OpenAI investigated and patched ChatGPT’s “goblin” obsession, attributing it to reinforcement-learning rewards that over-amplified playful creature metaphors in a nerdy persona that later bled across versions. Major industry moves included xAI’s Grok 4.3 price cuts and voice tools, Mistral’s unified Medium 3.5 model and Work mode, and Anthropic’s managed-agent upgrades alongside a surprise SpaceX compute deal and reports of a much higher Anthropic valuation. Key policy and security developments covered the Musk–OpenAI trial details, Pentagon AI deployments on classified networks, expanded U.S. government pre-release model reviews, and reports of NSA testing Anthropic’s Mythos on Microsoft software.
