ChatGPT
ChatGPT is OpenAI's flagship conversational AI chatbot powered by large language models (GPT-4 and variants). It enables users to engage in natural language conversations with the model, asking questions, generating text, brainstorming ideas, and solving problems across numerous domains. ChatGPT is available as a free service with limited features and as a subscription service (ChatGPT Plus/Pro) offering advanced capabilities, faster response times, and access to new features like Sora video generation and advanced reasoning modes. The service has grown to hundreds of millions of users globally.
Sora
Sora is OpenAI's text-to-video AI model that generates short video clips based on text prompts. Users can create videos up to 1080p resolution and up to 20 seconds in length, or extend and remix existing videos. Sora uses transformer architecture and diffusion model technology to understand and simulate the physical world in motion. Available to ChatGPT Plus and Pro users, Sora includes safety features such as watermarks, red team testing, and safeguards against misuse for generating synthetic media of real individuals.
DALL-E
DALL-E is OpenAI's text-to-image generation model that creates original images based on detailed text descriptions. The model has evolved through multiple iterations (DALL-E 3 being the latest generation) and is integrated into ChatGPT, allowing users to generate, edit, and manipulate images directly within conversations. DALL-E emphasizes photorealistic rendering, stylistic consistency, and accurate text rendering, making it suitable for creative professionals, designers, and content creators seeking rapid visual iteration.
GPT-4 / GPT-5.5
OpenAI's frontier large language models (LLMs) that power ChatGPT and its API offerings. The GPT series represents progressively more capable language understanding models trained on vast amounts of text data. GPT-4 and its variant GPT-5.5 serve as the foundation for conversational AI, code generation, reasoning tasks, and enterprise applications. These models are available through OpenAI's API for developers and via ChatGPT subscription tiers, enabling businesses to build custom AI applications.
