ChatGPT is a conversational AI assistant from OpenAI that has transformed the way humans interact with artificial intelligence. Launched on November 30, 2022, the tool has gathered an audience of over 200 million active users weekly in just a year and a half. The model understands natural language and works with text, code, images, documents, and voice in a unified interface-from writing articles to debugging complex algorithms.
In 2026, ChatGPT represents a whole ecosystem: basic models GPT-4o and GPT-4o mini for everyday tasks, specialized o1 series for deep reasoning, integrated image generation through DALL-E, Canvas mode for collaborative work on texts and code. The tool is available via web, mobile apps, and API for integration into your own products.
Key Features of ChatGPT
- Conversational interface with natural language - the model remembers the dialogue context within a session, answers follow-up questions without needing repeated explanations, and conducts multi-step conversations like a live expert.
- Code generation and editing - supports dozens of programming languages from Python to Rust, debug existing code, explain complex sections, refactor, and manage large codebases.
- Multimodality - a unified interface for working with text, images, PDFs, Excel files, and voice. Upload documents and ask questions about their content, analyze graphs in screenshots, or communicate via voice in real-time.
- Advanced reasoning mode o1 - specialized models perform a deep chain of logical steps before responding. Ideal for mathematics, scientific tasks, and multi-step problems where accuracy is critical.
- Working with documents and spreadsheets - direct integration with Excel and Google Sheets allows building formulas, creating summary reports, and analyzing data through a simple chat. Upload large documents up to 1 million tokens on the Pro plan.
- Internet search - the model searches for information in real-time, fact-checks, finds the latest news and statistics, formulates sub-queries, and synthesizes answers from multiple sources.
- Image generation via DALL-E - create visual content based on text descriptions directly in the chat: illustrations, infographics, concept art, or edit existing images.
- Custom GPTs - create personalized versions of ChatGPT for specific tasks without programming. Customize tone, style, upload a knowledge base, and publish the result in GPT Store.

Comparison with Competitors
ChatGPT remains the leader in versatility and product maturity, but competition is intensifying. Claude from Anthropic focuses on response safety and ethics, has a larger context up to 200K tokens on basic plans versus 128K for GPT-4, and handles long documents better. However, ChatGPT is stronger in coding, multimodality, and has a more developed ecosystem with GPT Store and numerous integrations.
Gemini from Google offers native integration with Gmail, Docs, and Drive, free access to advanced features, and strong multilingual capabilities. ChatGPT outperforms in logical reasoning quality-especially the o1 series-and has a more mature product with a refined user experience. Grok from xAI Elon Musk has access to real-time Twitter/X data and a more provocative style but lags significantly in versatility and accuracy.
DeepSeek - a Chinese open-source model - shows competitive results in mathematics and coding with significantly lower training costs. ChatGPT maintains an advantage in product polish, multimodality, and a developed ecosystem of partner integrations.

Getting Started with ChatGPT
-
1Connect VPN - the official site chat.openai.com is blocked from Russian IP addresses. Use a reliable VPN service with servers in the USA or Europe.
-
2Create an account - register via email, Google, or Microsoft. The process takes less than a minute. Confirm your email for activation.
-
3Choose a plan - start with a free plan to get acquainted with basic features. For professional use, consider Plus at $20/month.
-
4Start a conversation - describe your task as specifically as possible, specify the desired response format and details. Clarify and adjust the result during the conversation.
Integrations and Ecosystem
ChatGPT integrates with Microsoft Office (Excel, Word, PowerPoint), Apple Intelligence, Slack, Zapier, and Make for automating workflows. GPT Store contains thousands of custom GPTs for specific tasks-from SEO optimization to legal analysis. An API for developers allows embedding ChatGPT capabilities into your own products with flexible generation parameter settings and function calling to invoke external tools.
Frequently Asked Questions
Is ChatGPT free?
Yes, the basic Free plan offers unlimited access to GPT-4o mini with a limited number of queries to GPT-4o. Advanced features require a Plus subscription starting at $20/month.
How to use ChatGPT in Russia?
A VPN with servers outside of Russia is required. Payment can be made via foreign cards or aggregators like Study AI with Russian payment methods.
How is ChatGPT different from other AI chatbots?
Versatility-from texts to code, multimodality, deep reasoning mode o1, developed ecosystem with GPT Store, and the best voice interface on the market.
Is it safe to upload documents to ChatGPT?
OpenAI claims encryption of data and disabling learning on user's content. However, uploading strictly confidential documents is not recommended-use corporate solutions with additional guarantees.
