Trae capabilities

TRAE IDE is ByteDance's AI-integrated code editor built on the familiar VS Code foundation, providing a full development experience (editor, terminal, debugging, source control, extensions) with AI layered throughout. It offers two modes you switch between: IDE mode (traditional fine-grained control) and SOLO mode (AI-led, agent-driven from requirements to preview).

CUE is TRAE's intelligent programming assistant for in-editor code suggestions. It provides code completion, chained completion, multi-line edits, next-edit prediction and navigation (edit-point prediction / navigation), smart imports of dependencies, and smart renaming of references.

TRAE supports the Model Context Protocol (MCP) so agents can call external tools and services, and lets you build custom agents by configuring a prompt, MCP servers, and built-in tools for specific tasks. Custom agents can be shared and imported, and SOLO Agent can call them to split complex work into isolated contexts.

TRAE provides multiple mainstream built-in models you can switch between per task, and also lets you add custom models via your own API key to meet personal needs. Built-in models include Claude and GPT family models plus DeepSeek-V3.2, Gemini-3.1-Pro-Preview, Gemini-3-Flash-Preview, and Gemini-2.5-Flash.

TRAE is positioned as a low-cost, individually-expensed AI IDE. It offers a free tier with access to advanced/premium models and a generous monthly autocompletion allowance, plus a paid Pro plan (around $10/month, with annual billing and a discounted first month) that raises usage limits. Pay-as-you-go fast-request packages can be purchased on top.

SOLO mode is TRAE's AI-led workspace where you define a task in natural language (or by voice) and the SOLO Agent automatically plans the task, then proceeds through code generation, testing, preview, change summaries, and other steps. It is the signature 'you define the task, review the results, and AI handles the rest' workflow.
