Muse Wonder vs Muse Spark: Which Meta Model, Where and at What Price
Muse Wonder costs $4 / $20 per million tokens against $1.25 / $4.25 for Muse Spark, Wonder Full is only in Muse Code's $50 and $200 plans, and the Muse agent app still runs on Spark.
UpdatedOctober 22, 2026
In short
Use Muse Spark for everyday work and the Muse agent, and Muse Wonder when the task is long or complex software work. On Meta's Model API, Wonder costs $4 per million input tokens and $20 per million output tokens, about three to five times Spark's $1.25 and $4.25. Muse Wonder Full, the stronger variant, is not on the API at all: it comes only with Muse Code's Power Usage plan at $50 a month or Maximum Usage at $200. The Muse agent app itself still runs on Spark; Meta says Wonder will reach it soon, subscribers first.

Three models, three ways to get them
Each model reaches you through a different product. Read the second column first: it decides which models you can use before price matters.
| Muse Spark | Muse Wonder | Muse Wonder Full |
|---|---|---|---|
Where | Muse agent app, Model API, every Muse Code plan | Model API, every Muse Code plan | Muse Code Power and Maximum only |
API price per 1M tokens (input / cached / output) | $1.25 / $0.15 / $4.25 | $4.00 / $0.20 / $20.00 | Not on the API |
Cheaper Contributor mode | $0.10 / $0.002 / $0.20 (1.3 and 1.2) | Not offered | Not applicable |
Context window | 1,048,576 tokens | 1,048,576 tokens | 1M tokens |
Status | Versions 1.1 to 1.3; 1.3 recommended | Preview | Muse Code subscribers only |
Neither model charges more for a full context window, so long documents cost the same per token as short prompts.
What the price gap means for a task
As an illustration, take a coding task that reads 1 million tokens and writes 200,000. On the API it costs about $8.00 on Muse Wonder ($4.00 input, $4.00 output) and about $2.10 on Muse Spark ($1.25 and $0.85). Output is where the gap widens: Wonder's output price is nearly five times Spark's, so tasks that write a lot, such as code generation, feel the difference more than tasks that mostly read.
Muse Spark also has Contributor mode, which cuts its API price to $0.10 input and $0.20 output in exchange for letting Meta train on your content. Wonder has no such mode.
Wonder against Wonder Full in Meta's own numbers
Meta's benchmark table compares Wonder and Wonder Full at maximum effort, and these are Meta's figures, not independent results. Wonder Full leads on every coding row, but not by much on some: 79.0 against 78.8 on DeepSWE 1.1, 57.5 (at xhigh effort) against 53.1 on SWE-Marathon, and 57.1 against 52.0 on Terminal-Bench 4.0-AA. On the Artificial Analysis Index Meta reports 56 and 52. Meta describes Wonder as offering performance comparable to Wonder Full. Spark is not in the table, so Meta publishes no direct Wonder-versus-Spark score.
Muse Code is the cheapest way to try both
For a developer who works in a terminal, a Muse Code subscription can cost less than the API. The $5 Everyday Usage plan includes Spark and Wonder at 10 to 50 prompts every five hours; High Usage at $15 gives five times that. Wonder Full needs Power Usage at $50, with 20 times Everyday's usage, or Maximum Usage at $200 with 80 times. All plans reset every five hours and weekly. Muse Code plans default to Contributor mode, which buys more usage in exchange for training on your content, and you can switch it off.
Wonder and Wonder Full are not available in South Korea.

FAQ
Common questions
Is Muse Wonder better than Muse Spark?
Meta positions Wonder as its most capable model for complex software engineering and long agentic tasks, and Spark as the general model behind the Muse agent. Meta's benchmark table covers Wonder and Wonder Full, not Spark, so it gives no head-to-head score.
How much does Muse Wonder cost on the API?
$4 per million input tokens, $0.20 cached and $20 per million output tokens, in Standard mode only. Muse Spark costs $1.25, $0.15 and $4.25, or less in Contributor mode.
How do I get Muse Wonder Full?
Only through a Muse Code subscription on the Power Usage plan ($50 a month) or Maximum Usage ($200). It is not on the Model API.
Does the Muse app use Muse Wonder?
Not yet. Muse launched on Muse Spark, and Meta says Wonder will soon power more of Muse, first for subscribers, without giving a date.
