ChatGPT is OpenAI's AI assistant for writing, research, images, voice, and coding. It runs on the GPT-6 model family across web, desktop, and mobile, with free and paid tiers.
ChatGPT is OpenAI's AI assistant, and it does far more than answer questions. You use it to draft and edit writing, dig through long documents, generate and edit images, hold a spoken conversation, and write or debug code. It's the assistant most people mean when they say "AI chatbot," and OpenAI says more than 1.2 billion people now use it every week.
The product isn't one model, it's a family. On the current lineup, paid accounts run GPT-6 Sol and free and Go users run GPT-6 Luna, both built for everyday conversation. Plus unlocks advanced reasoning models, and Pro adds Pro reasoning on GPT-6 Astra plus higher usage tiers. You pick a model per task, and the lighter ones keep costs down.
Two things set ChatGPT apart from a plain chat box. First, the interface now adapts to the question: with its Intelligent UI, GPT-6 can build a calculator, a chart, or a small tool right inside the reply instead of returning only text. Second, reach: the same assistant shows up in the browser, the desktop and mobile apps, and the API for developers. The main catch is usage. Free and Go tiers cap uploads, image creation, and voice, and heavy work burns through them fast, which is why daily users often end up on Plus or Pro.
A quick look at ChatGPT's pricing, supported platforms, and performance.
The users, tasks, and scenarios where this tool fits best.
ChatGPT runs on GPT-6, with Sol for paid accounts and Luna for free and Go users. Plus adds advanced reasoning models for harder logic and multi-step work, and Pro unlocks Pro reasoning on GPT-6 Astra. You switch models per task, so a quick summary doesn't carry the same cost as a deep analysis.
Intelligent UI lets GPT-6 choose how to answer. Explain a concept and it can build a clickable diagram, compare options and it lays them side by side, and need a tool and it generates a calculator or a small game inside the chat. OpenAI says this cuts the average wait for a first answer by 44% on web-search questions.
You can generate and edit images, hold a spoken conversation with voice, and, on newer plans, bring in video and screen sharing. File and image uploads let the assistant read documents, spreadsheets, and screenshots, with higher limits as you move up the plans.
Deep research pulls from many sources and returns a structured report, which suits market scans and literature reviews. Data analysis runs code against your spreadsheets to find trends and build charts, and both tools scale up on Plus and Pro.
Projects bundle files, instructions, and context for repeat work. Memory carries useful details across conversations so you repeat yourself less, and custom GPTs let Plus and Pro users build tailored assistants for a specific job.
A desktop app brings ChatGPT to macOS and Windows with shortcuts for work in other apps, including a Work mode for multi-step jobs. For teams, the OpenAI API exposes the same models behind usage-based pricing, so you can build ChatGPT into your own product.
ChatGPT is a general AI assistant for writing, research, analysis, image creation, voice conversation, and coding. People use it to draft documents, question long files, generate images, and hand routine engineering tasks to its Codex agent.

Audiogen is an AI music generator built by Audiogen Inc., a small research team that spent about 2.5 years training its own generative music model and designing a web interface around it. Instead of a plain text box, this AI music tool turns the timeline into a beginner-friendly Generative Audio Workstation, or GAW, where inpainting, extending, remixing and stem editing work more like painting on a canvas. The product is still in beta, so access runs through a waitlist or an invite. Paid plans aren't published yet.
Aiml API is a unified AI model API that puts more than 1000 models from OpenAI, Google, Anthropic, and others behind one endpoint and one bill. You write code against a single OpenAI-compatible schema, then switch between chat, image, video, and audio models by changing a model string. It suits developers and small teams who want multi-model access without juggling a dozen separate provider accounts, and it removes the usual billing headache that comes with testing several vendors. One key covers it all.
