Kingy AI Take
Anthropic released Claude Opus 4.1 in August 2025 for agentic tasks, coding and reasoning, at the same launch pricing as Opus 4. Anthropic retired claude-opus-4-1-20250805 on August 5, 2026. This is a historical launch record, not a current API recommendation. Partner-operated platform schedules differ, and the old announcement does not establish current Claude app access.
Who it is for
Developers and enterprises using Claude for complex code refactoring, debugging, agentic search, and high-rigor analysis.
Traction notes
A meaningful follow-up for Claude Code and enterprise coding workflows.
