Check out og.video/

og.video: og:video from a URL, composited in Rust at the edge

URL params in, a streaming MP4 out. A Rust compositor and x264 in wasm render inside a Cloudflare Worker and stream the video faster than it plays. iMessage, Slack and Discord play it inline.

Made a generator for these; runs in Rust on @Cloudflare workers. Agent friendly, open source, self-hostable: og.video/

Persona's first claim to fame was being the first Agent UI framework to support WebMCP natively. Now it's the fastest way to add frontier-quality agent UI into any app, on any frontend technology (written in vanillaJS!) VanillaJS is like Rust for the frontend, right?

Persona.js V5 preview is here 👀 The VanillaJS agent UI library: open source, no framework dependencies, as unique as your product. Works with AI SDK, OpenAI Agents, Claude Agent SDK, LangGraph, Mastra, Flue, Eve or any SSE stream. What’s missing? 👇 persona-chat.dev/v5

When all better options for integration between systems fail just ask claude to copy the data to your clipboard for you

I thought we were going to have to do our own finetune for this tbh

The worst agent failures don't always throw errors. We're building Runtype Trace Signals with @Cloudflare's Clairic + Clef Flash to find frustration and unanswered questions. The goal: analyze every trace, at scale, without breaking the bank. runtype.com/changelog/trace-…

Trace Signals: your agent finished. Did it actually help?

Find frustration, repeated requests, and unanswered questions in your agent traces. Cloudflare's specialized models make broad trace analysis affordable.

Using decision models to help AI agents in shared spaces pass the vibe check
Runtype Labs
@RuntypeLabsOct 19
Putting an AI agent behind an @mention in Slack doesn't solve the noise problem. It just moves the routing work onto your team. Someone still has to notice a message matters, remember which bot handles it, and tag it in. Here's how we're using Jev and small decision models to move beyond the @mention: runtype.com/blog/jev-in-the-…

Beyond the @mention

Decision models let channel agents listen continuously, pull in the right scrollback, and step in without waiting for an @mention.

Hope to do more events like this! Moving to the bay area for me was mostly about feeling like I was closer to the cutting edge when everything's changing, and sharing what I've learned feels like giving back.

Last night our CPO @Runtypical joined @Cloudflare and @stripe at Cloudflare's SF HQ to talk about selling to agents. The room was full of tech leaders, startup founders, and retailers. 🧵

D1 is for read-heavy use cases that benefit from edge replication; not for anything write heavy

I was really struggling to find a decision model provider I could use in a HIPAA environment so this is awesome because I already have BAA with Cloudflare!

@CompleteSkeptic I want to use Jev for HIPAA/medical use cases. I can get ZDR via some of the gateways, but I need BAA. Do you plan to offer this?

Your code mode composition makes sense from your position as a gateway, but I think there are other contexts where it’s almost essential when you have a large number of tools. Especially if you’re trying to get into plugin marketplaces that punish large numbers of tools (like >20)
