## Summary

Meta has announced Muse Spark, a closed‑weight multimodal reasoning model, as its new flagship AI. The first public release is version 1.3, which can analyze text and images, use tools, and run sub‑agents. The model is available through an API and is priced at $1.25 per million input tokens and $4.25 per million output tokens, with a discounted Contributor tier.

Muse Code is a terminal‑based coding agent that uses Muse Spark and offers a $5/month tier, cheaper than Claude’s $20/month plan. The personal‑assistant app Muse runs on a virtual Linux VM and can browse the web, make purchases, and interact with third‑party apps, but has raised security concerns. Meta also announced Muse Charm, a voice‑controlled physical AI device.

The shift follows Llama 4’s underperformance against Chinese open models and Meta’s reorganization into Meta Superintelligence Labs. The company is moving away from open‑source models toward proprietary offerings, a change that may alter the competitive landscape for developers and enterprises.

## Key points

- Meta’s flagship model Muse Spark is a closed‑weight multimodal reasoning model released as version 1.3.
- Muse Code offers a $5/month tier for a terminal‑based coding agent using Muse Spark, priced lower than Claude.

## Why it matters

Meta’s pivot to proprietary multimodal models signals a shift in the AI ecosystem, affecting open‑source competition and the availability of powerful tools for developers and enterprises.
