Sophisticated coding capabilities that excel at software development tasks across dozens of programming languages. The standard chat mode provides code generation, debugging, and explanation. Codex, the autonomous software engineering agent available on Plus and Pro plans, handles multi-file projects independently in cloud sandboxes, generating pull requests and running tests automatically.
Generate complete functions or classes for specific requirements, debug problematic code by pasting error messages and stack traces, refactor legacy codebases, and delegate entire feature implementations to Codex for autonomous development with human review.
Comprehensive visual capabilities combining advanced image understanding, DALL-E image generation with precise style and composition control, and Sora short-form video creation. Users can upload images, charts, screenshots, and documents for analysis, while generating new visual content directly within conversations for a seamless creative workflow.
Upload financial charts for trend analysis, generate marketing visuals with specific brand guidelines, create product mockup variations, produce short video clips for social media, and analyze technical diagrams or handwritten notes with accurate text extraction.
Advanced research capability that autonomously investigates topics across multiple web sources, synthesizes findings, and produces comprehensive reports with inline citations. Deep Research browses dozens of pages, cross-references information, and delivers structured analysis in minutes that would take a human researcher hours to compile manually.
Commission thorough competitive analysis, literature reviews, market research reports, technology evaluations, and due diligence summaries. Ideal for professionals who need well-sourced, comprehensive overviews of complex topics without manually searching and reading dozens of articles.
Side-by-side workspace designed for iterative document and code development. Canvas opens a persistent editing panel alongside the chat, allowing users to highlight specific sections, request targeted edits, and refine content collaboratively with AI assistance. Supports both writing and coding workflows with inline suggestions.
Collaborate on business proposals with iterative improvements, develop technical documentation with AI-assisted revisions, refine marketing copy with tone and length adjustments, and pair-program on code with inline AI suggestions and explanations.
Integrated Python environment enabling sophisticated data analysis, visualization, and computation directly within conversations. Users can upload CSV files, Excel spreadsheets, and databases for automated analysis including statistical modeling, chart generation, and data transformation without requiring local development tools.
Analyze sales data for trend identification, create custom visualizations for presentations, run statistical analyses on survey results, clean and transform datasets, and build interactive charts from raw data files uploaded directly into the conversation.
Persistent memory architecture that retains user preferences, project context, communication styles, and important details across conversations. Memory builds a personalized profile over time, allowing ChatGPT to provide increasingly relevant and tailored responses without requiring users to repeat context in every new conversation.
Build long-term projects with retained context across multiple sessions, reference previous analyses without re-uploading data, maintain consistent writing style preferences, and receive recommendations tailored to your role, industry, and past interactions.
Comprehensive business-grade security features including SAML single sign-on, SCIM user provisioning, granular admin controls, audit logs, and data residency options. Business and Enterprise plans guarantee that conversations are never used for model training, with centralized billing, usage analytics, and dedicated account management for large deployments.
Deploy across large organizations with centralized user management, maintain compliance with industry regulations through audit trails and data residency controls, manage team access and permissions through admin consoles, and monitor usage patterns across departments.
ChatGPT offers six pricing tiers: Free ($0) with GPT-4o access and basic features, Go ($8/month) with expanded limits in select regions, Plus ($20/month) with full access to reasoning models and Codex, Pro ($200/month) with unlimited usage and exclusive o3-pro model, Business ($25/user/month) with team workspaces and admin tools, and Enterprise (custom pricing) with advanced security, compliance, and dedicated support.
As of early 2026, ChatGPT offers access to GPT-4o as the flagship multimodal model for everyday tasks, o3 and o4-mini as dedicated reasoning models for complex logic and math problems, and the exclusive o3-pro model available only on the Pro plan for maximum reasoning depth. The free tier includes GPT-4o with usage limits, while paid plans unlock higher limits and full reasoning model access.
ChatGPT offers the most comprehensive integrated feature set including autonomous coding (Codex), image generation (DALL-E), video creation (Sora), and deep research in a single platform. Claude excels at nuanced writing, longer context handling, and careful instruction following. Gemini integrates deeply with Google Workspace. Perplexity specializes in cited web research. ChatGPT's advantage is breadth — no single competitor matches its range of built-in capabilities.
ChatGPT excels at coding assistance across multiple programming languages including Python, JavaScript, TypeScript, Java, C++, and more. The standard chat mode helps with code generation, debugging, and explanation. Codex, available on Plus and Pro plans, goes further by handling multi-file coding tasks autonomously in a cloud sandbox — it can build features, fix bugs, write tests, and generate pull requests with minimal human oversight.
Yes, all ChatGPT plans include real-time web browsing capabilities. ChatGPT can search the web, read current articles, check live data, and provide up-to-date information on recent events, prices, and news. However, web browsing can occasionally fail to load pages or return cached results, so it is best to verify time-sensitive information from the original sources when accuracy is critical.
Yes, ChatGPT includes sophisticated memory features that retain user preferences, project context, and communication styles across conversations. Memory can be managed in Settings where users can view, edit, or delete specific memories. This feature allows ChatGPT to provide increasingly personalized responses over time, remembering details like your role, preferred writing style, and ongoing projects without requiring repeated explanation.
Yes, ChatGPT offers full-featured mobile applications for iOS and Android with complete feature parity to the desktop experience. Mobile apps include voice interaction for hands-free conversations, camera integration for image analysis, file uploads, access to all models and features included in your plan, and support for Custom GPTs. The desktop app for macOS and Windows adds Model Context Protocol (MCP) integration for connecting to local tools.
Data privacy varies by plan. Free, Go, Plus, and Pro plans may use conversations for model training by default, but users can opt out in Settings under Data Controls. Business and Enterprise plans never use conversations for training and include additional security features like SSO, admin controls, and audit logs. Enterprise adds SAML authentication, SCIM provisioning, and data residency options for organizations with strict compliance requirements.
Custom GPTs are specialized AI assistants you can create for specific tasks, industries, or workflows without any coding. Use the GPT Builder to define instructions, upload reference documents, and configure capabilities like web browsing and code execution. Custom GPTs can be kept private, shared with specific people, or published to the GPT Store. Over 3 million Custom GPTs have been created, covering use cases from customer support to data analysis to creative writing.
Canvas mode provides a side-by-side workspace where ChatGPT and the user can collaboratively edit documents and code in real time. Instead of generating content in the chat thread, Canvas opens a persistent editing panel where you can highlight text, request specific changes, and iterate on content with AI-powered suggestions. It supports both writing and coding workflows, with features like inline comments, version tracking, and the ability to adjust tone, length, and reading level for written content.
Now that you know how to use ChatGPT, it's time to put this knowledge into practice.
