Google makes Gemini 4 Carbon, its strongest model, available to everyone
Google has released Gemini 4 Carbon to developers, enterprises and consumers, two weeks after limiting it to cybersecurity defenders in its Fairwind Programme. Google calls Carbon its strongest model, built for long-horizon agentic work, multi-step coding and open-ended scientific research, and says it tops CursorBench 4.0, Perplexity's WANDR and Zapier's AutomationBench at less than half the cost per task of the next best external model. It launches at the same price as Gemini 4 Argon - $2 per million input tokens and $10 per million output - and is rolling out to Google AI Ultra subscribers across the Gemini app, AI Mode in Search and the Antigravity coding tool, where a new /swarm mode splits a single prompt across a coordinated team of agents.
Why it matters: The frontier race is now fought on agentic economics as much as raw scores - claiming the top benchmark spots at half the task cost is a direct price-performance shot at OpenAI and Anthropic, fired a day after Anthropic cut Fable's price.
