Overview
ChatGPT (powered by GPT-5) is OpenAI’s flagship AI assistant, launched August 7, 2025. It dynamically adapts between quick, concise replies and deep, reasoning-driven analysis depending on the complexity of your request. The system supports text, images, audio, and—in some tiers—video input, enabling richer, multimodal conversations. Key upgrades include “safe completions” for nuanced handling of sensitive topics, multiple conversation personalities, and seamless integration with tools like Gmail and Google Calendar. GPT-5 offers PhD-level performance in coding, writing, mathematical reasoning, and knowledge tasks, making it a versatile tool for creators, professionals, developers, and educators.
Key Features
✦ Dynamic Reasoning: Automatically chooses between fast responses and in-depth thinking for optimal answers.
✦ PhD-Level Performance: Excels in coding, writing, mathematics, health, and research tasks.
✦ Multimodal Capabilities: Works with text, images, audio, and select video inputs.
✦ Safe Completions: Offers helpful, nuanced guidance instead of blunt refusals.
✦ Personalities & Tools: Choose conversational styles and connect with productivity apps.
