In-depth review: what ChatGPT (GPT-4o) (chatgpt.com) actually does
Checked 28 Oct 2026ChatGPT (chatgpt.com) is OpenAI's general-purpose assistant. It answers questions, writes and edits files, generates images, runs code and searches the web. The same account works on the web, on iOS and Android, and in desktop apps.
OpenAI sells ChatGPT on six tiers, from a free plan to a $500 Pro plan. Higher plans add frontier models, longer sessions and tools such as deep research and Codex. Business and Enterprise add admin controls and shared workspaces. The product changes often, so the model picker is the best guide to current access. The free tier remains the entry point for most new users.
Features worth knowing
Paid plans can use GPT-6.1 Sol, GPT-6 Astra, GPT-6 Sol and GPT-5.6 Sol Pro. The model picker shows which options your account can access.
Projects keep files and instructions together for repeated work. Scheduled tasks can run prompts on a timetable on Go and higher plans.
Voice mode supports spoken conversations, and Go and higher plans add voice with video. Free users receive a limited number of voice chats.
Deep research produces sourced reports, while Codex writes and runs code. Both have plan-based limits and appear in the tools menu.
What can you do with ChatGPT?
ChatGPT handles text, images, files and code in one conversation. You can upload a spreadsheet, ask for a chart and have Python run the analysis. Files can include documents, spreadsheets and images, which the assistant can summarize or transform. Images can be edited or generated inside the same chat. Voice and video calls are available in the ChatGPT apps. Search and memory let it pull in current information and remember past preferences.
ChatGPT Work and Codex extend this to longer tasks. Work runs on desktop, web and mobile for Plus and above, while Codex focuses on code changes. Pro adds Dots, an always-on agent that can keep working in the background. A shared workspace keeps chats, projects and custom instructions together, and scheduled tasks can run prompts automatically on a chosen daily or weekly timetable.
How much does ChatGPT cost?
Free costs nothing and includes unlimited text chats with GPT-6 plus limited tools. Go is a lower-cost plan with higher tool limits, and it is available in every country where ChatGPT operates. The pricing page shows Go's current price. Plus costs $20 per month, and Pro comes in $100, $200 and $500 tiers.
Business costs $25 per user each month, or $20 on annual billing. Premium Business seats cost $125 monthly, or $100 annually, and remove the five-hour usage limit. Business is self-serve and starts at two users, while Enterprise is sold through sales. Annual billing lowers the effective monthly price for teams that commit to a year.

Plus adds advanced reasoning models, scheduled tasks, custom GPTs and expanded Codex usage; Projects are available on every plan. Pro adds a choice of three usage tiers and expanded access to GPT-6 Astra. It also raises the reasoning context window to 400K tokens. The three tiers differ mainly in included usage and speed.
