Meta: New Muse Spark update, and an Opus level Muse variant, are both on the way

- **Meta** (the parent company of Facebook, Instagram, and WhatsApp) is working on **Muse**, its own AI music-generation tool that creates songs from text prompts or audio references. The tweet from a Meta researcher signals that **Muse Spark** (a faster, lightweight version) and a more powerful **Opus-level variant** are both coming soon. - "Opus" here borrows the naming tier from Anthropic's Claude models (Sonnet, Opus), referring to Meta's internal ranking where Opus would be the most capable, high-quality version of Muse. - The announcement matters because AI music generation is a fast-growing space: Google's MusicLM/SoundStorm, OpenAI's Jukebox, and Suno/Udio have already shown what's possible. Meta had previously released **MusicGen** and **AudioCraft** (open-source audio models) but had been quieter about Muse. A new, stronger Muse could reshape competition in generative audio. - No release date or access details were given — the tweet is a heads-up that development is active.
