Anthropic folds Cowork into Claude chat and launches Docs/Slides; OpenAI opens ChatGPT to paid business placements, both same-day moves

What happened

Anthropic merged Claude's standard chat interface, Cowork (its agentic/background-work mode) and Artifacts into one unified product ("one Claude") and launched beta Claude Docs and Claude Slides, so the product itself now decides whether a request needs a quick answer, a document, a slide deck or a longer agentic run rather than making the user pick a tab. Docs/Slides export to Word, Google Docs, PowerPoint and PDF; rollout starts with Pro/Max subscribers on web, desktop and mobile "over the coming weeks," with Team/Free and Enterprise (30 days' notice) to follow. Published ~12:30pm ET 09-16. (TechCrunch, Fortune)
OpenAI formally introduced "Sponsored Agents" in ChatGPT — brand-paid AI agents a user can opt into after clicking a labeled ad, which then complete a real task (like booking a service) rather than just serving a link — with Wayfair and Angi as launch advertisers, HubSpot as first CRM partner and Shopify as first e-commerce partner. Angi co-founder Angie Hicks: "homeowners can go directly from discussing a home project in ChatGPT to connecting with a skilled local pro." Published ~9:00am ET 09-16. This is OpenAI's advertising business taking agent form rather than banner form — read alongside OpenAI IPO's revenue-growth figures. (GlobeNewswire — Angi)

Credibility ratings combine two public datasets: Lin et al. 2023, PNAS Nexus 2(9):pgad286 (CC BY 4.0) for the domain-quality score, and Wikipedia's perennial-sources list (CC BY-SA 4.0) for the reliability tier. A rating describes an outlet's general record, never this particular article. Unrated means absent from those datasets — not a judgement.
