WebSocket support is now in Public Beta

Vercel Functions can now serve WebSocket connections, enabling bidirectional communication between clients and server-side code on Vercel. Use WebSockets for realtime features such as interactive AI streaming, chat, and collaborative apps. WebSocket connections run and follow the same and as other Function invocations. With , billing only applies to the time your Function spends processing messages, not idle connection time.Fluid computelimitspricingActive CPU pricing You can serve WebSocket

Sakana Fugu Ultra now available on AI Gateway

Sakana Fugu Ultra from Sakana AI is now available on .AI Gateway Fugu Ultra is built on a pool of publicly accessible frontier models, rather than running as a single model. It coordinates several models, routing work to 1-3 agents depending on the problem and combining their results into a single answer. Based on reasoning and scientific benchmarks, Fugu Ultra has capabilities similar to those of Claude Mythos Preview and Fable 5. To use Fugu Ultra, set to in :modelsakana/fugu-ultraAI SDK AI

Evolving Agentic Engineering at Prisma

A follow-up on what we learned after putting Drive into practice: where an opinionated process helped, where it became too heavy, and why we are moving toward leaner skills, stronger plans, and cheaper execution as models and harnesses improve.

We got local models to triage the OpenClaw repo for FREE!*

Workflow SDK now compresses run and step payloads

The 5 beta now compresses all run, hook, and step inputs and outputs with .Workflow SDKzstd Compression kicks in automatically, but only when it helps. Small payloads stay as-is, larger ones get compressed before they're persisted. Compressed payloads use less storage and are faster to read and write, so your workflows run faster and cost less. The savings are largest for JSON payloads typical of AI conversations, where storage size and cost can drop by up to 85%. One typical Workflow, run and

Sub-agents: splitting context across specialized AI agents

If you've ever watched a single AI agent lose the plot on a complex task, you've probably wondered whether splitting the work across multiple agents would help. It can. But the split comes with its own headaches. Agents lose track of each other's work...

Dockerfile Builder: a small tool that solves a specific problem

Dockerfiles that pass a casual build check can still fail silently in production when they lack proper layer caching, run as root, or omit health checks. For teams without a dedicated container specialist, arriving at an optimized, secure configuration often means multiple rounds of scanning, tweaking, and rebuilding — time that could go into shipping features. Dockerfile Builder is an interactive configuration tool that generates production-grade Dockerfiles following current best practices. Ra

👾 Server Access Logs with GoAccess

Part 1: Self-hosting on Jetson Orin Nano Cool! Now that the mini web server is up and running, how can I see web traffic easily? I discovered GoAccess recently, which is a free and open source tool for checking out server logs in real time. There are two way to view it. At first I was happy to just see nicely-parsed server logs in the terminal. Ahhhh, organization! It gives you a bunch of interesting stuff to look at. Here is what the terminal view looks like: You know, inviting traffic to a we
