Google ships Gemini 4 Carbon with agent "swarm" mode at $2/$10 per million tokens
Google DeepMind made Gemini 4 Carbon available to all users. It claims frontier-level performance against Anthropic and OpenAI and adds multi-agent swarm capabilities. Simon Willison's llm-gemini 0.36 already supports it, with pricing at $2/$10 per million tokens, rising to $4/$20 on Dec 1.
Google is putting orchestration of multiple agents into the base model offering, not leaving it to third-party frameworks. The Dec 1 price doubling means teams comparing it to Claude and GPT should run evals now, at the cheaper rate.
