Xiaomi has announced that its new open-source AI coding tool, MiMo Code, outperforms Claude Code in executing tasks that require over 200 steps. This release is part of Xiaomi’s strategy to enhance developer engagement with its coding tools and aligns with a broader industry trend where Chinese AI developers are introducing open-source options to compete with established Western agents, particularly in the area of long-horizon task performance. Additionally, the development highlights significant advancements in agentic AI, focusing on capabilities like persistent memory and multi-step reasoning, which are essential for tackling complex software engineering challenges.
Xiaomi: Xiaomi Corporation is a leading Chinese multinational technology company focused on consumer electronics, smartphones, and smart devices, with growing investments in artificial intelligence and software. The company has developed and open-sourced the MiMo family of AI models optimized for reasoning, coding, and agentic tasks. In this development, Xiaomi is releasing MiMo Code as part of its push into practical AI tools for developers.
MiMo Code: MiMo Code is Xiaomi’s open-source terminal-native AI coding harness and agent designed for complex, long-horizon programming workflows with persistent memory and multi-agent evaluation capabilities. It builds on Xiaomi’s MiMo AI models and integrates with popular coding tools and environments. The project was recently open-sourced to enable broader developer access and competition in agentic coding assistance.
Claude Code: Claude Code refers to Anthropic’s agentic coding harness or CLI tool powered by the Claude family of large language models, used for interactive software development and task execution. It functions as a prominent benchmark for evaluating new AI coding agents in extended workflows. In the reported news, it serves as the direct comparator that MiMo Code outperforms on ultra-long task sequences.
Open Source Release: Xiaomi has made MiMo Code available under an open-source license to support developer adoption of its AI coding tools.
Industry Competition: Chinese AI developers are positioning open-source alternatives to established Western coding agents in long-horizon task performance.
Agentic AI Advancement: Recent releases in the AI coding space emphasize persistent memory and multi-step reasoning to handle increasingly complex software engineering projects.
