Lavkush ChatGPT is OpenAI's AI assistant, the product that started the modern AI chat era when it launched in November 2022. You type a question or a task in plain language, and ChatGPT answers, writes, explains, summarises, translates, brainstorms and codes with you in a conversation. It now runs on the GPT-6 model family and has grown far beyond a chat box, with research tools, an agent mode, image generation, voice conversations and serious coding help. For hundreds of millions of people, ChatGPT is simply what "AI" means, and it is still the assistant most rivals are compared against.
A Very Short History
When ChatGPT appeared in November 2022, it reached 100 million users faster than any consumer product before it. Offices, classrooms and group chats all changed within a few months. OpenAI has kept up a brisk pace of upgrades since then: better models, memory, voice, images, tools and team plans followed one after another. You can meet the current version at chatgpt.com, and the shape of the product today is best understood through its models and plans.
The Current Models: the GPT-6 Family
ChatGPT now runs on the GPT-6 family, and which model you get depends on your plan:
- GPT-6 Luna is the fast default on the Free and Go plans. From August 2026, OpenAI rolled out uncapped text chats on this tier, which removed the old frustration of hitting a wall mid-conversation.
- GPT-6.1 Sol became the default model in Chat for Plus subscribers on 7 October 2026, a step up in reasoning and quality for paying users.
- GPT-6 Astra, released on 3 September 2026, is the most capable model in the family and is reserved for the higher tiers, for the hardest reasoning, research and coding work.
The practical lesson: the free ChatGPT of today is far stronger than the paid ChatGPT of a few years ago, but the newest flagship still lives behind the paid plans.
What Can ChatGPT Do?
The feature list is long, so here are the ones people actually use every week:
- Deep Research sends ChatGPT to read many sources and return a structured, cited report.
- Agent mode lets ChatGPT carry out multi-step tasks with tools, asking you at the important checkpoints.
- Custom GPTs are tailored versions of ChatGPT built for one job, like a strict proofreader or a patient maths tutor.
- Canvas-style editing puts your document or code beside the chat so you can refine it together, line by line.
- Voice mode turns the chat into a natural spoken conversation, handy for language practice and hands-free questions.
- Image generation, file analysis and memory cover pictures, spreadsheets and documents, plus remembering your preferences across chats.
- Codex is OpenAI's coding agent for software work, from fixing bugs to building features.
Coders were early adopters, and they still are. If you write code, our practical guide on how to use ChatGPT for coding is the natural next read, and our head-to-head on GitHub Copilot vs ChatGPT for coding explains when an editor assistant beats a chat window. One small housekeeping note for readers: OpenAI's Sora video app was discontinued in April 2026, so if an old tutorial mentions it, that product no longer exists.
ChatGPT Plans and Prices
ChatGPT has more tiers than it used to, which confuses everyone, so here they are in one place. Model names and plan details change often, so treat this as a map and confirm the final numbers on the official ChatGPT pricing page:
| Plan | Price | What you get |
|---|---|---|
| Free | $0 | GPT-6 Luna with uncapped text chats; ads in some markets |
| Go | $8/month | Higher limits and more features for regular light users |
| Plus | $20/month | The full tool suite: Deep Research, agent mode, projects, tasks, custom GPTs and more Codex usage |
| Pro | $100 and $200/month tiers | GPT-6 Astra and the highest limits for professionals |
| Pro 500 | $500/month | The top tier, added on 29 September 2026, for extreme workloads |
| Business and Enterprise | Custom | Team workspaces, admin controls and organisation-grade security |
For most individuals, Plus at $20 remains the sweet spot: it unlocks the tools that make ChatGPT feel like a different product from the free version. The Pro tiers are for people who run the assistant all day, every day, and can do the maths on what their time is worth. Business and Enterprise plans sit outside this ladder entirely, priced per organisation, with shared workspaces, stronger privacy controls and central billing for teams.
How People Actually Use ChatGPT Day to Day
The marketing pages list features, but real usage is messier and more interesting. A typical Plus subscriber's week might look like this. Monday starts with Deep Research comparing three tools for a report, citations included. Tuesday, a spreadsheet gets uploaded and questioned like a junior analyst: which region grew, which product slipped, what changed in March. Wednesday is writing day, with Canvas open beside a proposal that gets tightened paragraph by paragraph. On Thursday, agent mode handles a dull multi-step chore, like gathering prices from a list of suppliers into a table. Friday ends with voice mode on a walk, talking through ideas for next week while the dog pretends not to listen.
Notice what is missing from that week: almost no one opens ChatGPT just to "chat" any more. The product quietly turned into a workbench. Memory means it knows your projects and preferences, custom GPTs mean the proofreader already knows your style guide, and projects keep each job's files in one place. The free tier still answers questions perfectly well, but the paid experience is about continuity: the assistant remembers the plot.
There is a learning curve, though a gentle one. Good results follow good instructions. Tell ChatGPT who the audience is, what good looks like and what to avoid, and the output jumps a level. Vague questions get vague answers, which is less a flaw of the model and more a mirror held up to the prompt.
Who Is ChatGPT Best For?
ChatGPT's strength is breadth. Students use it to understand topics, professionals to draft and summarise, developers to code, marketers to brainstorm, and curious people to answer everything from recipe swaps to visa rules. Because it does so much in one place, it is the easiest single recommendation for a beginner: one account covers writing, research, images, voice and code. Specialists may prefer a rival for one specific job, and our other guides in this series cover those. But as the default, all-purpose assistant, ChatGPT earned its crown and, so far, keeps it.
Frequently Asked Questions
Is ChatGPT free?
Yes. The Free plan costs $0 and runs GPT-6 Luna with uncapped text chats, though some markets see ads. Paid plans add stronger models and the full tool suite.
How much is ChatGPT Plus?
Plus costs $20 per month. Go is $8 per month, and Pro tiers run at $100, $200 and $500 per month for the heaviest users.
What is the newest ChatGPT model?
The GPT-6 family powers ChatGPT now. GPT-6 Astra is the most capable, GPT-6.1 Sol is the Plus default, and GPT-6 Luna is the fast default on Free and Go.
Can ChatGPT write code?
Yes, very well. It explains, writes and debugs code in the chat, and OpenAI's Codex agent handles larger software tasks on paid plans.
What happened to Sora?
OpenAI discontinued the Sora video app in April 2026. ChatGPT itself continues as the main consumer product.
Conclusion
ChatGPT started the AI conversation era in 2022 and has stayed at the centre of it by doing nearly everything reasonably well, in one friendly window. The GPT-6 family and the wider plan ladder mean there is now a version for the curious, the professional and the truly obsessed. Start free, learn what you actually use, and upgrade only when a limit genuinely gets in your way. That order of operations saves money and teaches you the tool at the same time.
