OpenAI Launches GPT-5 with Major ChatGPT Updates

OpenAI has unveiled GPT-5, its latest AI model, alongside significant upgrades to ChatGPT. The update eliminates the model picker for most users, introducing an auto-switching system that defaults to GPT-5 for a streamlined experience. Subscribers to ChatGPT Plus, Pro, and Team tiers retain access to specialized variants like GPT-5 Thinking and GPT-Thinking Pro.

Four new personality modes—Cynic, Robot, Listener, and Nerd—offer tailored interactions. Enhanced coding capabilities now allow users to build interactive applications through simple prompts. A refined voice mode improves instruction parsing and supports custom GPT integrations.

Pro users gain upcoming Google service integrations, enabling automated data pulls from Gmail and Calendar. OpenAI retired legacy models including GPT-4o and GPT-4.5, citing GPT-5's superior accuracy and reduced hallucination rates. Free users now access advanced reasoning features previously reserved for paid tiers.
