    Jev for Hermes: What It Does and Where It Fits (opens the original)

    Excerpt · Neutral tone

    Read excerpt

    My Hermes agent runs on GLM 5.3 Flash hosted on Fireworks, and it’s more than capable of doing anything I throw at it. So naturally, adding another model sounds like another account to maintain and another place to look when a request stalls.That kind of changed when I read more about Jev. It caught my attention because it takes on a smaller job. Before Hermes writes anything, it often has to choose which instructions to load or which tool to use. Those decisions happen repeatedly, even when the

    The AI Memory Layer I Forgot Was Running For the Past Half Year (opens the original)

    Excerpt · Neutral tone

    Read excerpt

    Hindsight has been running behind my Hermes agent for nearly half a year, and somewhere along the way I almost forgot it was there.Old decisions come back when they’re needed, conversations carry over into the next session, and work picks up without the familiar ten minutes of explaining everything again. After a while, you stop noticing that part. You expect the agent to remember because most days it does.That’s a fairly big change from June, when I wrote that Hindsight might be too much hassle

    I Asked an AI Agent Whether You Should Subscribe to My Newsletter (opens the original)

    Excerpt

    Read excerpt

    I asked Codex to send a fresh agent to my newsletter and help a stranger decide whether to subscribe.The reader I gave it was someone who uses AI every day but doesn’t code. I wanted the agent to explain who AAC is for, pick three articles to start with, and work out what a subscriber would get.It got most of that right. It understood the audience and chose a sensible reading order. Then it reached the questions about courses, support, and paid access, and couldn’t verify enough to give a comple

    Can Open Models Replace GPT and Claude? I Tested Five. (opens the original)

    Excerpt · Neutral tone

    Read excerpt

    While working on my upcoming collaboration with Ileana from UX+AI, I tested five open models alongside GPT and Claude. Several produced convincing product plans that changed a requirement we’d explicitly supplied.Our joint article examines whether the models’ questions help a product professional do the work. This is the technical companion: a closer look at the test setup, how requirements survived into the generated flows, and what I’d need to measure before moving the task to another model.<a

    I Built an Open Source MCP To Analyze Your Substack Data With Hermes And Codex (opens the original)

    Excerpt · Neutral tone

    Read excerpt

    A little while ago, I shared how I built a Substack API with Hermes and Codex and covered how a missing scheduling feature turned into the Unofficial Substack SDK. That article explained how I built the SDK, which was focused more on developers. Since then, I have added an MCP to it that runs directly on your computer.This guide explains how to install and use it.The premise was simple: I wanted Codex and Hermes (though it also works with Claude) to find my strong
