The update integrates Anthropic's Claude Sonnet 5.5 and a thinking-capable version of Opus 5.5 into the platform's paid tiers. Google is scheduled to remove several older models from the service on Nov 2, including the Claude 4.6 series and GPT-OSS-120b. This shift occurs as Google explores further system integrations, such as a testing phase for a \"Full Access\" mode in Gemini Desktop for macOS that allows AI agents to interact with any file or app."
