ChatGPT

The most popular universal AI assistant from OpenAI. It is designed to handle both everyday and specialized tasks—from text generation and voice conversations to programming, real-time web search, and step-by-step logical reasoning (Reasoning).

Capabilities and use cases

• Universal content work and multimodality. The GPT-4o model instantly processes text, images, audio, and documents. Advanced Voice mode enables natural voice conversations with emotion and intonation recognition.
• Complex logical tasks and coding (the “o” series: o3, o4-mini). A specialized line of reasoning models focused on the exact sciences (STEM), complex mathematical calculations, code architecture, and in-depth debugging.
• Canvas and interactive development. A dedicated Canvas workspace for convenient collaborative editing of long-form articles and full-scale code development with syntax highlighting and execution.
• Deep search and web research (Deep Research and Search). The built-in search module analyzes up-to-date data online, while the Canvas/Projects feature enables the creation of personal knowledge bases.
