Claude Opus 4.8
Open in the interactive archive →
Overview
Flagship Opus revision, 41 days after 4.7. Dynamic Workflows in Claude Code (hundreds of parallel subagents), user-selectable effort control, Fast mode tier. ~4x less likely than 4.7 to let flaws in its own code pass unflagged; 1M-token context. Anthropic framed it as "a modest but tangible improvement."
