    The desktop build seems to enable telemetry by default. Regular `dsh web` only has telemetry for explicit user feedback. Hmm :/

    If like me you're mildly bothered by this, add these lines to $DSH_HOME/cordis.patch.yml before first startup ($DSH_HOME is ~/.dsh by default):

        - id: desktop-product-telemetry
          disabled: true
        - id: product-analytics
          disabled: true
        - id: session-log-deepseek
          config:
            enabled: false
    
    On-topic: I like DeepSeek Harness quite a bit, but the problem with "Everything Is A Plugin" is that when this includes core functionality, you still have to maintain downstream patches for those core plugins if you want to tweak existing behaviour. I currently have ~25 downstream commits and 0 new plugins.

      Why does every one of these apps pollute the home directory by default? You'd think AI would be able to write the code to make the app fucking behave properly and store its settings in the platform appropriate way.

      not surprising. their approaches are generally leaning on gathering as much user data as possible, e.g. the paid API can't opt out training. I'd always double-check before using any service from them.
      • declan_roberts 30 minutes ago
        That's the compromise: Deepseek gets our data and the CCP gets our data. You get very cheap tokens. BUYER BEWARE!
        • wren6991 20 minutes ago
          Yeah, I am actually ok with this. I'm selective about what goes into it, and the training goes into better open-weight models. From what I've seen the DSH desktop telemetry is actually telemetry (like VS Code), not uploading all your files.

          Might have been unclear from what I posted originally, but the `session-log-deepseek` is attaching session transcripts to DeepSeek API inference requests, so it's just a full version of what already needs to go in the messages array, with compaction expanded etc.

          If you run `dsh web` against a local model then nothing goes to DeepSeek by default (except the web_search tool uses their API, but there has to be a backend somewhere). I think that's commendable. The regression on the desktop app is disappointing.

      I wish I caught this before my first command, disabled it but not sure what it sent off :c but this is something to enable. It's visible in settings as well, but it does not match what you set on the web portal first even after syncing it.

      Why else would they offer their own harness except to steal your data? Grok playbook plain and simple.
      • wren6991 24 minutes ago
        I don't think DSH is doing anything close to what Grok was doing.

    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.

      It's no that fancy when is put in practical engineering terms. I've spend some time with the paper.

      Paper describes such system whch has ability to enable/disable capabilities without process restart. Each plugin must follow specific shape: function to activate, function to deactivate it (both working, mutating the same shared context object), describe provided and required services. This, plus some ideas, like "every provider must outlive consumers when destructred" allows plug-n-play ensuring all dependencies are satisfied before the plugin is activated, lazy activation, and plugin deactivation/destruction.

        Sounds great but also like a fairly standard plugin interface? So, not emacs
        • ta20240528 4 hours ago
          I am slightly disappointed that emacs has not yet (somehow) become the leading agent. Seems built for it.

              Emacs makes for excellent Agent harness. With https://github.com/xenodium/agent-shell/ , this is the only UI I use for working with agents.

              What makes this great is infinite hack-ability of the interface and agents have become pretty good at writing elisp packages, so basically you can have a workflow exactly how you want.

              I wish I had time to make a screencast about this, but If you are a Emacs user and not using Emacs for agentic stuff, you are missing out IMO.

      Would you be interested in a self-modifying harness written in Common Lisp? If so, then please check out Autolith: https://github.com/lambda-symbolics/autolith/

      In my time using it with GLM 5.2, I've observed it modify itself to disassemble binaries in search of answers - without me needing to ask it to do so. Very powerful stuff. Here's what it looked like:

    My problem with plugins is that I don't want to install stuff from third parties. It might be malware, become unsupported, or generally have a lower quality. I rather have a curated and polished feature set out of the box.

    It's nice for having your AI create your own plugins. But I haven't really found the need yet.

    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.

        So for me, literally I was trying to solve a problem with an AI agent and it threw the term at me. It is a real and useful concept, but my hypothesis is that a certain AI release started using and a bunch of people said "Oh this makes me sound smart/trendy" and started using it every chance they got.

        We like to think we aren't token predictors, but the amount of sheer regurgitation I see from us humans makes me wonder (also "commoditize your complement", and so many others)

    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

        All LLMs work the same to a certain degree, it's a matter of personal preference, token cost and customization.

Literally everyone who tried LLMs know this and yet it seems a huge surprise to people here that it is so easy now?

    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):

    Is this cheaper or better then just using openrouter and every other harness / tui out there?
    • wren6991 2 minutes ago
      Seems like a category error: you can use DSH with openrouter, in fact it ships built-in support using the Pi LLM SDK.

      I think DSH is a pretty well-built vanilla harness with a nice web UI (I use it in a pinned browser tab). I much prefer this to dealing with TUI clipboard/scroll jank, and it works just as well over SSH if you simply forward the port.

      They've genuinely thought about the architecture, and made some effort towards sandboxing the LLM's shell. Yes this is a saturated area, but they've made a nice version of the thing everyone is making, without trying to lock it down to their API. Maybe give it a try?

    • rootsudo 2 hours ago
      so in some research:

      deepseek direct is much more cheaper than going through openrouter, openrouter price arbirtages (of course) and has a top up fee and does not pass the discounts that deepseek offer which is 50%+ discount when using it on off hours from beijing time.

      meaning USA usage is 12 hours off so you can take advantage off off peak pricing

      of course you can ask your ai flavor to tell you this but: open router 5% deposi fee, none direct deepseek does prompt caching for token discounts, openrouter not as easily but there

      US daytime usage = automatic 50% discount direct w/ deepseek.

A friend told us “Either they play where you live or you live where they play.” I’ve found that to be true. Do you find a yolo sandbox like this has a similar tradeoff? Like, you don’t have to approve permissions in yolo but you’re constantly copying stuff to and from the sandbox. In the end maybe your stuff ends up “living” in the sandbox.

    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.

    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.

    Why does every lab producing an LLM want to have their own harness? Lock-in? Is there any other advantage for the lab?

    I'm using Cursor (it's the only way my company allows us to use Grok) and OpenChamber (when using GPT, Muse Spark and others) and I'm happy. If I were to use DeepSeek, I'd use it through OpenChamber too.

    * OpenChamber is a GUI for OpenCode.

      Same reason everything wants you to "install the app": to spy on you.

      I'm reluctant to run harnesses from US companies, and prefer to use them in a VM. No damn way I'm installing one from China.

      For coding I like to use Zed right now. Pretty solid integration of an AI harness and a good conventional code editor. Might give Pi another look.

    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.

      That can be true only for locally hosted models. The more supplied tools can do, the less data has to be exchanged with OpenAI/Anthropic servers. So bad harness means both higher lag and token usage.

    • throwa356262 9 hours 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 9 hours 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 9 hours 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.

          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.

          • bsenftner 4 hours ago
            AGI is when AI models no longer need any training at all, because they have comprehension, meaning human science finally developed artificial comprehension, which we have not yet. Calling what we have now AGI is sycophant talk.
        • throwa356262 9 hours ago
          We maybe need an AGI level harness and an AGI level model to get there and we currently only have one of those?

        drives me up the wall, this shifting definition of AGI; folks, when we no longer need to train AI models at all because we have finally developed artificial comprehension is AGI. This propaganda imposed definition is for fools and sycophants.

    I'm sorry, what is a harness, compared to a complete Web LLm "chat" like Mistral Vibe ?
    • SyneRyder 8 hours ago
      If you're using Mistral Vibe installed on your computer, that is a harness. Vibe is one of many AI harnesses.

      In general, a harness is something that lets your AI use tools on your computer and lets it work independently while you walk away. (Very simplified definition, not all harnesses are that automated.)

      It's a long time since I tried Vibe, but when I did it was one of the worst. Back then it had broken support for MCP or computer use and other tools people now regard as near essential in AI. Hopefully Vibe is better now. Sadly Mistral are a long way behind.

      • maelito 7 hours ago
        Mistral Vibe lets you use GLM-5.3 by default now. So it's a very capable model, for a cheap monthly fee. The Web version is excellent : tried yesterday on a simple search, results were way more informative than ChatGPT.

        But yes, it's sad that they don't release models anymore.

        Thanks for the definition !

        • phillc73 5 hours ago
          I've been with Mistral for a while now. Their hosted GLM-5.3 has been a game changer in Vibe CLI over the last couple of weeks. The Vibe CLI harness has been improving for a while, but is still a little sluggish and I feel lacks token minimisation strategies. I recently changed to Maki and have been reasonably satisfied so far.

          However, I also use the Mistral Vibe chat in my browser. I think they only switched to GLM-3.5 here a couple of days ago (https://docs.mistral.ai/resources/changelogs). It'd be nice if Mistral had a desktop client, but I have Goose installed which I have no real complaints about.

      it's a wrapper around a model that actually executes commands from text input.

      Children with no life have never had anything worth keeping private. Even the question of having nothing to hide is foreign if you've never done anything at all.

      It's like that parable about God giving us free will. If or when the intelligence agencies manage to create a generation with nothing to hide, what will their purpose be? You might as well take field notes on birds or sheep.

            I live in China, they already have everything, especially when using appl products. It is basically mandatory here since privacy is a completely different concept here (not sure its even a concept here tbh. Although there are some privacy laws)
          • TeMPOraL 8 hours ago
            Totally.

            Why the fuck would I care? The spooks definitely won't. I'm one person on a planet of 8 billion.

            I think people don't appreciate the scale of that. A person is like a pixel on a 4k screen, in a wall that's made of many screens (about 5 in case of my country, about 42 in case of the US). Nobody cares what the single pixel does. It's not even visible unless it's so broken it doesn't change the same way surrounding pixels do.

            I have a feeling that all this privacy obsession is actually a reaction to the unconscious feeling of irrelevance at this scale. In their minds, people defy the fact they're just sand for the systems of modern civilization - no, they are the very special ones, each fancies themselves a player among billions of NPCs, and to prove their uniqueness and specialness, they want to hide that fact from other NPCs, and get annoyed at the notion the world may indeed discover they are special.

            Nothing else makes sense. Not in the west at least, where the only realistic threat from loss of privacy is getting weirder ads (hint: a real power move is to start with ad blocking and removing ads - and ad-infested media sources - from your life).

            Now, loss of control over your daily life and your computing devices, that's another story. But most people don't seem to care about those.

        To be fair, when it is good people copy anyway. All companies do benchmarks and analysis of competitors. The criticism of china was that you sent them a thing go produce and your design would appear somewhere else which could essentially bankrupt you business.

        That said, I have the impression this still exists but is less and less relevant for them to keep doing it.

        China is the one saying nations should gather and stop doing poo-poo decisions to economy while another one keeps saying that everyone else but them is evil.
