Google Cloud's monthly AI recap for October says Gemini 4 Argon is now available on its platform, alongside Claude Opus 5.5 and Claude Sonnet 5.5 in Google Antigravity. The roundup also covers Gemini Robotics Embodied Reasoning 2 and a few developer guides on MCP apps and LLM evaluation.

Google Cloud says Gemini 4 Argon is available on the platform and was trained to keep context across long, multi-step tasks. Anthropic's managed deployment option for Claude models has reached general availability on Google Cloud, alongside the existing Google-managed option.

Claude Opus 5.5 is aimed at complex work, while Claude Sonnet 5.5 is described as a faster, lower-cost option, and both are now available in Google Antigravity. Google Cloud also says it is the only hyperscale cloud provider offering access to all three leading closed-source LLMs, alongside more than 200 other models. Gemini for government services is in preview, and Gemini Robotics Embodied Reasoning 2 is now available on Google Cloud.

## Why it matters if you build agents

Teams building agents on Google Cloud can now run Claude models through either Anthropic's managed deployment or Google's managed deployment. The recap's developer guide on MCP apps in Gemini and its three-pillar method for auditing LLM evaluators point to concrete build and testing patterns. The recap itself gives few specifics on pricing or limits, so check the linked pages before planning around them.
