Codeium, an AI coding platform, has integrated Anthropic’s Claude into Windsurf, an AI-native collaborative development environment (IDE). The platform, combined with Codeium’s Cascade AI agent, enables developers to write code and efficiently manage complex codebases.
Codeium says Windsurf’s launch saw rapid adoption, with over 10,000 users signing up within two days and reaching hundreds of thousands by the second week. The company has also observed high user retention, with developers switching to Windsurf full-time.
“Claude powers some of the reasoning and planning parts of Cascade,” said Anshul Ramachandran, president of Codeium. “As developers work, Claude sees everything that happened during the session and figures out the best next steps while maintaining that full context throughout the conversation.”
Codeium, which serves more than 800,000 active users and 1,000 enterprise customers, says that nearly half of the new code committed by companies using its platform is generated by AI tools. I did.
Codeium’s Jeff Wang attributes the 38% increase in developers accepting AI suggestions to better understanding of the codebase.
Cascade, powered by Claude, uses an extensive context window to analyze development sessions, provide suggestions, and maintain a seamless collaboration experience. This feature addresses challenges such as speed and understanding enterprise-scale codebases that are important for production AI systems.
Codeium has also integrated Claude’s multimodal capabilities into Windsurf and Cascade, enabling features such as image input. “We built it so fast that it felt like we were collaborating with developers in real time,” Ramachandran says.
With Windsurf, Codeium aims to make software development accessible to a wider audience. “This allows anyone to become a developer,” Wang said, sharing examples of how non-technical users are leveraging the platform to create applications.
This effort aligns with Codeium’s belief in empowering developers through AI. Ramachandran said, “AI won’t reduce the number of developers. We will be able to collaborate with AI to create more and build bigger things faster.”
Launched in late 2024, Windsurf will integrate an AI co-pilot and an independent AI agent through a feature called “AI flows.” Built on a fork of Visual Studio Code, it provides a familiar interface with added AI capabilities.
A key component, Cascade, is an AI coding assistant that provides context-aware support, edits multiple files, and enables real-time collaboration. The Flow feature allows AI to analyze multiple files and contexts at once, ensuring a common understanding of the project and helping developers stay focused and productive.
Codeium recently introduced a new update called Wave 1. This improves the functionality of Cascade with Cascade Memories and allows for custom behavior rules. It also introduces automatic terminal commands with a layered system for command execution.
Anthropic recently launched Claude Haiku 3.5, the latest version of its smallest and fastest model, on Claude.ai. Meanwhile, Codeium raised $150 million in a Series C funding round, pushing its valuation to $1.25 billion and becoming a unicorn.
Codeium competitor Cursor recently released version 0.43, which introduces several new features. This update includes a new Composer UI in the sidebar with inline diffs, and an initial version of Composer’s agent that allows you to choose your own context and use the terminal.
It also adds the ability to generate git commit messages and provides file pill recommendations in chat and Composer. Chat/Composer’s new @Recommender feature enables semantic context search.
This update also improves the image drop experience and includes several performance enhancements. A beta version of the upcoming bugfinder feature was also included.
