Our conclusion.
Pick Gemini when your team works in Gmail, Docs and Sheets, or your work runs on audio and video, because Gemini sits inside Google Workspace on its paid plans and its models read audio and video directly. Pick ChatGPT when your team works in Excel, Word and PowerPoint, or when you need longer replies from the API or the cheapest small model ($0.10 in, $0.50 out per million tokens).
Both make images and both offer voice chat. Gemini also makes short videos on its paid plans, gives the app a 1 million token context window on Google AI Pro against 256,000 on ChatGPT Plus, and has the cheaper entry plan at $4.99 a month against $6.
Through the API, Google's top model costs $2 in and $10 out per million tokens until 30 November 2026, then $4 and $20; OpenAI's costs $10 and $50. OpenAI's smallest model is cheaper than Google's, and OpenAI allows longer replies by default. On consumer plans both use your chats for training unless you turn it off.

For some jobs. Gemini fits a team that works in Gmail, Docs and Sheets, reads audio and video directly, makes short videos and costs less through the API at the top end. ChatGPT fits a team in Excel, Word and PowerPoint, gives longer replies through the API by default and has the cheapest small model. For writing and research, neither company's published results settle it; try both on your own work.
Yes, the Gemini app has a free plan with Flash-Lite, image making and Deep Research. Paid plans run from Google AI Plus at $4.99 a month to Google AI Ultra at $199.99, as of November 2026.
They cost about the same: ChatGPT Plus is $20 a month and Google AI Pro $19.99, which also includes 5 TB of Google storage. The cheapest paid plans are Google AI Plus at $4.99 and ChatGPT Go at $6.
Yes. Google AI Plus adds Gemini in Gmail, and Google AI Pro adds Docs and Sheets. ChatGPT has extensions for Excel, Word, PowerPoint and Google Sheets.
Gemini makes short clips with sound on its paid plans. ChatGPT's plans page lists no video making, and OpenAI closed its Sora video API in September 2026. Both make images.
OpenAI and Google each publish results for their own models, mostly on different tests run their own way, so the numbers do not line up well enough to rank the two. Each company's own model pages give its results.
