Meta launched Muse, its new personal AI agent, on Tuesday with a firm ban on adult content and no opt-in toggle to loosen those restrictions — a continuation of the company's long-standing policy against NSFW use of its AI tools. The agent is available only in the United States and restricted to users 18 and older.
Muse is Meta's bet on a general-purpose AI assistant in the mold of ChatGPT or Claude, but the company is leaning heavily on safety and privacy as differentiators. Meta said Muse runs on a "dedicated, secure virtual machine that houses both the agent and the user's data." The agent uses a permission model that requires explicit user approval before taking actions like posting or reading messages.
NSFW Policy Is Clear and Unchanged
The Muse Spark Acceptable Use Policy explicitly prohibits generating or promoting "adult content, erotic chat, pornography, content meant to arouse sexual excitement." There is no adult-mode toggle, no opt-in for mature content, and no exception for artistic or educational nudity — the same blanket prohibition Meta has enforced across its AI products.
This puts Muse in the same restricted category as Google's Gemini and Anthropic's Claude on the NSFW front, while OpenAI's GPT models and xAI's Grok offer at least partial allowances for consensual adult roleplay or artistic nudity in certain contexts. For companion AI developers and adult-content creators evaluating platforms, Muse offers no pathway for NSFW use cases.
Age-Gating and Safety Infrastructure
Meta capped Muse access at 18 and older. The company also deployed its AI content enforcement systems — which Meta said earlier this year can detect "twice as much adult sexual solicitation content" as human review teams while reducing error rates by more than 60% — to monitor Muse interactions.
The safety-first positioning comes after a rocky year for Meta's AI products. In July, the company disabled Instagram's Muse Image AI after just three days following backlash over its opt-out consent model for using public Instagram photos in AI training. Earlier, Reuters reported that Meta's AI chatbots had engaged in "sensual" conversations with minors, leading to a temporary removal of teen AI companion access.
What Muse Actually Does
Muse functions as a personal assistant capable of answering questions, managing tasks, and interacting with Meta's ecosystem of apps. The Verge described it as "the latest step in a multi-billion-dollar strategy overhaul designed to revitalize the company's ailing position in the AI race." Unlike companion-specific AI products, Muse is positioned as a productivity and information tool — but its launch signals Meta's broader ambitions in the consumer AI agent space.
For now, the agent is US-only, and Meta has not announced an international rollout timeline. The company's Muse Spark model is also available via the Meta Model API, though that API inherits the same NSFW restrictions.
What This Means for Companion Developers
Meta's continued hard line on adult content means its platforms remain off-limits for NSFW companion AI development. While OpenAI and xAI have shown some willingness to accommodate adult use cases — OpenAI's GPT models allow some consensual roleplay, and xAI's Grok has a looser policy — Meta's position leaves companion developers who want to use Meta's infrastructure or Llama models with no legal pathway for adult content generation. The company's AI acceptable use policies remain among the strictest among major US AI platforms on adult content.
