ChatGPT
The most popular AI chatbot by OpenAI, powering conversations for over 200 million weekly users
ChatGPT is the AI assistant that brought generative AI into the mainstream. Built by OpenAI and powered by the GPT-4o multimodal model, it handles everything from writing and coding to image generation, data analysis, and real-time web search. Whether you need to draft an email, debug a Python script, or analyze a spreadsheet, ChatGPT is the general-purpose AI tool that most people reach for first.

ChatGPT is an AI chatbot developed by OpenAI, the San Francisco-based research company that also created GPT-4, DALL-E, and Whisper. First launched in November 2022 using the GPT-3.5 model, it quickly became the fastest-growing consumer application in history, reaching 100 million users within two months. Today, ChatGPT runs on GPT-4o, OpenAI's most capable multimodal model, and serves over 200 million weekly active users across web, mobile, and desktop applications.
What sets ChatGPT apart from earlier AI systems is its conversational interface and breadth of capability. GPT-4o — the "o" stands for "omni" — processes text, images, audio, and documents natively in a single model. This means you can paste a photo of a restaurant menu and ask ChatGPT to translate it, upload a CSV file for instant data analysis, or have a real-time voice conversation that feels remarkably natural. The model retains context across a conversation, so you can refine your requests iteratively rather than starting over each time.
Beyond basic chat, ChatGPT includes several built-in tools that extend its capabilities significantly. The Code Interpreter (also called Advanced Data Analysis) runs Python in a sandboxed environment, allowing you to process data, create visualizations, and manipulate files without leaving the conversation. DALL-E integration lets you generate and edit images from text descriptions. Web browsing retrieves real-time information from the internet. And Custom GPTs let you build specialized versions of ChatGPT — complete with custom instructions, knowledge files, and API connections — without writing a single line of code.
OpenAI offers ChatGPT across multiple tiers. The free plan gives access to GPT-4o mini and limited GPT-4o usage, which is enough for casual use. The Plus plan at $20 per month unlocks full GPT-4o access, higher message limits, DALL-E, Advanced Data Analysis, and priority during peak times. The Team plan at $25 per user per month adds workspace collaboration, an admin console, and data exclusion from training by default. Enterprise pricing is custom and includes SSO, audit logs, unlimited access, and dedicated support.
Key Features
Multi-Modal Understanding
GPT-4o processes text, images, audio, and documents natively. Upload a photo, paste a PDF, or speak aloud — ChatGPT understands all input types in a single conversation thread.
Code Interpreter
Run Python code in a sandboxed environment right inside the chat. Upload CSVs, create charts, perform statistical analysis, and convert file formats without leaving the conversation.
DALL-E Integration
Generate and edit images from text descriptions using DALL-E 3. Create marketing visuals, concept art, diagrams, and illustrations directly within ChatGPT.
Custom GPTs
Build specialized ChatGPT versions without code. Add custom instructions, upload knowledge files, connect APIs, and share through the GPT Store for others to use.
Web Browsing
Search the internet and retrieve real-time information from live websites. Get current news, stock prices, weather, research papers, and other time-sensitive data with source citations.
File Analysis
Upload PDFs, Word documents, Excel spreadsheets, and images for instant analysis. ChatGPT can summarize reports, extract data from tables, compare documents, and answer questions about uploaded content.
Pricing
ChatGPT offers a generous free tier alongside several paid plans. The Plus plan is the sweet spot for individual power users, while Team and Enterprise add collaboration and security features for organizations.
| Plan | Price | Best For | Details |
|---|---|---|---|
| Free | $0 | Casual users | GPT-4o mini, limited GPT-4o, basic web browsing |
| Plus | $20/mo | Power users | Full GPT-4o, DALL-E, code interpreter, higher limits, priority access |
| Team | $25/user/mo | Small teams | Everything in Plus, admin console, workspace management, data excluded from training |
| Enterprise | Custom | Organizations | Unlimited usage, SSO, audit logs, dedicated support, custom data retention |

Frequently Asked Questions
What is ChatGPT?
ChatGPT is an AI chatbot created by OpenAI, first launched in November 2022 and now powered by the GPT-4o multimodal model. It can understand and generate text, analyze images, run Python code, browse the internet, generate images with DALL-E, and hold real-time voice conversations. With over 200 million weekly active users, it is the most widely used AI assistant in the world, available on web, iOS, Android, macOS, and Windows.
Is ChatGPT free to use?
Yes, ChatGPT offers a free tier that includes access to GPT-4o mini and limited GPT-4o usage. This is sufficient for casual tasks like writing emails, answering questions, and basic coding help. The Plus plan at $20 per month unlocks full GPT-4o access with higher message limits, DALL-E image generation, Code Interpreter for data analysis, and priority access during peak hours. Team ($25/user/mo) and Enterprise (custom) plans add collaboration and security features.
What is GPT-4o?
GPT-4o is OpenAI's flagship multimodal model — the "o" stands for "omni." Unlike earlier GPT-4 versions that routed different input types to separate models, GPT-4o natively processes text, images, audio, and documents in a single model. This makes it faster, more consistent, and more cost-efficient. It powers ChatGPT's voice mode, vision capabilities, and real-time reasoning, matching or exceeding GPT-4 Turbo on most benchmarks while being significantly cheaper to operate.
What are Custom GPTs?
Custom GPTs are specialized versions of ChatGPT that anyone can build without coding. You give your GPT a name, custom instructions, knowledge files (like PDFs or documents), and optionally connect it to external APIs. Businesses use them for customer support bots, internal knowledge bases, and domain-specific research assistants. Custom GPTs can be shared privately, within an organization, or publicly through the GPT Store. Available on Plus, Team, and Enterprise plans.
Can ChatGPT browse the internet?
Yes. ChatGPT's web browsing tool searches the internet and retrieves up-to-date information from live websites. This lets it answer questions about current events, recent research, live prices, sports scores, and other information beyond its training data. When browsing, ChatGPT includes source links so you can verify the information. Web browsing is available with limited usage on the free plan and full access on Plus, Team, and Enterprise plans.
What are the best alternatives to ChatGPT?
The strongest ChatGPT alternatives in 2026 are Claude by Anthropic, known for a 200K token context window, careful reasoning, and strong safety practices; Google Gemini, tightly integrated with Google Workspace and Search; Perplexity, optimized for research with real-time citations for every claim; and Poe by Quora, which aggregates GPT-4o, Claude, Gemini, and other models into a single subscription. The best choice depends on whether you prioritize depth of reasoning, research accuracy, ecosystem integration, or model variety.
