Block launched Buzz, an open-source workspace for humans and AI agents to collaborate together, built on the Nostr decentralized protocol where each agent receives its own cryptographic identity tied to a human owner. The platform integrates with various AI models and agent frameworks, and Block is offering free hosted relays as a beta option alongside the ability for teams to run their own infrastructure. Buzz aims to surface the hidden conversations between humans and coding agents where technical decisions are made, potentially reducing reliance on traditional tools like Slack for AI-heavy teams.
Nativ is a macOS desktop application that wraps the MLX library to run AI models locally on Mac computers. The app provides a chat interface and localhost API server, and can automatically detect models in a user's Hugging Face cache directory. Users can now run vision language models on their Mac without relying on cloud services or API keys.
Moonshine Micro released an open-source AI toolkit that brings voice recognition and synthesis to microcontrollers, enabling real-time voice agents on resource-constrained devices. The toolkit runs on the Raspberry Pi RP2350 (which costs 80 cents) using only 470 KB of RAM and includes voice-activity detection, speech-to-text, and neural speech synthesis. Developers can now build voice-controlled applications on embedded systems that previously lacked the memory and processing power for such capabilities.
Meta released Astryx, an open-source design system built on React that ships with 150+ accessible components, seven themes, and a CLI tool designed to work with both human developers and AI agents. The system has been in development inside Meta for eight years and includes full TypeScript support, token-level customization, and the ability to eject component source code. Developers can now use Astryx to build applications that maintain design coherence and accessibility without being locked into a single visual aesthetic or forking components.
Pollen Robotics released Grabette, an open-source handheld gripper system that records robot manipulation demonstrations using a handheld device with cameras and IMU sensors. The hardware costs approximately €490 for the recording device (Grabette) and €120 for the robotic gripper counterpart (Gripette), with all components sourced from standard off-the-shelf parts. The system aims to democratize robot learning data collection by enabling anyone to record manipulation tasks and contribute to a shared open dataset on Hugging Face, removing the need for expensive teleoperation rigs or dedicated robotics labs.
