OpenAI moved on enterprise control, health and account security this week. Google made Gemini 3.5 Flash the default engine in AI Mode worldwide. Monetisation and oversight both tightened across the sector.

What Happened

1. OpenAI Launched Usage Analytics and Spend Controls for ChatGPT Enterprise

On 18 June, OpenAI added a Global Admin Console that tracks ChatGPT and Codex credit use across users, products and models (OpenAI, 2026a). Admins can set workspace limits, group limits and individual overrides (Computerworld, 2026). The release targets cost discipline as enterprise adoption scales.

2. OpenAI Introduced ChatGPT Health

OpenAI released ChatGPT Health, a dedicated experience that brings medical information into the assistant (OpenAI, 2026b). It uses purpose-built encryption and isolation to compartmentalise health conversations (OpenAI, 2026b). The product pushes ChatGPT into regulated, high-trust queries.

3. Google Made Gemini 3.5 Flash the Default in AI Mode

Google set Gemini 3.5 Flash as the default model in AI Mode for users globally (Google, 2026). AI Mode now serves more than one billion monthly users (Google, 2026). Google is folding AI Overviews and AI Mode into one search experience.

4. OpenAI Rolled Out Active Sessions

ChatGPT added Active sessions, letting users review logged-in sessions and sign out of any they do not recognise (OpenAI, 2026c). The feature answers rising concern over account takeover. Security is becoming a search-platform differentiator.

5. OpenAI Expanded Product Feed Ads in ChatGPT

OpenAI opened product feed campaigns in its Ads Manager beta, letting retailers upload catalogues of up to two million items (Marketing4eCommerce, 2026). Ads now attach to high-intent shopping conversations. OpenAI targets $2.5 billion in ad revenue this year (Axios, 2026).

Why It Matters

Control is shifting from the open web to the assistant. OpenAI's enterprise dashboards, health vault and session controls all keep users inside one environment (OpenAI, 2026a). Each feature raises switching costs.

Google answered with scale. One billion AI Mode users and a faster default model concentrate query volume in Gemini (Google, 2026). Publishers lose the click; the platform keeps the answer.

Money follows attention. Product feed ads turn ChatGPT conversations into a storefront (Marketing4eCommerce, 2026). Search economics now run on subscriptions, enterprise credits and native ads at once. To see where your business stands inside AI search today, run your free AI Discoverability Score.
