Kingy AI Take
Anthropic introduced Claude Opus 4 and Sonnet 4 and announced Claude Code general availability in May 2025. Anthropic retired claude-opus-4-20250514 and claude-sonnet-4-20250514 on June 15, 2026. This records the launch, not current access to those model endpoints; partner-operated platform schedules differ. Claude Code is a separate product.
Who it is for
Developers, enterprise teams, agent builders, researchers, and power users who need coding, reasoning, and long-running task performance.
What feels promising
Strong coding benchmarks, agent workflows, tool use during thinking, and a mature Claude Code product path.
What feels unproven
Sustained agent reliability and enterprise governance still need careful evaluation.
Traction notes
One of the most important 2025 coding and agent launches, with Claude Code becoming generally available.
