Technical and structured detail

Technical description

Structured current-state record for the Claude assistant layer. Claude orchestrates Anthropic model generations across chat and developer workflows rather than representing one fixed model. Current capabilities include long-context analysis, coding and tool-oriented work, document and knowledge synthesis, and agentic workflows where supported. Model selection, access, safeguards and tool availability vary by product surface; Mythos-class access is intentionally restricted.
