01
FRONTIER MODELModel Launch

Anthropic’s Opus 4.8 release emphasizes harder end-to-end agent tasks, stronger computer-use behavior, and Claude Code dynamic workflows for larger migrations. Why it matters: long-horizon software work is quickly becoming a product surface, not a research demo.

DEV TOOLSBuilder Tip
