What is Muse Wonder?

Muse Wonder is a frontier AI model from Meta Superintelligence Labs, released on October 12, 2026. It belongs to Meta's Muse family, next to Muse Spark and Muse Image, and is not a Llama model. There are two versions: Muse Wonder, which developers can call through Meta's API, and Muse Wonder Full, Meta's most capable variant, which comes only with a Muse Code subscription.

Meta built it around two ideas. Active Memory carries what it knows about you across conversations and pulls up the details a task needs; Active Focus keeps it working towards a hard goal, trying other approaches when it gets stuck and checking in before important actions. It reads text, images, video, audio and PDFs within a 1-million-token context window, answers in text, and its weights are not public.

Muse Wonder does not create images or video. Meta's image model is the separate Muse Image, and Muse Video has been shown but not released. If you came here to make pictures, Nano AI runs Nano Banana 2.1 and other image models in the browser.

Muse Wonder API quickstart

Muse Wonder is in Meta's Model API as muse-wonder-1.0, at https://api.meta.ai/v1. It works with the OpenAI SDK (Responses and Chat Completions) and the Anthropic SDK (Messages).

  1. 1

    Create an API key

    Sign in at dev.meta.ai with a Meta account, open API keys in the dashboard and choose Create API key. Keep it in an environment variable.

    export MODEL_API_KEY=your_key_here
  2. 2

    Send a first request

    This is Meta's own sample request, with a reasoning effort set:

    curl -X POST "https://api.meta.ai/v1/responses" \
      -H "Authorization: Bearer $MODEL_API_KEY" \
      -H "Content-Type: application/json" \
      -d '{"model":"muse-wonder-1.0","reasoning":{"effort":"high"},"input":"Summarise this contract in five bullet points."}'
  3. 3

    Or use the OpenAI SDK

    Point the client at Meta's base URL. The SDK does not read MODEL_API_KEY by itself, so pass the key explicitly.

    import os
    from openai import OpenAI
    
    client = OpenAI(base_url="https://api.meta.ai/v1", api_key=os.environ["MODEL_API_KEY"])
    response = client.responses.create(
        model="muse-wonder-1.0",
        reasoning={"effort": "high"},
        input="Plan a three-day trip to Kyoto.",
    )
    print(response.output_text)
  4. 4

    Choose a reasoning effort

    Effort can be minimal, low, medium, high, xhigh or max; leave it out and the model picks. Reasoning cannot be switched off (none returns HTTP 400), and max does not turn it into Muse Wonder Full.

  5. 5

    Or code with Muse Code

    Meta's command-line coding agent for macOS and Windows. Every plan includes Muse Wonder; Power and Maximum add Muse Wonder Full.

    curl -fsSL https://dev.meta.ai/install.sh | bash

What Muse Wonder is good at, and where it trails

01

Active Memory

Meta's MemoryBench puts Muse Wonder at 85.6, ahead of Claude Opus 5.5 (81.5) and GPT-6 Astra (81.4). It is Meta's own test, so treat it as a claim.

02

Active Focus on long tasks

Muse Wonder Full leads Meta's table on long coding work: 79.0 on DeepSWE 1.1 and 57.5 on SWE-Marathon, against 74.2 and 46.3 for Claude Opus 5.5.

03

Second in Text Arena

On October 13 Muse Wonder (max) entered Arena's text leaderboard at second place with 1513, 12 points behind Gemini 4 Argon. Muse Wonder Full reached sixth in WebDev with 1726.

04

1M-token context, same price as Opus

$4 and $20 per million input and output tokens, the same list price as Claude Opus 5.5, with no surcharge for long context.

05

Where Claude Opus 5.5 leads

Opus scores higher on the Artificial Analysis index (58 against 52), on ProgramBench (70.5 against 50.0) and on Terminal-Bench (59.6 against 52.0).

06

What early users criticise

The best scores belong to Muse Wonder Full, which the API does not offer. Hacker News users found taste and judgment behind Opus, and factual recall is weak.

Muse Wonder benchmarks vs Claude Opus 5.5, GPT-6 Astra and Claude Fable 5.1

From Meta's model card, at max reasoning effort (SWE-Marathon for Muse Wonder Full at xhigh). Personal Superintelligence Index and MemoryBench are Meta's own tests. The Artificial Analysis index is the independent v4.3 score; API prices are per 1M input and output tokens.

How to use Muse Wonder

  1. 1

    Through Meta's API

    Create a key at dev.meta.ai and call muse-wonder-1.0 with the OpenAI or Anthropic SDK, or test prompts in the playground at dev.meta.ai/playground. The quickstart is above.

  2. 2

    In Muse Code

    Install Meta's coding agent and pick a plan: Everyday ($5) and High ($15) include Muse Wonder; Power ($50) and Maximum ($200) add Muse Wonder Full.

  3. 3

    In the Muse app

    Meta says Muse Wonder is coming to its Muse app soon, for subscribers first. It is not in the Meta AI app, WhatsApp or Instagram, which run Muse Spark.

Prompts to try with Muse Wonder

Muse Wonder is built for long, multi-step work. The last two turn its answer into an image prompt you can paste into Nano AI.

  • Long task with memory

    Remember that I'm planning a small bakery in Lisbon with a budget of 40,000 euros. Draft a 12-week launch plan, list what you still need to know from me, and keep track of my answers in later messages.

  • Code from a screenshot

    Here is a screenshot of a pricing page. Rebuild it as a single responsive HTML file with Tailwind CSS, then list anything you had to guess.

  • Read a long PDF

    Read the attached annual report and give me the five numbers that changed most since last year, each with its page number.

  • Write image prompts

    Write three detailed image prompts for a product photo of a matte black water bottle on a mossy rock beside a waterfall: one realistic, one minimalist, one isometric. Describe the light, lens and background, and keep each under 60 words.

  • Plan a poster, then make it

    Plan a poster for a Sunday farmers market: give me the headline, two short lines of small text, and a one-paragraph image prompt that includes the exact text in quotation marks.

Muse Wonder limits and gotchas

What the documentation and early users point out.

HTTP 400 when turning reasoning off
Reasoning cannot be disabled. Use minimal effort for the fastest, cheapest answers; reasoning tokens are billed at the output price.
max effort is not Muse Wonder Full
Full is a separate model, only in Muse Code's Power and Maximum plans. The benchmark leader in Meta's table is usually Full.
The OpenAI SDK says the key is missing
It does not read MODEL_API_KEY. Pass api_key and base_url when you create the client.
Not available in South Korea
Meta lists neither Muse Wonder model in South Korea, in the API or in Muse Code.
Memory with zero data retention
Zero-data-retention setups do not keep server-side conversation state, which limits what Active Memory can carry over.
Muse Code trains on your work by default
Subscriptions start in Contributor mode, which lets Meta train on your content. Switch it off in the settings if you need to.
It will not make images or video
Output is text only. Use Muse Image in the Meta AI app, or an image model such as Nano Banana 2.1 on Nano AI.
Weak factual recall
Artificial Analysis rates its factual knowledge low (25 on AA-Omniscience), so check names, dates and figures.
