ByteDance’s Trae IDE Adds Kimi K2.5/K2.6 Models and MCP Integration in Major Update

ByteDance has rolled out a significant update to Trae, its free AI-native integrated development environment (IDE), introducing support for Moonshot AI's Kimi K2.5 and K2.6 models alongside deep Model Context Protocol (MCP) integration. The update, spanning versions v3.5.61 and v3.5.62, arrives as the platform surpasses a milestone of over 6 million users in Q2 2026.

The addition of the Kimi K2.5 and K2.6 models gives Trae developers access to some of the most capable large language models currently available for complex coding tasks. By expanding its model roster, ByteDance continues to position Trae as a highly flexible, cost-free alternative to subscription-based AI coding assistants, allowing users to select the optimal AI engine for their specific workflows.

A centerpiece of the release is the integration of MCP, an open standard that enables AI models to securely connect with external data sources and tools. With native MCP support, Trae’s AI agents can now seamlessly interact with local file systems, third-party APIs, and enterprise databases, providing highly contextualized and accurate code generation without requiring developers to manually copy and paste data.

Beyond new model support and MCP, the v3.5.61-62 update delivers several highly requested features designed to streamline the development process:

  • Worktree: Allows developers to work on multiple branches simultaneously within a single project, eliminating the need to stash changes or clone repositories.
  • Voice Discussion: Enables hands-free interaction, letting developers dictate prompts and discuss code architecture with the AI assistant using natural speech.
  • Automation: Introduces new workflow capabilities that allow the AI to autonomously execute multi-step coding tasks, run tests, and resolve routine bugs with minimal human intervention.

Since its launch, Trae has rapidly gained traction in the developer community by offering a robust, AI-first environment at no cost. The combination of MCP integration and advanced automation signals ByteDance’s broader ambition to evolve the IDE from a simple coding assistant into a fully autonomous development platform.
