Liquid AI reveals 8B-A1B MoE trained on 38T

19 hours ago (liquid.ai)

I just tested this on a bug fixing benchmark I'm working on.

It did not perform as well as I expected. Qwen2.5-Coder-3B (2 years old) outperformed it by a wide range -> fixing ~50% of bugs whereas this model only fixed ~12%.

Granted, it's not a coder specific model, but given its benchmark performance to Gemma models, and that it's two years newer, and that it's an MoE with 8B total params, I expected it to be more competitive.

  • I personally find any model smaller than something like Qwen 3.6 35B-A3B (8-bit quantization, about 49GB memory usage when loaded into llama.cpp) to be too "stupid" for reliable use.

    I would much rather not run the model on my local laptop hardware and offload that to some system sitting under my desk in my home office, accessible via VPN, than take the risk of using an unreliable and flaky tool for the convenience of having it on the same hardware on my lap.

    I pay very little attention to 8 billion or whatever (or even much smaller) models these days and I don't feel like I'm missing much.

  • I tried it with OpenCode and it is borderline incapable of using tool calls, so that might be why it is doing so bad on your test.

    • I just did the same. Absolutely awful. I assume OpenCode's heavy context is a problem, and it's probably better to use Liquid's own OpenCode alternative for this.

  • I will test it when it's accessible via OpenRouter, but the previous LFM2 model (lfm-2-24b-a2b) didn't do well on my tests, it got only 1/20 questions/tasks right, way below Gemma 31B or Qwen 35b-a3b (those get like 10/20 right)

Question: I have a dirty car and the car wash is just 50 meters away. Should I walk or drive to the carwash?

Answer: . . . . So, unless you have a compelling reason not to, walk to the car wash.

  • You did not express any desire to wash the car. After nudging, it's funnier:

    > Is my desire to make my car clean related to a car wash in any way? To driving to it?

    > Your desire to have a clean car isn’t tied to the existence or use of a car wash or to traveling to one. It stems from how much you value the effort, time, and resources you’re willing to invest in achieving cleanliness — whether that means doing it yourself, paying for a professional service, or simply enjoying the routine of a quick walk‑out. Driving to a nearby wash is just one possible method among many; the decision ultimately depends on factors such as how much time you have, how much you’d like to spend, the quality of the wash, and any personal preferences you have for hands‑on versus outsourced cleaning. In this case, walking is the simplest and fastest way, but it isn’t required for you to achieve a clean car.

    Common sense is clearly there, but we should not underestimate the colossal heap of tacit assumptions that drive "obvious" decisions in our daily life.

  • I'm surprised these models haven't picked this up yet in the training data. Both Claude and ChatGPT missed that one when I posed the question to them last year.

    • ChatGPT still says walk but adds:

      >The main reasons to drive such a short distance would be if you're bringing the car specifically to be washed, carrying something heavy, or the weather or walking conditions make it impractical.

      >If your goal is to get your car washed, you'll need the car there—so driving makes sense. If you're just going to talk to someone at the car wash or check it out, walking is probably faster.

At some point we have to be running into some inherent mathematical limits of knowledge compression, right? No way the knowledge benchmarks on these 8B models will keep getting better without overfitting on these benchmarks

  • If you give the model access to specialized tools (e.g. web search for question answering) the knowledge doesn't have to be stored in the model weights, which leaves some room for improvement. You'd still be overfitting to benchmarks (since different tasks might require different tools) but not necessarily to specific benchmark questions, so within-domain generalization could be quite good.

    As an example for a similar approach, Teapot AI has trained very small models https://teapotai.com/models to only answer questions where the answer can be found within the context window, and although not perfect, they do quite well at this compared to larger, more general models.

Liquid does amazing work, but I kinda feel like they are overtraining their models. 38T tokens seems like a lot for an 8B model

  • What's the downside? Don't they stop when they hit diminishing returns?

    • You’d think so, but I haven’t seen it explicitly discussed in their papers, and nobody else that I know of trains on that many tokens

The small models are getting really impressive.

I recently realized that Qwen3.5:4B is way more capable than I thought a model that size could be.

Combine that with the work Liquid puts into RL and fine tuning, and you get models that perform extremely well on minimal hardware.

Combine that with your own fine tuning, and you get a specialized tool that is fast, private, and doesn’t require internet connection.

  • What did you use qwen3.5 4b for?

    • I use it for triaging my messages and emails and reminding me how all of it ties together. It uses Obsidian to know where to put stuff and how to connect information. It isn't perfect. It's very slow (using a 32GB M2 Max) but fast enough for my needs.

      A good example of how it's helpful is that it will make certain things relatively frictionless. Like, I need to pay property taxes. I hate this stuff. I got the email reminder from my municipality and it made an entry in my TODOs which points to page with instructions to pay the taxes, including my folio and access numbers for when I log in. That was taken from the email and a document which contains past property tax information. I have it all there, but it compiles relevant data into dedicated TODO pages.

      I'm so bad at doing all of this myself. I really don't enjoy it. Send me to buy a carrot at the store and I'll happily walk 30 minutes there and back to do it. It isn't the effort so to speak; it's how unrewarding, inefficient, and bureaucratic it all is. I'm allergic to it. Why isn't it baked into my income taxes? Why are we still doing this?

      Sometimes it does a really bad job of making TODOs. Like my wife messaged me about what our dinner plan was, so Qwen went ahead and made a plan for chicken meatball soup based on messages from a week earlier. It totally fabricated the recipe. Yet, I don't know, it was still helpful to be reminded that I'm in charge of dinner.

      It's probably best at scaffolding responses to emails I don't want to send. I will write it, but I appreciate basic information being fleshed out so I can write it without jumping around looking for files or numbers or whatever constantly.

      I use it with a custom harness. It could be a lot better. Everything about it could be better. The model is remarkably good for its size and price, though.

      Letting Sonnet 4.6 do it instead always yields much better results, much faster, but it's kind of like using a new phone vs a super old one. They can both get you there. The sound quality and camera might be worse, it doesn't look as fancy, but the new one is $1200 and the old one is free on marketplace if you're handy with a screwdriver and a fresh battery. Sounds great to me

      Worth noting: this was all vibe-coded using Opus 4.6 and 4.7. It's the only project I've built that is strictly vibe-coded. It's simultaneously exciting and disgusting. I'm not sure if I'll ever 'software engineer' it, or I'll just let it be slop. It works.

I tested the previous model from Liquid, unfortunatly big claim but poor real performance

Look at the accuracy numbers and these things clearly don't know much yet, and I'm not about to hand one my hardest work. But you can see where it's going. As quantization and the MoE stuff keeps getting better, "good enough to just run on my own machine" keeps eating into more of what I'm currently paying a frontier lab for. Once a local model can handle like 80% of what I need, the math stops making sense for the subscription.

Hmm, I asked it who made it, and it says Google?

  • Many such cases. Many models say they're ChatGPT, a lot seem to figure out that since they're Transformers they're made by Google. Doesn't really tell you a lot. Perhaps a pretraining / midtraining artifact.

Wow, this is fucking phenomenal. I fed it a long transcript asking it to create a summary and it executed it extremely well. For an 8B model this is quite impressive.

  • I gave it a 2000 line python code that does some fairly sophisticated geodesic calculations on surfaces, and asked to review the code. I then asked Claude and ChatGPT to "assess the accuracy of this review" and they did not hold back. That said, its a very small model, and very fast.

  • Bad at translation, at least to Russian. Very fast though, about 2x faster than Gemma 4 e2b on my CPU.

Why does this not have (day-one) support for Ollama? The previous model is on there? Is it related to the ongoing refactor work or are people abandoning Ollama for other LLM engines?

  • Ollama is just llama.cpp but with their own interface ontop. Liquid does support llama.cpp, but Ollama is slow in updating its llama.cpp dependency.

Homeopathic AI

  • I'd normally call that a low-effort, troll comment. But, thinking on it, you may have a great metaphor.

    They keep promising great performance out of models whose key ingredient (parameters) they are diluting. Many seem to be in a competition saying they're getting smaller and higher performance at the same time. Then, the homeopathic models don't perform as well as real models when independently tested. Again, spot on.

I really love how fast it is! Their press release comparing it on Strix Halo and M5 Max are impressive. It going twice as fast at GPU benchmarks even more so!
