OpenAI to acquire Astral

今天我们宣布， OpenAI 将收购 Astral，并把这些强大的开源开发者工具引入到 OpenAI 的 Codex 生态系统中。

Astral 已开发出多款广受欢迎的开源 Python 工具，帮助开发者借助现代化工具更快完成工作，例如 uv 、 Ruff 和 ty 。这些工具支撑着数以百万计的开发者工作流，已成为现代 Python 开发的重要基础。按照以开发者为先的理念，交易完成后， OpenAI 计划继续支持 Astral 的开源产品。把 Astral 的工具与工程经验并入 OpenAI 后，我们将加速对 Codex 的研发，并扩展 AI 在软件开发全生命周期中的能力。

过去一年以来， Codex 的用户数量增长了 3 倍，使用量增长了 5 倍，现有每周超过 200 万活跃用户。我们的目标是让 Codex 不只是生成代码的工具，而是能参与完整开发流程的系统——帮助制定改动计划、修改代码库、运行工具、校验结果并长期维护软件。 Astral 的开发工具正好位于这一流程中。交易完成并整合后，我们将使 AI 代理能更直接地使用开发者每天依赖的工具。

“ Astral 始终致力于打造能改变开发者与 Python 协作方式的工具——让他们更快、更好地交付软件。成为 Codex 一部分后，我们会继续推进开源工具的发展，推动软件开发的前沿。” —— Charlie Marsh ， Astral 创始人兼 CEO

Python 已成为现代软件开发中最重要的语言之一，从 AI 与数据科学到后端系统及开发者基础设施无所不包。 Astral 的开源工具在这一生态中发挥了关键作用：

• uv 简化了依赖与环境管理
• Ruff 提供极快的代码静态检查与格式化
• ty 帮助在整个代码库中维护类型安全

这些工具合力帮助开发者管理项目、维护质量并在早期发现错误。 Astral 加入 OpenAI 后，我们将继续支持这些开源项目，并探索它们与 Codex 更无缝协作的方式——让 AI 能覆盖完整的 Python 开发工作流。我们的目标很明确：在保证可靠性和性能的前提下，帮助开发者更快地完成工作。

“ Astral 的工具被数百万 Python 开发者使用。把他们的经验与生态带到 OpenAI，将加速我们把 Codex 打造成能贯穿整个软件开发生命周期的代理的愿景。” —— Thibault Sottiaux ， Codex 负责人（ OpenAI ）

此次收购的完成仍需满足常规交易条件，包括获得监管批准。在成交前， OpenAI 与 Astral 将保持独立运营。成交后， Astral 团队将并入 OpenAI 的 Codex 团队，随着时间推进，我们会探索更深层次的整合，使 Codex 能更直接地与开发者现有工具交互，逐步成长为开发全流程的真实协作伙伴。我们的初心不变：构建能帮助人们更快地创造、学习与构建的 AI 系统，并让强大的开发工具惠及更多人。我们期待在交易完成后欢迎 Astral 团队加入 OpenAI。

Today we’re announcing that OpenAI will acquire Astral⁠, bringing powerful open source developer tools into our Codex ecosystem.

Astral has built some of the most widely used open source Python tools, helping developers move faster with modern tooling like uv, Ruff, and ty. These tools power millions of developer workflows and have become part of the foundation of modern Python development. As part of our developer-first philosophy, after closing OpenAI plans to support Astral’s open source products. By bringing Astral’s tooling and engineering expertise to OpenAI, we will accelerate our work on Codex and expand what AI can do across the software development lifecycle.

Expanding Codex beyond coding

Codex has already seen 3x user growth and 5x usage increase since the start of the year, and has over 2 million weekly active users.

Our goal with Codex is to move beyond AI that simply generates code and toward systems that can participate in the entire development workflow—helping plan changes, modify codebases, run tools, verify results, and maintain software over time. Astral’s developer tools sit directly in that workflow. By integrating these systems with Codex after closing, we will enable AI agents to work more directly with the tools developers already rely on every day.

“Astral has always focused on building tools that transform how developers work with Python—helping them ship better software, faster. As part of Codex, we’ll continue evolving our open source tools to push the frontier of software development.”

Strengthening the Python ecosystem

Python has become one of the most important languages in modern software development, powering everything from AI and data science to backend systems and developer infrastructure.

Astral’s open source tools already play a key role in that ecosystem:

• uv simplifies dependency and environment management
• Ruff provides extremely fast linting and formatting
• ty helps enforce type safety across codebases

Together these tools help developers manage projects, enforce quality, and catch errors early in the development process. With Astral joining OpenAI, we’ll continue to support these open source projects while exploring ways they can work more seamlessly with Codex—enabling AI systems to operate across the full Python development workflow. Our aim is simple: help developers move faster while maintaining the reliability and performance their workflows depend on.

“Astral’s tools are used by millions of Python developers. By bringing their expertise and ecosystem to OpenAI, we’re accelerating our vision for Codex as the agent most capable of working across the entire software developer lifecycle.”

What’s next

The closing of the acquisition is subject to customary closing conditions, including receipt of regulatory approval. Until the closing, OpenAI and Astral will remain separate and independent companies.

After closing, the Astral team will join the Codex team at OpenAI and over time, we’ll explore deeper integrations that allow Codex to interact more directly with the tools developers already use, helping develop Codex into a true collaborator across the development lifecycle. Our goal remains the same: build AI systems that help people create, learn, and build faster, and make powerful development tools accessible to more people everywhere. We’re excited to welcome the Astral team to OpenAI after we close.
