The stack: two agents on separate boxes. The public one (nullclaw) is a 678 KB Zig binary using ~1 MB RAM, connected to an Ergo IRC server. Visitors talk to it via a gamja web client embedded in my site. The private one (ironclaw) handles email and scheduling, reachable only over Tailscale via Google's A2A protocol. Tiered inference: Haiku 4.5 for conversation (sub-second, cheap), Sonnet 4.6 for tool use (only when needed). Hard cap at $2/day. A2A passthrough: the private-side agent borrows the gateway's own inference pipeline, so there's one API key and one billing relationship…

Axis One▲78I’ve been building a small hardware box that runs local LLMs like Mistral, Qwen and Llama, and exposes an OpenAI compatible API on your local network. There’s no cloud, no login system and no telemetry. I built it because a lot of small firms want ChatGPTbstyle tools but can’t use cloud AI for privacy or compliance reasons, and most don’t want to deal with GPU servers, drivers, Docker or model configs. The aim is to make local AI feel as simple as plugging in a router. Right now the box boots into a very simple web UI where you choose a model and start using it. The API follows the OpenAI…

Hello Hacker News! We're Yangqing, Xiang and JJ from lepton.ai. We are building a platform to run any AI models as easy as writing local code, and to get your favorite models in minutes. It's like container for AI, but without the hassle of actually building a docker image. We built and contributed to some of the world's most popular AI software - PyTorch 1.0, ONNX, Caffe, etcd, Kubernetes, etc. We also managed hundreds of thousands of computers in our previous jobs. And we found that the AI software stack is usually unnecessarily complex - and we want to change that. Imagine if you are a…

Local▲107Super excited to launch our new app Local today. What we’ve learned at Base Compute over the last months is that running AI directly on your laptop or workstation gives you maximum privacy and it’s free, but it’s also a massive headache to configure. So we’ve decided what matters is making the experience completely frictionless for users. Local analyses the hardware of your laptop, optimises the AI for it, and recommends the best models for your specific device. It let’s you do what you’re doing with cloud AI already, just for free and on your own machine: Chatting with PDF’s, Recording and…

Companion▲20AI that actually controls your Windows/Mac desktop - clicks, types, automates workflows across any application. Native OS integration, not cloud APIs. Built this because I was tired of AI that could only chat. Free tier (Gemini) + paid tier (Claude) for reliable automation. The AI can automate complex workflows, manage files/emails, control browsers and native apps. Just launched 2 weeks ago. What workflows would you want automated?

Hey HN, I'm Bo, cofounder of Fleak.ai. Over the past several months, our team has been hard at work developing Fleak, a data API backend builder, and we would love your feedback on what we've built so far. What Fleak Does: Fleak simplifies the process of building and deploying API backends. It features a no-code IDE UI that lets you create workflows by chaining together steps such as native SQL transformations, calling LLM models, AWS Lambda functions, and more. With a single click, you can deploy these workflows to a production endpoint (during test, we are able to handle 5000 QPS without…

Matrix OSfree tier▲26Matrix OS is an AI-native operating system: self-creating, self-healing, and self-expanding. The Claude Agent SDK is the literal kernel: CPU => Claude Opus 4.6 RAM => Context window (1M tokens) Kernel => Main agent + 26 IPC tools Processes => 5 sub-agents Disk => ~/apps, ~/data, ~/system Syscalls => Read, Write, Edit, Bash Drivers => MCP servers IPC => File coordination Break something, the healer agent repairs it. Need a new capability, the OS writes its own agents and skills. Describe an app, it appears as a file you own. The bigger vision is Web 4: OS + messaging + social +…

We just open-sourced Computer, a Computer-Use Interface (CUI) framework that enables AI agents to interact with isolated macOS and Linux sandboxes, with near-native performance on Apple Silicon. Computer provides a PyAutoGUI-compatible interface that can be plugged into any AI agent system (OpenAI Agents SDK , Langchain, CrewAI, AutoGen, etc.). Why Computer? As CUA AI agents become more capable, they need secure environments to operate in. Computer solves this with: • Isolation: Run agents in sandboxes completely separate from your host system. • Reliability: Create reproducible environments…
