  "summary": "Anthropic set the tone again, but this snapshot was centred on the fallout from Mythos rather than a clean launch story. Reuters and Axios led with reports that US security bodies were using or reacting to the model despite formal restrictions, while Claude and Opus 4.7 kept the company in the wider product and safety conversation.\n\nAround that, the mood split between commercial momentum and practical workflow experiments. Cursor's reported $2 billion fundraising round, Cerebras's IPO filing, and Sarvam's fresh talks kept investor interest high, while YouTube and Reddit clustered around Codex, Claude Code, local subagents, and the day-to-day question of what AI coding tools are actually good for in real projects.",
