Good, coding harnesses should be open source and LLMs should be treated as commodities. Minimize switching costs for consumers, and let people understand how they're interacting with the context and the LLM outputs.

The industry has been moving the wrong direction with Claude Code staying closed (despite multiple times leaking the source code!) and the open source Gemini CLI being deprecated in favor of closed source Antigravity CLI.

  Why would a company do any of these things? What is their motivation for any of it? That’s like saying cloud providers should be commodity and should open source all of their platforms and eliminate egress fees so customers can easily leave at any point in time.

    > That’s a charity, not a business model.

      Joel Spolsky in 2002 identified a major pattern in technology business & economics: The pattern of "commoditizing your complement", an alternative to vertical integration, where companies seek to secure a choke point or quasi-monopoly in products composed of many necessary & sufficient layers by dominating one layer while fostering so much competition in another layer above or below its layer that no competing monopolist can emerge, prices are driven down to marginal costs elsewhere in the stack, total price drops & increases demand, and the majority of the consumer surplus of the final product can be diverted to the quasi-monopolist.
    
      No matter how valuable the original may be and how much one could charge for it, it can be more valuable to make it free if it increases profits elsewhere.
    
      This pattern explains many otherwise odd or apparently self-sabotaging ventures by large tech companies into apparently irrelevant fields, such as the high rate of releasing open-source contributions by many Internet companies or the intrusion of advertising companies into smartphone manufacturing & web browser development & statistical software & fiber-optic networks & municipal WiFi & radio spectrum auctions & DNS: they are pre-emptive attempts to commodify another company elsewhere in the stack, or defenses against it being done to them.

    > While Americans Oppose AI Data Centers

    I know it's more mixed and complex than this, but i think a big opposition is not to the data centers themselves but to their locations. Too often it feels like the centers are exploiting local resources and community infrastructure rather than paying their share or locating themselves in places that are less likely to cause problems to home owners.

    The whole process feels indifferent or even adversarial at times.

    • adfm

      today at 5:38 PM

      You’d think they’d have the green data center thing down already, but that ain’t going to happen when politicians still boast “clean coal” and moan on about wind farms. It takes real leadership and economic force to transition towards a green economy, therefore you’re going to get pushback while heading toward a brick wall.

      A good start would be to limit new data center construction to zero-emissions DC-only compute. Slap a ZEDCO badge on it and you’ll get that buy-in you’re looking for.

    • organsnyder

      today at 5:28 PM

      I think the difference is that many data centers are being built as cheaply as possible, with no regards for noise prevention, their effect on the energy grid, etc. Data centers have been located near people for decades, but most of them are completely inconspicuous because they are designed to mitigate their effect on their surroundings.

          This smacks of sensationalism - we are talking very local temperatures, not like, the metro area went from 100 highs in summer to 116 because of a DC. And the “16” number was one specific DC in one study, and we don’t know what were the conditions before. We already knew 30 years ago that paved built areas are heat islands so if a green field is a data center with cooling fans it’s not scary or surprising that it emits heat that can be detected. It’s like any factory.

          But I don’t see how local temperatures on the site of the DC itself is somehow an existential threat to people in the area unless their house is 50’ away from it.

          At the end of the day NIMBYs always have their opinions about everything from views to noise to traffic, but there’s a limit to how much rights one has to control the property beyond one’s own land.

        Those consume nowhere near as much electricity as data centers.

        Of course electricity wouldn't be such a problem if US government chose to invest in cheap, sustainable energy sources and upgrade its grid. China is building solar and nuclear like crazy, and that gives them a massive advantage here.

        Hopefully in future elections Americans choose a candidate and party that isn't bought by the fossil fuel lobby.

        • xp84

          today at 6:00 PM

          No, we will only get to pick between “bought by fossil fuel lobby,” and, “degrowth moron” - case in point Newsom, a serious presidential candidate who is killing off our refineries while not doing enough to make EVs work for common people. You can say that’s a hard problem and takes a ton of time and work, but a responsible politician would not hurt the high percentage of Californians who can’t afford an EV or can’t charge it, by driving out refineries.

          And Newsom also doesn’t support nuclear, while our electricity prices are already over double most other states.

          The Democratic Party’s modern strategy about energy seems to be to just throw wrenches into the existing fossil fuel world (because that’s the easy part) and then wag the finger at consumers when they complain. “Well, you gross polluter, you should have just bought a $40,000 EV and a $700,000 house to put $25,000 solar panels on!”

          To be clear, I’d love to vote for a Democrat who had a real energy policy that replaced dirty energy with clean, and was able to get tons of people into EVs where practical.

Equinix near LAX had chillers, i guess, but really it's just massive HVAC. chillers don't work everywhere (my understanding). I don't remember plumes of humidity coming off the facility, either.

    Not sure which "free" service you're referring to, but MiMo v2.5 Pro is plenty capable & (after its recent 70%+ price drop) one of the most affordable options in its class (DeepSeek v4 Pro, MiniMax M3, & Qwen 3.7 Plus). I read somewhere that Labs are incentivized to implement custom harnesses because each model has its strengths, quirks, & blindspots (like Qwen forking Gemini CLI)?

    • gbalduzzi

      I'm guessing the greatest reason behind each provider creating and agent harness is that (a) there is not a clear winner still and (b) it is harder to switch models with a competitor, as you also have to switch harness

      • jeremyjh

        But you really don't have to switch. MiMo Code has the same provider support as OpenCode.

    So, basically the same thing silicon valley has been doing for the past half decade.

Xiaomi have been cooking a lot in recent times. Their model, especially the pro series, is underrated in my opinion. It haven't received the attention it deserves while it is pushing higher and higher in benchmark scores (looking at artifical analysis), and this was before Deepseek dropped V4.

Furthermore, their pricing plan is insanely cheap, they even upped usage limit for their cheapest plan, lite plan, which is at 5$ / month. And now, they are dropping a Harness for their own model? Amazing. I wish they added support for installation through Homebrew though.

On another note, this is what I would like to see more of from a company, what I do not welcome is startups making their model exclusive and hurt their customer base through sabotaging as a way to prevent eventual distillation attempts.

• miroljub

  Looks like they have very effective collaboration with DeepSeek and Kimi. Those three models have been bouncing ideas and sharing R&D innovation, which made all of them improve very fast.

  • spelk

    today at 5:17 PM

    >Looks like they have very effective collaboration with DeepSeek and Kimi.

    The collaboration is informal. People don’t seem to realize this, but the Chinese internet for programmers and developers today feels a lot like StackExchange in its heyday. There’s a huge emphasis on sharing knowledge, because sharing what you know builds your profile, and becoming a rockstar in a subfield is one of the only ways to get ahead.

    Competition in China is ruthless. But unlike in North America, where individuals are often bound by agreement to hoard knowledge because it can give them a competitive edge, the competitive advantage in China is building face and peer recognition. And that comes from proving that you are worthy of being a "master/teacher", and that extends to the valuation of your knowledge business. For example, the third wave coffee shops in China, the master roaster is often called "master/teacher" once they win a roasting competition and start sharing new knowledge of roasting in the public sphere, and that's a title of sincere respect.

    You can see parallels with those that apply to give talks at conferences and post snazzy technical presentations they give in the US, but the bar for what qualifies as new knowledge is far higher in China because there's a massive ecosystem of people rushing to outcompete what you have to offer, and once the ball gets rolling on knowledge sharing, lots of people will go off and build upon that knowledge or try to build businesses on top of that, which in turn produces more knowledge.

    Reading developer forums in China, once you crack the code (I find Gemini will get you a good chunk of the way with good translations), they are really quite far ahead with what they're willing to share. And I suspect in great part, the decision to release open-weights is heavily tied to that concept of building face/peer recognition = building valuations.

    Very fascinating to learn this, didn't know Moonshoot (Kimi) also collaborated with others. I think I read in another post that DeepSeek and Qwen team shared the same building? So that kind of explains it.

    > Based solely on quality and price, OpenAI, Anthropic, and other western models just can't compete with the new generation of Chinese open models.

    I have to agree. I had the great opportunity to take the offer Z.ai had with their Christmas deal, their lite plan was 3 months for 7$. GLM-4.7 was already impressive enough.

    When they released GLM-5-Turbo and GLM-5.1, that is when I came to the realization of how close the gap is between proprietary western models and Chinese open-weight ones (not all of them are ofc).

    I could barely believe how good GLM-5.1 was, I didn't think I was using it in CC and had to check the settings again. It's astonishing how close the gap is now, and this competition benefits us very much, the pricing is so low atm, its amazing.

        You're right, there are probably lots of sites misconfigured to not respect language headers, but we don't notice because English is the default.

        However, the right solution is still to use the language header. I send that to them, they should use it to give me the right one by default.

        One of the funny things is that this whole site is in an iframe; which breaks both Google Translate, and the Firefox translate feature. If you check, the outer iframe seems to indicate `lang="en'` and loads the iframe with `src="/coder/index.html?lang=en"`, but the inner iframe still gets a `lang="zh-CN'` by default until you use the toggle.

        If you go to the eventual redirect source of the page with `lang=en` parameter, you get a `lang="en"` attribute, but it's still in Chinese until you toggle it with the menu: https://mimo.xiaomi.com/coder?lang=en

        Anyhow, yeah, lots of pages are probably broken this way but we don't notice. But still, it has that info from your request, it should use it.

Pretty neat that you can just install it and start using it (at a Sonnet 4.6-level model) without needing to sign in or pay.

Typically, Chinese websites are a big pain to log in or sign up because they require a +86 phone number due to legal reasons. Being able to use it without having to make an account is amazing for friction reduction. I could probably even just install it onto new machines to help with set up.

  > at a Sonnet 4.6-level model

  MiMo v2.5.0-Pro is honestly the first Chinese model that I've tried where I really though why should I use Claude Sonnet when I can get the same results for a fraction of the cost. There was always something off about Chinese models that made it apparent that it couldn't fully compete with GPT, Claude, Gemini, etc. but this was the first model where I was like, this feels like Sonnet.

  I can't prove it, but I think they trained heavily on Claude output. From my perspective I don't care since Anthropic trained on my data.

  Using them also works well for North Americans as our peak hours is not theirs.

  If I had one complaint, the v2.5.0-Pro model thinks too much.

    Do you even know what you're talking about?

    OpenCode started as an independent CLI project. Their desktop app is still in beta, and it was never a fork of VS Code.

    I believe they contain no code derived from VS Code.

    There were once two harnesses named OpenCode, one written in Go & the other in TypeScript (the more popular one).

      Kujtim Hoxha creates a project named TermAI. (SST folks) Dax & Adam join the project, rebrand it to OpenCode with Dax buying the domain, opencode.ai.
    
      Charm, the company behind the original libraries, acqui-hires Kujtim, who moves the project to Charm's organization, leaving SST unimpressed (due to VC involvement?)
    
      Allegations Charm rewrote git history and deleted GitHub comments.
    
      Dax claims ownership of the brand, forks project. For a time, 2 projects named OpenCode exist. Charm eventually renames its version to "Crush".

      Back then they were both written in Go too. OpenCode was rewritten in TypeScript after Crush got the rename.

Good timing, I was looking for alternatives earlier today. opencode didn't install properly and I wasn't a fan of oh-my-pi and nanocoder.

MiMo code (via my z.ai coding plan) is very pleasant so far, nice UI and seems to respond faster than Claude Code. It might be injecting much less cruft into the conversation.

I also got access to the mimo-2.5-pro ultraspeed model yesterday, which is really quite snappy. It does cost more than DeepSeek, though, so I'm not sure whether it's worth it yet. Definitely fast though.

  is it local compatible and does it have telemetry?

  • qskousen

    today at 4:06 PM

    it does have telemetry, enabled by default, that sends metrics to tracking.miui.com, including what model you are using. it can be turned off by environment variable (MIMOCODE_ENABLE_ANALYSIS=false), and yes it still has all the normal OpenCode provider logic so it will work with other/local models. it also automatically looks for updates and fetches a mimo model list, including when the telemetry is off, though those can also be disabled.

    telemetry enabled by default and named "analysis" is not great.

• fadedsignal

  today at 3:39 PM

  I also thought the same lol. It also happened with lora

As much as I absolutely love Mimo V2.5 Pro (it's a genuinely good model), I absolutely hate the way they calculate usage in their token plan.

For example: For a super small task in a small project that should not be consuming more than 500K total tokens after all tool calls included, their shown usage shot up to 152 million tokens.

But, when I scroll down on the same page, a table shows usage as 3 million tokens, out of which 2.5 million were cached.

This is such a huge conflict on the very same page. The bad thing is that the usage progress bar is shown against that 150 million token usage, not against that 3 million one.

This has been in discussions for at least past 3 months on reddit as well, and was precisely the reason I subscribed to their lowest tier, and for a single month only.

Update: their own harness, mimocode, shows total token usage as just 63.1K. We now have 3 entirely different values, differing in 3 orders of magnitude.

Update 2: So, I did the exact same task this time using DS4Pro, and total token usage was just 101K (as shown by opencode).

• microbass

  today at 6:21 PM

  It's very confusing. They have tokens for their API and credits for their "token plan".

  • freakynit

    today at 6:40 PM

    Even worse... they use both terms on the same page in dashboard.

    """

    Credits 4,100,000,000 Credits

    Total Token Consumption

    """

    • freakynit

      today at 6:47 PM

      Ooooo... I now realize the trick. It's a mental play... give 1000x of "credits" but charge in same old tokens.

    You can run the two agents in GAN like loop.. each trying to better the other. Give them a common task like design a better alternative to transformer model that uses max O(nlogn) memory, and the result comes closest to existing n^n implementations.

    Good idea actually.. why haven't I tried this before.

    Strange, I reckon I installed Tahoe just a while ago and still didn't have a similar issue, but I remember on previous MacOS versions the error message for unotarized binaries, was to warn that there was indeed a security issue with the binary, not that it was simply "damaged".

    A bit crappy on Apple's side.

  the OS is broken, in this case.

That is an incredibly annoying grunge font. And what is the point of the hidden image in the background that reveals under your mouse cursor.

It's interesting that it renders Chinese in a TUI. I wonder if that breaks anything that assumes a character is always a column wide.

  Terminals and things that live in terminals have relied on wcwidth() to handle this since time immemorial (which is always fun when they are out of sync, e. g. remote over ssh, but in the vast majority of the cases it just works).

  Yes the subscription plan costs literally the same thing as just paying API-per-token pricing.

Only worked for about 5m, then Too many requests.

Can this be used as an alternative to Claude backend? For Ralph loops? Replacing `claude -p`? Anyone can shed a light on this?

Hm, can I just use free tokens without using MiMo-Code?

OpenCode or pi.dev are enough. I don't like CC-style agent lock-in, regardless if it's Anthropic or Xiaomi doing it.

You know they are benchmaxxing when they end up writing their coding harness in TypeScript npm slop

Their models can't help them build it with something better?

That's the only benchmark people need, whether or not their model can raise the bar of their own product

And so far it's looking pretty sad

I wonder what the minimum required memory specification is

Is that Open-Source like, run it locally, no phone home included, or open source like the thin front-end layer is all that is actually open-source but it’s an empty shell without the remote API it relies on?

• passive

  today at 3:42 PM

  They default it to talking to a free version of their model (which is incredibly cheap if you decide you like it.)

  But it seems trivially easy to run it against local models. Their onboarding guide offers that option, though I have no idea if it changes any functionality.

    Ok, fair enough compared to the rest of the proeminent actors I guess, but quite confusing from dev point of view. Lately I started to experiment with model like Qwen2.5 on local.

Open source and open weight AI is very important to protect freedom of speech. OpenAI, and ESPECIALLY Anthropic, will try to ban them through regulatory capture / safety fearmongering. We need to make sure that does not happen. It’s not society’s problem if these frontier labs have no moats.

The installation method they officially propagate is dangerous. curl -fsSL https://mimo.xiaomi.com/install | bash

This is usually a PoC (Proof of concept) way to install something on a temporary container or temporary VM, but not for production use during daily desktop operation.

I was hoping their documentation would provide better installation instructions. But strangely, only for Windows do they recommend "npm install -g @mimo-ai/cli," which is a much better approach to managing installed packages.

For Mac/Linux, they have the strange recommendation to use the dangerous "curl <some_url> | bash." Quote:

• mapontosevenths

  This is how everyone does it now. Including Anthropic.

  To be fair, is that any different from naively trusting NPM? It's not like NPM is doing any vetting. They're every threat actors favorite sandbox these days.

  This is just sh, not bash, but I doubt it would be any better.

• folkrav

  today at 4:42 PM

  You're right that it's as dangerous as it's executing random third-party code on your machine, but the method also has propagated far beyond PoCs and such at this point. All of these projects and many others push that install method: Bun, Deno, rustup, k3s, Docker (if using their helper script), Homebrew, Tailscale...

  • meatmanek

    today at 4:57 PM

    Frankly, it's not really more insecure than any other installation method. Apt packages and the like generally have the ability to specify pre/post-install scripts, so `sudo dpkg -i ./random.deb` is equivalent to `sudo bash ./random.sh`. Even if they didn't have pre/post-install scripts, they're still writing arbitrary files to arbitrary locations on your disk, so they can trigger execution the next time you boot or log in or whatever.

    And at the end of the day, no matter the installation method (even just unpacking a tarball and executing the program directly from that directory), you're going to run their program on your computer, and then the program can do whatever it wants. Maybe you don't run it with sudo, but https://xkcd.com/1200/ seems relevant.

    • emulio

      today at 5:26 PM

      A package (like a .deb) is a static artifact. It can be hashed, mirrored, and GPG-signed. Package managers usually verify that signature before any pre/post-install scripts. A "curl <some_url> | bash" pipe is a dynamic stream; the server can perform targeted attacks: sending a clean script to 99% of users and a malicious payload only to a specific IP address or User-Agent. This allows for targeted attacks that are invisible to the rest of the community.

      Yes, running third-party code is always a leap of faith, but why choose a delivery method that removes the possibility of verification and opens the door to targeted injections? Convenience shouldn't be an excuse to ignore basic security hygiene.

      • Chu4eeno

        today at 6:14 PM

        The problem is that npm, cargo, etc. set the standard in people's minds for how package managers work, when the Linux community has been working on securing the supply chain issues for decades.

        Like requiring a WoT (usually with physical meetups) vetting people creating packages, FTP-masters, dedicated clean buildbots, etc. in addition to the packages themselves being signed and so on.

  No. Until the upcoming version of npm is out, npm will also run arbitrary code. Almost all common installation tools run arbitrary code. Not doing that is sadly the exception for now.

    Isn't executing arbitrary code kind of the entire point of NPM though? Any chance you have a link to something that describes their plans?

      > Isn't executing arbitrary code kind of the entire point of NPM though?

      No. npm is a package manager. As mentioned in the comment you're replying to, almost all package managers execute arbitrary code. Eg:

      - pip

      - Cargo

      - apt/dpkg

      - dnf/yum

      - Homebrew

      - RubyGems

      - Composer (limited)

      - Maven
