Four interviews in two weeks. He did not send a single application himself. The job hunt just changed hands. https://t.co/Rl6lX3IPiP

Instacart charged $51 for salmon priced $34 on the package. Two support agents hung up. Muse kept going and got $51 back.

"Check my last Instacart order against the prices printed on the packages I received. Flag anything I was overcharged for, then contact support and get the refund issued. Keep going until the refund email arrives."
Your delivery app should charge the shelf price, not the app price."

Hot take: delegation is not laziness. It is how grown-ups work.

He handed the whole job hunt to his Muse. Four interviews in two weeks, and he never sent one application himself.

It was love at first use. 500,000 reviews at 4.8 stars, and number one in Productivity. People do not rate a demo that high. They rate the agent that does the errand.

Download Muse 🥳

$META Muse has now surpassed 500k reviews on the App Store with a 4.8 star rating.

Safe to say the people like it…

WHOOP charges $239 a year for this view. Your watch already collects the data, and Muse builds the dashboard for free. No band. No subscription.

🚨 You might not need WHOOP anymore

Meta's @Muse connects to Apple Health — and with Spaces, you can build your own WHOOP-style dashboard: recovery score, strain, sleep, everything.

His yearly contacts were $540 at 1-800 Contacts. He had Muse shop the same lenses across 12 sites, and Costco had them for $367, with his insurance confirmed. That is $173 saved.

Same score as Claude Haiku 5.5, a third of the cost per task. Ember is the model that makes the repeat work cheap enough to run all day.

[Artificial Analysis @ArtificialAnlys]

Meta's newest model Muse Ember scores 36 on the Artificial Analysis Intelligence Index, matching Claude Haiku 5.5 (max) at a third of the Cost per Task

Muse Ember is Meta's newest efficient-tier model line, with the same input and output token prices as Claude Haiku 5.5 and GPT-6 Luna

Key Takeaways:

➤ On the Intelligence Index vs. Cost per Task Pareto frontier at both max and xhigh effort. Muse Ember (max) is the cheapest model scoring 36 or higher, at $0.14 per task, and Muse Ember (xhigh) scores 34 for $0.12. Claude Haiku 5.5 (max) costs almost 3x more at $0.41 for the same score as Muse Ember (max). Muse Ember (max) is also about 4x cheaper than DeepSeek V4.1 Flash 1017 (max, 33, $0.60) and GLM-5.3-Flash (28, $0.58)

➤ 8 points behind Muse Wonder for about 1/50th of the Cost per Task. Muse Wonder (max) scores 44 at $6.95 per Intelligence Index task

➤ Stands out on AutomationBench-AA. Muse Ember (max) scores 68.1% on AutomationBench-AA, level with Muse Wonder (max), and beats Claude Haiku 5.5 (max) on GDP.pdf (22.8% vs 20.8%), but trails it on AA-Briefcase (1521 vs 1574 Elo)

➤ Mixed in agentic coding in our Intelligence Index evaluations. It beats Claude Haiku 5.5 (max) on Terminal-Bench 4.0 (40.9% vs 32.8%) but trails it on FrontierCode 2.0 (27.2% vs 34.9%)

➤ Ahead of similarly priced models when running in its own coding agent. In Muse Code, Muse Ember (max) scores 46 on the Artificial Analysis Coding Agent Index, ahead of Claude Haiku 5.5 in Claude Code (max, 37) and GPT-6 Luna in Codex (max, 31)

➤ Knowledge is the main weakness, but it rarely hallucinates. Its AA-Omniscience accuracy of 21.1% is the lowest of the similarly intelligent models we compared, against 34.7% for Claude Haiku 5.5 (max) and 50.5% for Gemini 3.8 Flash (high). This is mostly because it declines to answer 64% of questions, which keeps its hallucination rate at 17.4%, half of Claude Haiku 5.5’s (max)

Other details:
➤ Pricing: $0.10 input / $0.004 cached input / $0.50 output per 1M tokens
➤ Reasoning effort: results shown at max effort, with xhigh also on the Intelligence vs. Cost chart ➤ Availability: Meta's first-party API and Muse Code

Muse 101, Lesson 17 is here. Let it do the boring middle. The start is fun and the finish is yours. The middle is forms, comparisons, and digging. Hand Muse that part. The card has a prompt you can copy and try today.

[Muse Cases User @Musecases]

Her Muse found almost $2,000 in under a month, starting with a $400 invoice she forgot to send.

Bookmark this.

Look through my email, invoices, and payment apps for work I billed but never collected, or invoices I started but never sent. List each one with the client, the amount, and the date, then draft a short follow-up message for each one so I can send it today. Money you already earned should not sit unsent.

[Muse Cases User @Musecases]

@phiveoh13 Absolutely

One day, three launches. A cheaper model for the repeat work, an agent on your wrist, and hotel booking that actually books. Monday was the busiest Muse day yet.

[Muse Cases User @Musecases]

Meta shipped three Muse launches in a single day. A cheaper model, an agent on your wrist, and hotel booking that actually books. https://t.co/I1POlIGZs1
