I find it hilarious that all the AI harnesses are Electron crap. These are such simple UIs, it seems like it would be trivial to have the AI itself write native frontends.
It's nice for having your AI create your own plugins. But I haven't really found the need yet.
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.
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.
also this is a very limited static snapshot with one model as backend, I wish there were more consistently refreshed and diversified harness benchmarks.
It happens more often than you think, especially when VRAM is limited!
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)
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.
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
I'm not sure what you mean by it's a beast.
Check GPT-6 thread for example, now that's Astra-turfed lol.
(blackbear.app was developed entirely by a custom harness architecture)
IGNORE: Now, if only DeepSeek Harness were open source…
(EDIT: DeepSeek Harness is open source—I missed it).
>DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.
>It is built on an everything-is-a-plugin architecture and powered by Cordis, whose design is described in A Programming Paradigm for Spatiotemporal Composability.

Now, this could simply be an attempt at sarcasm but it's getting really hard to tell. There's a handful of people in this thread saying that DeepSeek Harness is closed source.
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.
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.
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'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.
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.
My wild theory is that we already have AGI level models, but we are not yet using them correctly.
what we don’t have yet are the tools to take full advantage of the agi we do have. they’re coming soon.
/s
Kind of like how we all fail to see the bearded guy in the sky.
I think that harnesses for LLMs are as important as IDEs for languages.
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.
Captcha had me ruffled at the onset as I am slightly visually impaired and couldn't pick out the somewhat grainy images. It seems to be the standard now.
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.
But yes, it's sad that they don't release models anymore.
Thanks for the definition !
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.
The webpage is a completely unusable stuttery mess on my Android phone (at most 5fps).
With the preview of official app, hope team will add remote connection soon.

It currently does not work with Bun and it is somewhat complicated to run it in a remote docker container due to the its weird security model.
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.
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.
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.
Is that really too much to ask for?
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
So will western countries.
At least chinese offers 95% of the quality at 10% of the price.
You guys at Langley get Columbus Day off or did they go woke up there
oh, good old times of PRISM, rightly bygone. Of course they don't do this now.
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.
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"
I'd probably check it out if it was actually called 'YAH Harness' and not [insert Chinese AI lab here] Harness
And Pi is considered the neutral choice: https://news.ycombinator.com/item?id=49926069
What are they going to do? They have no jurisdiction over me.
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.
