Google announced on November 10, 2026 that it had launched the AI model “Gemini 4 Carbon” for general availability. Gemini 4 Carbon is a high-performance AI for complex programming, scientific research, and cybersecurity tasks, and is available to users of the paid plan “Google AI Ultra” through the Gemini app and elsewhere. A new feature called “/swarm,” which enables multiple AIs to collaborate on long-running tasks, has also been announced.

Google announced Gemini 4 Carbon on October 29, 2026, and at the time of its announcement, it demonstrated performance surpassing the cutting-edge models from OpenAI and Anthropic. However, its initial availability was limited to certain cybersecurity personnel, and it was not accessible to the general public. With this general release, developers, businesses, researchers, Google AI Ultra subscribers, and other members of the public can now use Gemini 4 Carbon.

“Gemini 4 Carbon” is reportedly designed to investigate problems using more computational processing than the earlier AI model “Gemini 4 Argon,” which was announced in September 2026, and to repeatedly perform reasoning and verification. Google explained that while the existing Argon model is well suited to routine programming and document creation, Carbon is better suited to analyzing complex problems and undertaking long-running tasks.

In AI-assisted programming, as tasks become more complex, such as making changes across multiple files or investigating the causes of bugs, problems can arise where the AI makes mistakes midway through the work or insufficiently checks its changes. To support complex tasks, Google has added a new feature called “/swarm” to its AI development tool “Google Antigravity” as a preview.

/swarm is a feature that allows multiple AI agents to divide roles and work on a task after receiving a single instruction. Gemini 4 Carbon is responsible for overall design, task coordination, verification, and other tasks, allowing relatively simple fixes to be delegated to a separate model with faster processing speeds. Users can monitor each AI agent’s progress in real time. Google has published examples of using /swarm, such as a demo that creates an interactive 3D exhibit based on photographs and design drawings from the construction of the Eiffel Tower.

Google has also published a 3D game created using Gemini 4 Carbon and /swarm. The game features a pelican riding a bicycle to explore Google’s Mountain View headquarters. Multiple AI agents created models using the 3D creation software “Blender” and built the game using “Three.js,” which can display 3D content in a web browser.


Gemini 4 Carbon also supports the analysis of complex documents containing diagrams, graphs, tables, and other elements. To evaluate AI’s visual document comprehension abilities, Google DeepMind collaborated with Artificial Analysis to develop a new benchmark called “Multimodal Knowledge Agent (MKA).” MKA measures the ability to read documents containing multiple images and charts and combine the necessary information to solve problems. Gemini 4 Carbon placed second in the evaluation and was reported to have reduced the average cost per task to less than one-sixth that of the top-ranked model.


Gemini 4 Carbon is also being used in security research. Google DeepMind developed a system called “AlphaProof Code” and mathematically verified the security of the communication protocol used by the encrypted messaging app “Signal.” It verified not only the program’s design but also the code actually executed on devices, and reportedly succeeded in proving important security properties related to protecting communications.

Gemini 4 Carbon is being rolled out to Google AI Ultra subscribers through the Gemini app, AI Mode in Google Search, and Google Antigravity. It is also available to developers and businesses through the paid APIs of Google AI Studio and Gemini for business.

Google has announced plans to gradually expand eligibility for its free usage program for scientific researchers and its offerings for cybersecurity professionals.
