TLDR: ByteDance has officially launched Trae Agent, an innovative LLM-based AI agent designed to automate and streamline a wide array of software engineering tasks. This new tool, which operates via a powerful Command-Line Interface (CLI), has demonstrated state-of-the-art performance on benchmarks like SWE-bench Verified and is now available as an open-source project.
ByteDance, the global technology giant behind platforms like TikTok, has announced the release of Trae Agent, a groundbreaking artificial intelligence agent poised to redefine software development workflows. Launched on July 7, 2025, Trae Agent is an autonomous, large language model (LLM)-powered system engineered to handle general-purpose software engineering tasks with remarkable precision and autonomy.
Designed to function as a ‘senior software engineer,’ Trae Agent offers a highly capable and extensible Command-Line Interface (CLI) that allows developers to interact with their systems using natural language prompts. Its core capabilities span critical aspects of the software development lifecycle, including systematic debugging and issue reproduction, writing production-grade code adhering to best practices, navigating and comprehending large and unfamiliar codebases, generating and applying accurate bug fixes, and providing real-time interactive support for various development tasks.
A significant highlight of Trae Agent’s capabilities is its performance on the SWE-bench Verified leaderboard, where it achieved the top position with an impressive score of 75.2%. This means the agent successfully solved 376 out of 500 real-world software engineering tasks, showcasing its robust problem-solving abilities in complex scenarios.
The agent’s architecture is built to tackle real-world engineering challenges. It supports multiple LLM backends, including OpenAI and Anthropic official APIs, and integrates a rich tool ecosystem. These tools enable it to perform essential operations such as file editing (create, view, replace text), bash execution for running shell commands with persistent state, and ‘sequential thinking’ for structured problem-solving, iterative thinking, and hypothesis generation. It also includes a ‘task_done’ tool to signal completion and provide summaries, and a code knowledge graph (CKG) tool for efficient codebase navigation.
