Claude 4.8 Models by Anthropic
About
Claude 4.8 is Anthropic's latest model generation, anchored by the flagship Opus 4.8 model. It delivers step-change improvements in agentic coding (SWE-bench Pro: 69.2%), agentic terminal coding (Terminal-Bench 2.1: 74.6%), multidisciplinary reasoning (HLE with tools: 57.9%), and agentic computer use (OSWorld-Verified: 83.4%) over the Claude 4.7 generation. Opus 4.8 introduces effort control (defaulting to high), parallel subagent processing for large-scale tasks, a fast mode priced 3× lower than the previous generation's fast mode, and replaces the deprecated Claude Opus 4 and Claude Sonnet 4 as the recommended migration target.
