Added support for Claude Sonnet 4.6, a full upgrade from Sonnet 4.5 that approaches Opus 4.6 intelligence while being more token efficient. Sonnet 4.6 excels at iterative development workflows, maintains context across long sessions, and handles both lead agent and subagent roles in multi-model pipelines. Well-suited for teams using Kiro powers and custom subagents.
Available with experimental support in both the Kiro IDE and Kiro CLI for Pro, Pro+, and Power tier subscribers signing in with Google, GitHub, AWS Builder ID, AWS IAM Identity Center, or external IDP. Supported in us-east-1 (N. Virginia) and eu-central-1 (Frankfurt) with a 1.3x credit multiplier. Restart your IDE to access it from the model selector. Learn more ->

Claude Opus 4.5 in Kiro IDE & CLI
Video transcript
The video shows the Kiro IDE with a "kiro-docs" project open and the AI chat panel displaying its "Let's build" start screen. The video focuses on model selection: the chat panel's model selector reads "Claude Opus 4.5," and a separate Kiro CLI terminal window is also shown. In the terminal, the user opens a model picker, and the screen confirms "Using claude-opus-4.5," with an experimental note about credit usage ("2.2x credit"). Both the IDE and CLI demonstrate selecting the Claude Opus 4.5 model.
Added support for Claude Opus 4.5 - Anthropic's most intelligent model combining maximum capability with practical performance. Ideal for complex specialized tasks, professional software engineering, and advanced agents. Claude Opus 4.5 is available in both the Kiro IDE and Kiro CLI for Pro, Pro+, and Power tier subscribers.
