ChatGPT 5 (GPT-5) is now the default model on the web and mobile apps—free to start using right after you sign in. On the free plan you get full GPT-5 access until a daily cap (≈30 messages/day), after which chats seamlessly continue on GPT-5 Mini so you can keep working without interruption. GPT-5 introduces a unified architecture that automatically adjusts its reasoning depth: it answers quick requests fast and engages deeper reasoning for complex tasks. Paid users can enable Thinking Mode for extended, multi-step reasoning. In creator tests, GPT-5 generated a working cookie-themed Tetris game (HTML/CSS/JS), even extracting brand colors from a provided logo. Beyond the core model, ChatGPT adds native Gmail and Google Calendar connectors (rolling out to Pro first), personality and chat-color customization, an upgraded Advanced Voice Mode for natural conversations, and a Study & Learn mode that guides you step-by-step to master new skills—from coding to baking. This structured summary covers what’s new, how to start, practical use cases, and safety tips so teams and beginners can adopt GPT-5 quickly and confidently.
