  "summary": "Anthropic supplied the clearest launch signal with Claude Fable 5 and Claude Mythos 5: its official post, Anthropic's launch video, GitHub's Copilot rollout note, Databricks availability and heavy YouTube reaction all pointed to a model aimed at long-horizon coding and knowledge-work tasks. That sat inside a wider agent-tooling day, with Cohere introducing the open-source North Mini Code model, OpenAI showing how Nextdoor engineers use Codex, xAI powering Gopuff's Go shopping agent, and Microsoft recapping Build announcements for startups.\n\nGoogle DeepMind added the strongest learning-and-language thread, publishing guided-learning trial results from Sierra Leone while introducing Gemini 3.5 Live Translate on X. The rest of the snapshot was infrastructure and community reaction: Reuters covered Meta and Reliance's AI data-centre deal, OpenAI's possible Ohio data-centre lease, Anthropic's $35 billion capacity expansion and xAI/SpaceX data-centre litigation, while Reddit focused on Perplexity's leaked system prompt, Codex credits, Copilot agent limits, Claude Code IDE experiments and architecture controls for AI-generated code.",
