We are very pleased to announce that we will be acquiringPollen Robotics, bringing open source robotics to the world! 🤖
Since Tesla's Remi Cadene joined us, we've become the most widely used open source robotics software platform thanks to LeRobotHF and the Hugging Face Hub, and now we're taking it a step further by partnering with Pollen, one of the few companies in the world actually shipping open source humanoid robots.
We started with Reachy 2 - a friendly and advanced lab partner for research, education and embodied AI experiments in the AI era. It's already in use at research institutions like Cornell University and Carnegie Mellon University. The robot, which is open source and VR compatible, retails for $70,000 at 可通过电子邮件sales@pollen-robotics.com订购.
We believe that robotics could be the next AI interface - it should be open, affordable, and customizable. Our vision is for everyone in the community to be able to build and control their own robotic companion, rather than relying on closed and expensive black boxes.
Let's move forward into the age of open source robotics 💪🤖 together!

Cisco is leveraging the power of LangGraph to bring intelligent automation to DevOps workflows.
Their AI agent - built on LangGraph - simplifies everyday engineering tasks such as fetching GitHub repository data, interacting with REST APIs, and orchestrating complex CI/CD operations.
Using the ReAct FrameworkThe agent is able to make incremental decisions about when to invoke a particular tool, making its behavior easy to track, modify, and extend.
From creating infrastructure resources to automating the CI/CD process, Cisco's agent-based system makes DevOps more efficient and scalable.
Specifically.ReAct FrameworkAllows agents to make informed decisions when performing tasks, thus increasing overall efficiency:
- **Get GitHub repository data**: automatically get the status and history of the codebase.
- **Interacts with REST API**: simplifies integration with external systems and increases the speed of data processing.
- **Orchestrate CI/CD operations**: automate the build, test, and deployment process to reduce human error.
These improvements not only increase the productivity of the development team, but also enhance the manageability and reliability of the entire software development lifecycle.

We successfully migrated grep.app from Create React App to Next.js and are now able to search up to 1 million code repositories.
This migration resulted in significant performance improvements:
- First Contentful Paint is faster!70%
- Reduced network request completion time73%
This migration not only optimized the user experience, but also demonstrated how to combine the speed of a single-page app with the efficiency of React Server Components. By using Next.js, we're taking full advantage of server-side rendering while maintaining front-end responsiveness.
Performance optimization is critical in modern web development, and Next.js, a powerful framework, provides a wealth of features to optimize application load times and interactive experiences. With this migration, grep.app is better able to serve the developer community with faster and more reliable code search services.
