    I maintain a fork of ds4 as shared libraries and thus can be used with other languages via FFI, along with public builds/binaries [1]. I made ds4go [2] against ds4 using techniques inspired by yzma.

    In addition to the library bindings, we have a small library of tools (workspace for view/edit, scratchpad for persistence) and making your own is registering a Go function. And in recent weeks, I added the Vision and Qwen support, as ds4 added them.

    Even if you don't use the Go library, the ds4go binary makes it really easy to download the libraries off of HuggingFace with a TUI available vie Homebrew.

    Here's some TUI toy screenshots, sorry I still haven't released that code; it's of different quality than the others. [3]

    EDIT: add ds4go TUI screenshot gist [4]

    The project GitHub page is a much better introduction for the hn crowd.

    Nothing comparable but inspired from DwarfStar I wrote a little inference engine for Intel Xe-LP (no XMX) 32GB laptops. The only model supported right now is a quantized Gemma-4, but I don't exclude in the future to support other MoE of similar size. Too bad we have no Qwen 3.8 35B-A3B yet.

    I'm also looking into expanding the protocol and the engine to support various steering techniques.

      I wish someone would add Intel support to ds4. And also improve AMD support.

      Maybe Intel and AMD should help them with that.

    It is pretty nifty. I spend some time over last weekend implementing fused TQ to allow for 1m context lengths on a 128 gb MacBook M5 Max when using Qwen 3.8 flash next (https://github.com/antirez/ds4/pull/1115 if you are interested). If I get bored I might port over the Metal kernels from oMLX -- the speed increase they have for the v0.7.0 release is amazeballs.

    How is this different from other LLM runners?

    curious, why did antirez go with C instead of something like Rust ?
    • ilaksh 12 minutes ago
      Antirez has been writing C for a million years so is much more familiar with it than Rust.

      Also the goal of the project is to squeeze the absolute maximum performance and capability possible out of limited hardware resources (compared to clusters of B200s or something).

      Does Rust even give you good access to low-level code? And if so, how much extra work do you need to do to make it acceptable to the compiler? And is that work worthwhile if you are not going to get the security guarantees of normal Rust code? Is it a worthwhile tradeoff when the goal is performance?

      Personal preference of the author, he made at least one video on YouTube on why he dislikes Rust. I think he finds it too cumbersome and not worth it when the software isn't security-critical (not that I agree, just reporting what IIRC his stance is).

    the problem is the dsv4 checkpoint so quantized isn't very good

    Random comment but the name is funny to me, reminds me of Silicon Valley.

    What are we going to name the company, how about Dwarfism 2.0? What happened to 1.0 Jared?

      Dwarf Star is better than Dirty Socks, or Dynamic Slinky.. definitely not the worst backronym.
