Advanced Account Security in ChatGPT

Explication (en anglais)

OpenAI added an optional Advanced Account Security mode for personal accounts. The practical impact is stronger account protection, but recovery becomes stricter, so users must keep recovery keys and passkeys safe.

Points forts officiels

  • Stronger sign-in options such as passkeys or security keys.
  • Recovery keys, shorter active sessions, login notifications, and session management controls.

Easier model selection in ChatGPT

Explication (en anglais)

ChatGPT made model switching less hidden by moving model selection into the composer flow. This reduces friction when choosing between fast, thinking, and pro-grade models before sending a prompt.

Points forts officiels

  • Model picker moved closer to the composer.
  • Thinking effort controls are exposed directly in the model picker for Thinking and Pro models.

Fast answers in ChatGPT

Explication (en anglais)

OpenAI introduced a faster response path for straightforward information questions. It trades personalization for speed, which is useful for factual lookups but less suitable when memory or prior context matters.

Points forts officiels

  • Common high-confidence questions can return faster answers.
  • Fast answers do not reference past chats or memory and can be disabled in Personalization settings.

Points forts officiels

  • New image generation model in ChatGPT.
  • Images with thinking available on paid plans when using Thinking and Pro models.
