Summary

Meta Defends Muse

Meta says Muse Wonder includes its strongest safeguards against chemical, biological, radiological, nuclear and cyber misuse, but report is pending.
Some users claim the assistant accessed personal messages without permission, a charge Meta publicly disputes.

History

Historical Context

In February 2019 OpenAI refused to release the full 1.5-billion-parameter GPT-2 model, citing risks of spam, hate speech, and “infopocalypse” after demonstrating potential misuse. The decision sparked debate, with critics calling the hold “malicious BS” while others warned of AI-generated disinformation. Meta’s 2026 Muse Wonder launch echoes that caution, keeping its weights closed and pledging safeguards, suggesting the 2019 precedent continues to shape AI governance.
