Weekly briefing — AI search and research tools, 29 Apr – 6 May

1. ChatGPT Deep Research extended to 30-minute runs with export (OpenAI release notes, 2 May) — Why: your "research faster" lesson shows a 5-minute run; the screenshots are stale. Do: re-capture by Friday.
2. Perplexity Spaces adds shared instructions for teams (Perplexity blog, 30 Apr) — Why: your team-research module assumes personal Spaces. Do: a one-paragraph update.
3. Google AI Mode expands to 12 countries incl. DE and ES (Google blog, 1 May) — Why: 40% of your traffic is DE/ES; organic click-through will move. Do: watch Search Console for two weeks.
4. Anthropic raises Claude file limits (Anthropic docs, 3 May) — Why: your "upload 400 pages" lesson can cite a bigger number. Do: nothing yet.
5. Perplexity reported raising at $18B (The Information, 5 May) — unverified, single source — affects nothing you ship.

Safe to ignore: the "AI search is dead" essay — opinion, no data.
Quiet item: AI Mode ad formats mentioned in a Google developer note (4 May) — if ads enter AI answers, your CAC assumptions change in Q3.
