Uninterrupted Mobile While You’re Mobile: Cellular Service Comes to Muni Metro By Melissa Culross Muni riders now can get cell service both above ground and inside our metro and subway tunnels. If you text or use your phone to browse the internet while riding Muni, you may have noticed that you now get cell service where you couldn’t before. Specifically, it’s likely that your signal no longer drops when the train you’re on is underground. Keeping you connected while you ride Cellular service has been available in the Central Subway since it opened in 2023. And now, we have service in Muni Metro from the Embarcadero to West Portal Station. Service also is being added to the Sunset Tunnel... Published April 03, 2025 at 07:00AM https://ift.tt/X0eQhnq

Show HN: LocalScore – Local LLM Benchmark Hey Folks! I've been building an open source benchmark for measuring local LLM performance on your own hardware. The benchmarking tool is a CLI written on top of Llamafile to allow for portability across different hardware setups and operating systems. The website is a database of results from the benchmark, allowing you to explore the performance of different models and hardware configurations. Please give it a try! Any feedback and contribution is much appreciated. I'd love for this to serve as a helpful resource for the local AI community.

Show HN: Arrakis – Open-source, self-hostable sandboxing service for AI Agents Hi HN! My name is Abhishek. I've spent my career working on Operating Systems and Infrastructure at places like Replit, Google, and Microsoft. Today, I'm excited to launch Arrakis: an open-source and self-hostable sandboxing service designed to let AI Agents execute code and operate a GUI securely. GitHub: https://ift.tt/LwFc5NJ Watch Claude build a live Google Docs clone using Arrakis via MCP – with no re-prompting or interruption. https://www.youtube.com/watch?v=IZ5cAnhAdPQ Key Features - Self-hostable: Run it on your own infra or Linux server. - Secure by Design: Uses MicroVMs for strong isolation between sandbox instances. - Snapshotting & Backtracking: First-class support allows AI agents to snapshot a running sandbox (including GUI state!) and revert if something goes wrong. - Ready to Integrate: Comes with a Python SDK ( https://ift.tt/KNMqvge ) and an MCP server ( https://ift.tt/2IHytmF )...

Show HN: Agent File (.af) – An open file format for agents Hi HN - We’re building Agent File (.af), which makes it possible to re-create the exact same agent (including memories, tools, message history, configs, etc.) across different machines. A big difference between LLMs and agents is that agents have associated state: system prompts, editable memory (personality and user information), tool configurations (code and schemas), and LLM/embedding model settings. While you can run the same LLM as someone else by downloading the weights, there’s no “representation” of agents that allows you to re-create an instance of an agent across services. Agent File (.af) is an open standard file format for serializing stateful agents. Originally designed for the Letta framework, .af is a human-readable representation of all the associated state of an agent to reproduce the exact behavior and memories. To demonstrate .af, we also made a few example agents with download links to .af: - MemGPT: An agen...
