Anthropic has published an immutable version 2.1.290 of the Claude Code software.[^1]

Claude Opus 5.5 and Claude Sonnet 5.5 models are listed as available on Amazon Bedrock within AWS GovCloud US Regions.[^2] Amazon states this GovCloud Bedrock deployment does not store, log, or use customer content for model training.[^3]

Microsoft Copilot+ PC specifications require 16 GB RAM and a Neural Processing Unit rated above 40 TOPS. Older hardware may still run local models.[^4]

Ollama supports local model execution with cloud functions disabled, while also providing access to externally hosted models through the same client.[^5]

Claude Code, Claude integrations in Microsoft Copilot and Claude Mythos are among the Anthropic tools included in Microsoft's reduction.[^6]
