per month plan. The $15 tier does not include access to Muse Wonder Full. One reviewer subscribed expecting the entry plan to be enough for testing, only to discover the full model required an upgrade.
After moving to the $50 plan, that same user ran out of usage quota within roughly three minutes, hitting repeated 429 errors (the standard HTTP status code for “too many requests”). Expecting the $200 tier to solve the problem, they upgraded again and still ran into the same rate limiting almost immediately. The pattern suggests Meta’s backend capacity, or its quota allocation per tier, wasn’t calibrated for the demand that showed up in the first hours after launch.
Did Meta acknowledge the quota and access problems?
Yes. After a user posted publicly about repeatedly hitting 429 errors across both the $50 and $200 Muse Code tiers, Alexander Wang, Meta’s chief AI officer and the former Scale AI founder now leading Meta Superintelligence Labs, replied directly. He said the issue was known and that the team was fixing it. That kind of direct, fast acknowledgment from a lab’s leadership is common during high-demand launches, but it also confirms the quota problems weren’t isolated to one user’s account or an unusual edge case. They were a broader capacity issue at launch.
This lines up with the general pattern seen whenever a lab ships a frontier-class model to a sudden wave of signups: demand for compute spikes far faster than rate limits can be adjusted, and early adopters eat the consequences in the form of throttled or blocked requests.
Is Muse Wonder worth the cost right now?
That depends on what you’re optimizing for. On raw capability, Muse Wonder and Muse Wonder Full post strong numbers, landing near Claude Opus 5.5 and ahead of GPT6 Astra on several independent benchmarks, including the Artificial Analysis Intelligence Index where Muse Wonder Full scored 56 against Opus 5.5’s 58. But capability and value aren’t the same thing. On cost-per-task, Muse Wonder sits in the upper range alongside Opus and Sonnet rather than in the cheaper tier occupied by models like GPT 6.1 Soul Max, which one reviewer explicitly called the better overall deal once quota, intelligence, and price are weighed together.
For teams building with the API today, Muse Wonder (the non-Full version) is the only option, at $4/$20 per million tokens for input/output. For anyone wanting the stronger Muse Wonder Full model, the calculus is different: you’re paying a flat monthly fee for access through Muse Code specifically, with no guarantee of stable throughput given the quota issues reported immediately after launch. Anyone evaluating it for production use right now should expect further pricing and rate-limit adjustments as Meta works through the scaling problems Wang acknowledged.
