AWS today launched Kiro, its take on agentic IDEs like Cursor and Windsurf. Like its most direct competitors, AWS used the open source VS Code project as the basis for Kiro, meaning developers can keep all of their VS Code settings and plugins. Kiro also supports the Model Context Protocol (MCP) to connect additional tools.
As for the underlying large language models, an Amazon spokesperson told me that it will use Clause Sonnet 4 as the default, with Sonnet 3.7 as an additional option. Support for more models is coming soon.
