Top developments
ChatGPT Outage and Service Instability
On October 28, 2026, users reported widespread failures with ChatGPT, including slow responses and failed logins. This incident follows a string of recent disruptions affecting OpenAI services, including Codex and developer tools, over the past week. The instability comes as OpenAI faces increasing pressure from competitors offering more reliable uptime and competitive pricing.
Privacy Retention Policies Diverge
A new comparison of privacy defaults reveals stark differences in data retention policies among major assistants. Copilot, ChatGPT, Claude, and Gemini vary significantly in how long they retain user data, with ranges from 30 days to 5 years depending on the service and user settings. Experts advise users to actively change these default settings to minimize data exposure.
No Sign-Up Access Expanded
In a test conducted on October 27, 2026, ChatGPT, Gemini, and Perplexity were found to answer queries without requiring user sign-up. This trend of "logged-out" access is becoming a key feature for casual users, though it often comes with stricter usage limits compared to paid accounts.

Context & numbers
Market Share and User Growth
While ChatGPT leads with approximately 1.2 billion weekly active users, its share of unique AI assistant users fell below 50% for the first time in March 2026, as Gemini and Claude grew.

Anthropic’s Claude Sonnet 5.5 is priced at $2/$10 per million tokens, and Haiku 5.5 at $0.10/$0.50. Consumer plans range from 4.99 euros for Google AI Plus to 20 dollars for Claude Pro.
