Muse Wonder

Meta's most capable Muse model for agents, knowledge work and coding, with a 1M-⁠token context window

About Muse Wonder

Muse Wonder is Meta's most capable Muse model, built for agents, knowledge work and coding. It reads text, images, video, audio and PDFs, holds up to 1 million tokens in one conversation, and keeps working on a hard task by trying other approaches before it gives up

Muse Wonder scores 68.1% on AutomationBench, ahead of GPT-⁠6.1 Terra at 60.2%, and 30.6% on GDP.pdf, one of the ten best results of any model on questions about long professional PDFs. When it doesn't know the answer to a knowledge question, it says so instead of making one up in 79.1% of cases

On Overchat AI, Muse Wonder is in the same chat as Muse Spark, Claude and GPT-⁠6, so you can ask it, attach a file and switch models without starting over

Examples of Muse Wonder answers to 3 prompts: Find what's wrong, Simulate a pendulum and Check a fact. Each answer is the unedited output of the model

My online store's last six months: visits 42k, 45k, 47k, 51k, 50k, 53k; orders 1,260, 1,280, 1,240, 1,230, 1,150, 1,140; refunds 38, 41, 52, 66, 71, 80. Find the two biggest problems and suggest one fix for each, in a short table.

Muse Wonder
Problem Evidence (Month 1 → 6) Fix
1. Falling conversion rate Visits up 42k → 53k (+26%), but orders down 1,260 → 1,140. Conversion fell 3.0% → 2.15%. Audit the new traffic source and align its landing page to the ad/search intent.
2. Rising refund rate Refunds up 38 → 80; refund rate more than doubled, 3.0% → 7.0% of orders. Identify the #1 refund reason for the top product and fix it (e.g., sizing/description or quality).

Write a Python function that simulates a damped pendulum with the RK4 method and returns the angle over time. Keep it under 40 lines and explain your choice of time step in one sentence.

Muse Wonder
python
import numpy as np

def simulate_damped_pendulum(theta0=1.0, omega0=0.0, t_max=10.0,
                             dt=0.01, g=9.81, L=1.0, damping=0.1):
    n = int(t_max / dt) + 1
    t = np.linspace(0, t_max, n)
    theta = np.empty(n)
    omega = np.empty(n)
    theta[0], omega[0] = theta0, omega0

    def deriv(th, om):
        return om, -(g / L) * np.sin(th) - damping * om

    for i in range(n - 1):
        th, om = theta[i], omega[i]
        k1_th, k1_om = deriv(th, om)
        k2_th, k2_om = deriv(th + 0.5 * dt * k1_th, om + 0.5 * dt * k1_om)
        k3_th, k3_om = deriv(th + 0.5 * dt * k2_th, om + 0.5 * dt * k2_om)
        k4_th, k4_om = deriv(th + dt * k3_th, om + dt * k3_om)
        theta[i + 1] = th + (dt / 6) * (k1_th + 2 * k2_th + 2 * k3_th + k4_th)
        omega[i + 1] = om + (dt / 6) * (k1_om + 2 * k2_om + 2 * k3_om + k4_om)

    return t, theta

I chose dt=0.01 s because it is far smaller than the pendulum's ~2 s natural period, so RK4 remains accurate and stable without unnecessary computation.

Who was the first person to walk on the Moon, and who was the 13th? If any part of the question has no real answer, say so instead of guessing.

Muse Wonder

The first person to walk on the Moon was Neil Armstrong of Apollo 11, on July 20, 1969 (EDT).

There is no 13th person — only 12 people in total have walked on the Moon, all Apollo astronauts between 1969 and 1972.
