ChatGPT
AI Chatbot for Conversation, Writing, and Research
What is ChatGPT?
ChatGPT is OpenAI's general-purpose AI assistant for writing, research, coding, data analysis, image generation, voice, and agentic workflows. The ChatGPT web and mobile apps support multi-turn conversations, file uploads, web search, memory, projects, custom GPTs, apps, deep research, Codex, and image creation depending on plan and region. Current ChatGPT plans center on the GPT-5.5 model family, with Free users receiving limited access and paid plans expanding reasoning, image generation, deep research, agent mode, memory, context, and Codex usage. ChatGPT remains the default consumer AI benchmark because it combines a broad feature surface, frequent model updates, and a large ecosystem of integrations.
Key Features of ChatGPT
GPT-5.5 Model Family
ChatGPT currently centers on the GPT-5.5 model family, with faster everyday modes and higher-reasoning modes depending on plan. Older ChatGPT models such as GPT-4o have been retired from normal ChatGPT use, so plan descriptions should be checked against current OpenAI pricing before purchase.
Files, Data Analysis, and Projects
Upload documents, spreadsheets, images, and code files for analysis. ChatGPT can summarize, extract structure, run data analysis, and keep related work organized through Projects and custom instructions.
Image Generation and Editing
ChatGPT includes image creation and editing directly in the chat experience, with higher limits and faster generation on paid plans. Users can iterate conversationally instead of writing one-off image prompts.
Deep Research and Agent Mode
Paid ChatGPT plans expand access to deep research and agentic workflows that gather information, reason across sources, and complete multi-step tasks with user supervision.
Custom GPTs, Apps, and Memory
Create specialized GPTs, connect supported apps, and let ChatGPT remember preferences where memory is enabled. These features make repeat workflows more personalized and less repetitive.
Codex for Coding Tasks
ChatGPT includes Codex access for software work, with higher included usage on Plus, Pro, and Business plans. Codex can help inspect code, plan changes, and complete programming tasks.
