  2. Google opens a new AI model. Google has released a new AI model called Gemini 4 Carbon. Developers, companies, scientists and everyday users can all try it, Google says.
  3. First, a quick look at model types. AI models come in several levels for different uses, like tools of different sizes in a toolbox. Google recently released Gemini 4 Argon (an earlier model) first. Google says Argon suits most coding and knowledge work.
  4. It digs deeper into harder tasks. Carbon is made for hard jobs, like multi-step coding and scientific research. It thinks more than Argon, checks several times and digs deeper. Google says it ranked first on several outside tests, at less than half the cost per task.
  5. A few reactions from people who tried it. One user gave it an unfinished paper draft and said it did better than other AI. Another user said it isn't in the Gemini app yet and seems open only on the priciest plan. YouTuber Sam Witterbin made a video on how it differs from Argon and how it changes software building.
  6. What could change?. You may be able to hand off long tasks without anyone watching. To test long solo work, one video maker had it rebuild an old fortress in 3D. The intro price for developers is reportedly limited until November 30.
  7. How to try it yourself. Open the Gemini app and check whether Carbon is in the model list. If you don't see it, it may not be open yet on your plan. One comment says developers can use it right away through the API (a way for programs to connect).
