ChatGPT

ChatGPT is a chat-based AI assistant built on successive GPT model generations, fine‑tuned via reinforcement learning with human feedback (RLHF) for dialogue-optimized responses. It handles tasks such as brainstorming, writing, planning, coding, translating, and summarizing using natural language understanding and contextual memory within conversations.

The platform integrates tool-based enhancements like web search, image and file analysis, deep research, voice interaction, scheduled tasks, and custom GPTs—expanding from simple chat to a multi-modal assistant for complex workflows.

• Web Browsing & Source Citing: Enables live web search within conversations, delivering up-to-date, cited information—crucial for current-event research.
• Deep Research Agent: Performs multi-step synthesis across online sources, ideal for strategy, reports, and literature consolidation.
• Image & File Handling: Supports image inputs and file uploads (e.g., PDFs), allowing content extraction, summarization, and visual interpretation.
• Custom GPTs & Projects: Users can build personalized assistants with defined behavior, files, and tool access. Projects help organize multi-session workflows.
• Scheduled Tasks & Voice Mode: Automate future actions like reminders or updates. Voice mode includes advanced capabilities like video and screen-sharing in higher plans.

• Content Creators & Writers: Use natural-language generation, summarization, and brainstorming across long-form and creative content.
• Analysts & Researchers: Leverage deep research, web browsing, and data analysis to compile structured insights from multiple sources.
• Developers & Coders: Utilize file/code analysis and Codex integration (in Work mode) to review and refactor codebases efficiently.
• Business Teams & Administrators: Team and Enterprise plans offer secure workspaces, admin controls, compliance, and internal data connectors for company-wide workflows.

• Account Setup: Visit chatgpt.com or OpenAI, log in or sign up, access via web or mobile apps.
• Choose Subscription Tier: Select Free, Go, Plus, Pro, Business, or Enterprise depending on needs.
• Initiate Chat: Begin a conversation—ChatGPT understands follow-up queries and retains context.
• Use Tools: Engage enhanced tools like web search, file/image upload, voice mode, scheduled tasks, and Projects per plan access.
• Manage Materials: Organize chat history, Projects, and Custom GPTs; manage memory and exports in settings.
• Automation & Advanced Use: In higher tiers, schedule tasks, build multi-step workflows, and integrate Codex and internal connectors.

OpenAI structures ChatGPT with tiered, per-user or per-workspace subscription models.

• Free Plan: Basic access to GPT‑4.1 mini, limited tools, voice, image, memory, and uploads.
• Go: Mid-tier with expanded access to GPT‑5.5 Instant, more messages, uploads, image creation, memory. May include ads.
• Plus: Includes advanced reasoning models (e.g., GPT‑5.6), deeper tool access such as Projects, Scheduled Tasks, Custom GPTs. Usage-based billing.
• Pro: Highest individual tier—maximum usage, reasoning power, deep research, image/video generation, first access to new tools. Subject to abuse guardrails.
• Business & Enterprise: Team-based secure workspaces, admin controls, compliance features, internal connectors. Per-user seat-based billing; Enterprise includes extended context, SLAs, priority support.
• Usage of Codex or agentic tools may be credit- or token-based billing depending on plan.
