  "summary": "Anthropic still dominated this snapshot, with Claude Design driving a fresh wave of demos, walkthroughs, and community experiments across YouTube and Reddit while Mythos kept the company in the policy and cybersecurity headlines. The centre of gravity was practical use: design tooling, Claude Code setups, Copilot CLI experiments, and agent-style workflows rather than abstract model chatter.\n\nAround that, the news cycle split between funding and adoption pressure. Cursor's reported $50B fundraising talks and Cerebras's IPO filing kept investor attention high, OpenAI's GPT-5.4-Cyber widened the security race, and a run of consumer stories on AI fatigue, workplace pressure, and therapy apps suggested the public mood is becoming more conflicted even as the tooling improves.",
