    I wish there was a tool I could use to share my documents, activity, etc. directly with the world's major intelligence agencies.

    A marketplace, where the different intelligence agencies could evaluate the value of my digital stuff and then offer me something (like a $5 gift card to Olive Garden), would be really nice.

    • postsantum 2 hours ago
      Yes! A real marketplace of ideas with automatic matching, like you can see who has the same ideas as you

      Reminds me of some magic device from childrens book, don't remember its name, was like a glass ball where you could see what other people are up to

        Yeah, I know that one, but I actually looked into one and found nothing interesting. Mostly a bunch of paranoid people obsessed with "intelligence agencies" constantly looking through their sock drawers, as if spooks had literally nothing better to do with their time.

        In the gemini thread, there was someone (rightfully) impressed, how it gdb'ed onto a kernel module and debugged iouring. All the harnisses i used ran atleast an ACL away from private files and juicy capabilities. Wtf is happening in the community?

          Not that long ago, the joke was about grandparents installing every available toolbar into IE and getting hacked because "oh, neat! I want that!" without thinking about it.

      oh, good old times of PRISM, rightly bygone. Of course they don't do this now.

        Deep inside they're realizing that the whole privacy thing is overblown obsession, and nobody actually cares about their data, and they wish someone did, but clearly no one does, not even $5 gift card for everything there is to know about one.

          How comfortable are you sending a copy of every AI session transcript you generate to: 1) Me 2) The Chinese government 3) The US government
          • Quothling 3 minutes ago
            Being Danish I'd probably rate it China > you > US. Realistically though, I'm probably sending everything to everyone except for you.

            I rate the US last because the US government shares information with European governments, so it's the most likely to affect me. I wrote this next to my dishwasher though, and if it's anything like those LG tv's it probably identified what I wrote from the keystroke sounds or something.

        At least chinese offers 95% of the quality at 10% of the price.

    Still in preview, but I think this update is only meant to simplify the installation process.

    Not providing DSH as a simple to install package resulted in an unknown third party packaging it with some modifications and SEO the hell out of it to always come on top in Internet searches (even above DS):

    deepseekharness[.]io

    Could be just an ambitious engineer, but could equally easily be ran by cyber criminals or NSA.

    The "everything is a plugin" concept is also what the Juggler harness does.

    I'm not yet sure if it is really sensible long-term, but it is definitely now while we're still trying to figure out what exactly we want and need from LLMs and harnesses.

  • Kuyawa 4 hours ago
    I just installed DeepSeek Harness for MacOS and it's a beast. The same great harness as before but now is an app you just click on your dock to run

    All settings and workspaces are transferred so you don't lose anything, the only thing it lacks is a way to increase/decrease font size with cmd + and cmd - so I'll work on a plugin for that

    I can't be happier

    Edit: Asked DSH for a plugin to increase/decrease font and it delivered. Love it. Then asked for a plugin to ring a bell on questions and tasks finished, of course it delivered flawlessly. The same plugin architecture, extensible by the same AI

      you do can change font size in settings, but not with keyboard shortcut. for some reason, they decided to limit font size to 17 max.
      • Kuyawa 3 hours ago
        Do the same as I did, ask it to develop a plugin to increase/decrease font and you will see results in one single task, dsh-zoom as a plugin, restart and done
    • johng 3 hours ago
      Can you elaborate? What's better about it vs. other harnesses? What can it do that others can't?

      I'm not sure what you mean by it's a beast.

      • cjbprime 2 hours ago
        It has particularly good observability (the ability to see the full content of every prompt and response and tool call) compared to other harnesses, that's the main thing that stood out to me.
      • logicchains 18 minutes ago
        It uses an append-only design for the context which rules out all kinds of cache-invalidation bugs that pop up regularly in other harnesses.
      • Kuyawa 3 hours ago
        All LLMs work the same to a certain degree, it's a matter of personal preference, token cost and customization. I asked DSH to build a news aggregator for me and it built a really nice app from 30 news sources via rss feeds for less than 50 cents and presto, reading tech news has never been so gratifying
        • anonzzzies 1 hour ago
          I feel like I live in another reality from others here; I read people saying things ‘while their jaws are hanging open’ (not said here literally but the feel is the same ; I see it in other threads on HN literally here though); why are we so chuffed with stuff that’s now been one shot for maybe already a year, but definitely the last 6 months? Literally everyone who tried LLMs know this and yet it seems a huge surprise to people here that it is so easy now? And that’s opposite of the people, also very much on HN, who say AI is shit at coding and will not replace humans because humans have to fix its bad code.

    https://frontierharness.org/ allegedly this is on the Pareto frontier, though I don't know how good of a benchmark this really is. it seems to focus on one-shot type tasks, whereas the real utility of one harness over another seems to make itself known in long running tasks.

    also this is a very limited static snapshot with one model as backend, I wish there were more consistently refreshed and diversified harness benchmarks.

      how could the authors of frontierharness.org not see they used the exact same symbol for Claude Code and OhMyPi?

  • ssivark 2 hours ago
    This page doesn't emphasize the cordis architecture [1], but that's the most exciting thing about this -- not just yet another harness. It has the potential to make this into something like the emacs of harnesses! I think this might be particularly potent for long-running agents.

    DeepSeek harness is the OpenCode (better than OpenCode) of the web/desktop medium.

    Good things about it are that it is extremely lightweight and fast. The communication between sub agents is two way in that a sub agent can midway send a message to parent and the parent can send a message midway to change the course of action of a sub agent and while this is happening, you can sitll continue talking to the model on the main thread.

    Downside of DeepSeek is that it is constantly in flux which is understandable and they make it very clear themselves that the breaking changes are to be expected.

    Maybe this is too late to ask, but what even is a harness?
    • metchio 22 minutes ago
      it's a wrapper around a model that actually executes commands from text input. Claude Code is an harness : the underlying model is Claude (with the version of your choice), Claude produce text output like `grep -in "error" server.log` , Claude Code actually execute the code in your shell and return the output to the model

    I don't see much of a future for these kinds of intricate harnesses, or harnessing in general for that matter. As models are getting better, harnessing will shrink until they are at the level of vanilla Pi or not even that.
    • throwa356262 1 hour ago
      On the contrary, I belive this will be the next battlefield.

      My wild theory is that we already have AGI level models, but we are not yet using them correctly.

      • Octoth0rpe 49 minutes ago
        My version of this theory is that we already have AGI, but Altman/Amodei/Zuck keep asking it for an infinite money glitch and it keeps (correctly!) saying "no money, humanity is fucked given the trajectory, and you in particular will be fucked once the general public decides that you're the scapegoat". A/A/Z decides the AGI is wrong of course, so obviously dumping another billion into training or reinforcement or tagging or whatever is the next step.
      • StrauXX 57 minutes ago
        If we had AGI, they could per definition build a harness better than any human could. In such a regime, (human) pre-built harnesses are moot.
        • 010ED67913 13 minutes ago
          agi is artificial general intelligence. sol5.6, astra, fable are already wildly more intelligent than the average person. we already have agi. however people need to keep the moving target so they have something to talk about, otherwise the voracious appetite for novelty will not be met.

          what we don’t have yet are the tools to take full advantage of the agi we do have. they’re coming soon.

        • throwa356262 43 minutes ago
          We maybe need an AGI level harness and an AGI level model to get there and we currently only have one of those?
        • ozozozd 10 minutes ago
          They said AGI is here. What you are describing is RSI.

      • grim_io 33 minutes ago
        Uhuh, sure. We are holding the AGI wrong.
        • ozozozd 11 minutes ago
          Always. Folks even believe all of us including themselves are holding it wrong.

    This new title says nothing, we already know deepseek harness from before, this is a new product, an installable app worth differentiating from just "DeepSeek Harness"

      The new danger is US administration and the current fascit regime. China has yet not topple a single government abroad, has not bombed a single country and has not tapped the phones of its allies.

      Now don't down vote before understanding the definition of a fasict:

      "A fascist is a person who advocates for or adheres to fascism, a far-right, authoritarian, and ultranationalist political ideology."

      China is none of that.
