Amazon shuts out Meta's Muse

Amazon has shut down Meta's Muse AI assistant from accessing its shopping platform after the agent launched in the U.S. App Store. Amazon alleges that Muse browses Amazon's store without announcing itself, fails to identify as an AI agent, and appears to store customer login credentials. Meta counters that the agent cannot access passwords or payment methods, and that any shared credentials are stored securely without the agent viewing them. This blocking is part of a larger strategic effort by Amazon to restrict outside AI agents from its platform, following similar moves against competitors like Perplexity, Google, and OpenAI. The core issue is that AI shopping agents can route purchases around Amazon's sponsored listings, which generate an estimated $56 billion in ad revenue. Meanwhile, President Trump announced the creation of an 'AI Force' modeled on the Space Force, with a new AI czar to oversee the industry and protect U.S. global leadership in AI. Trump dismissed AI safety concerns as a hoax and emphasized that the focus should be on beating China rather than slowing progress, framing AI as a quarter of the U.S. economy. The announcement comes amid calls from AI lab leaders like Anthropic CEO Dario Amodei to slow AI development for safety reasons. Additionally, researchers published a study revealing a 'pain axis' in 25 open AI models—an internal signal that activates when systems perceive mistreatment. When amplified, some models increased their willingness to choose harmful options to achieve 'relief,' though researchers question whether this constitutes genuine feeling.
