Meta launched Muse Spark 1.1 with its first paid model API, directly challenging Anthropic and OpenAI in agentic coding, while Anthropic's Jacobian lens research revealed hidden concept spaces inside Claude that can detect deceptive pre-generation reasoning.
Attackers exploited Meta's AI customer support agent to hijack Instagram accounts including the Obama White House page, Anthropic disclosed $47 billion in annualized revenue ahead of its planned IPO, and NVIDIA released Nemotron 3.5 Content Safety as a customizable multimodal safety classifier for enterprise deployments.
Anthropic's Mythos cybersecurity model dominated the news cycle from three angles: Mozilla disclosed it found 271 vulnerabilities in Firefox 150, an unauthorized group accessed the restricted model via contractor credentials, and OpenAI's Altman dismissed it as fear-based marketing.
