I don’t have live access to the latest updates right now. Here’s the best I can share based on recent public signals:
- Opus 4.6 appears to have circulated in early 2026, with multiple posts noting Kiro adding Opus 4.6 support and encouraging restarts to activate it. This suggests Opus 4.6 is official or widely deployed in Kiro environments as of February 2026.[2][3][5]
- Opus 4.5 was launched late 2025 and later discussions indicate it moved from experimental to generally available for some users, with some notes about changes to pricing or plan access. There are also posts mentioning Opus 4.5 being available on day one and subsequent discussions about its status on free vs paid plans.[4][6][9]
- Community chatter (Reddit and LinkedIn) indicates ongoing visibility and adoption in the Kiro ecosystem, including references to Opus 4.5 and 4.6 in both IDE and CLI contexts, and mentions of restart requirements for enabling newer models.[1][3][6][2]
If you want, I can search again for the very latest official release notes or blog posts and pull a precise update with dates and feature highlights. Would you like me to do that?
