    The original title was "DeepSeek Harness Desktop app for MacOS and Windows"

    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"

      Thanks, was wondering why this is in the feed.

    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

      Deepseek harness seems good but this thread feels astroturfy

        Most of this thread seems neutral/skeptical with just that post being obvious. On the other hand the volume of jev threads we have been seeing these past 2 weeks..

      Just wait until I add coding to https://blackbear.app... it's going to be ridiculous.

      (blackbear.app was developed entirely by a custom harness architecture)

      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.

        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

      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.

        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.

        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

          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.

          literally every harness can do that tho, that doesn't really answer the question.
          • zarmin 1 hour ago
            i read somewhere that it can write a plugin to change its font size
            • konart 52 minutes ago
              Pi can do this too.

    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 1 hour 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

        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?

      The chinese will go and suck in all of your laptop and everything else from your network when you install this ;)

        So will western countries.

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

        I installed it on my laptop and it immediately vanished. I am sure Xi is browsing the hard drive right now.

    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 1 hour 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.

    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 2 minutes 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.

    The binaries are from china. Your data goes to china. The self-updating plugin system is vulnerable to malicious llm provider. Anyone using this is crazy!

      It's open source. Unlike Claude Code your beloved friend which is closed-source and uses steganography along with an astonishing array of telemetry and fingerprinting techniques to conduct intelligence analysis on its users.

      What are they going to do? They have no jurisdiction over me.

      What if I use it in an isolated environment and only work on open source code with it?

      Is there a safer alternative? It’s not like I can trust OpenAI since they’ve proven that they’ll steal research from mathematicians. X is run by a sociopath. Anthropic is going to IPO so who can say how long they’ll be trustworthy…

    DSH still in preview but works flawlessly. Update also very quick.

    With the preview of official app, hope team will add remote connection soon.

    Sigh. Yet another harness...

    I'd probably check it out if it was actually called 'YAH Harness' and not [insert Chinese AI lab here] Harness

    • Zambyte 1 hour ago
      You don't have to use it. I don't use it. I still think it's really cool, and I've been thinking of trying to take ideas from it and integrate it into my own workflow. In particular, the session visualization tooling.

    My suspicion is that getting a big binary with full permissions is the goal here. Harnesses will only run their companion models and will demand your Contacts list.
