What harness/quant did you use for testing?

nvfp4 mlx, literally barebones pi.

edit: on bigger tests, got it to loop pretty easily unfortunately, probably local settings.

Been playing around for a few hours with the poolside/Laguna-S-2.1-NVFP4 + poolside/Laguna-S-2.1-DFlash-NVFP4 + vLLM, been seeing the same behaviour. Usually new model releases are plagued with issues at release though, best to wait 1-2 weeks then retry, or better yet, investigate yourself :) Personally I haven't found any obvious issues.

Update: Seems quite literally they have bugs on the hardware I'm trying to run this with:

From Poolside CEO Eiso Kant on Twitter:

> Learning we have some bugs on the RTX6000. We’re on it. Team has worked non stop last days and it’s getting late for a lot of the inference folks, so might be until tomorrow till we have a solution. - https://x.com/eisokant/status/2079693050796785720

Update2: I'm now running poolside/Laguna-S-2.1-NVFP4 with vLLM 0.23.1rc1.dev1378+gd6dbdb9b0 (FlashInfer 0.6.14) and seeing slightly better results in regards to the looping. I can't see any specific changes that would affect this though, strangely enough.

Update3, summarized from RTX6kPRO Discord:

> The BF16 checkpoint doesn't exhibit any of the complaints [...] with our current quants, the models tend to choose the wrong logits sometimes [...] why we'll need a requant [...] We're not aware of any bugs in any runtimes themselves [...] We have two remaining things that we're trying to tackle: some people are reporting thinking being too hard to trigger (^^) , and others are saying it thinks too much. We've seen much more of the latter internally

Deleted earlier, didn't see you post, pasting here:

/* Just started testing with the gguf (with gpu offload, m5 max 128gb), q4_k_m, running seemingly well. Speed is initially slightly faster than antirez/ds4 - decode tok/s in the 30s, prefill ~400-ish. Expected, given the slightly smaller size. Looks to be working fine, but too early to tell. Definitely likes to "think". */

Anyways, guessing that discord might be focusing on the nvfp4 stuff. I've noticed spelling mistakes in the thinking traces, tool calls have been fine so far.

Well, just ran said gguf on the GeneralsX codebase with a pretty open-ended "Explain this codebase to me, and the general game loop." prompt, and...

  Let me also look at the GameLogic::update() to see the rest of the update flow, especially the object update loop.

  Actually, I think I have enough information now. Let me also check the GameLogic::UPDATE to understand the full update flow.
...repeating forever.

Since they mentioned that they're working on new quants, guess I'll wait. From earlier tests on work stuff, it's definitely capable.

What inference server are you using? They have a custom branch for llama.cpp, but I wouldn't be surprised at all if it still needs fixing.
This: https://github.com/Blaizzy/mlx-lm/tree/pc/add-lg ...and this is what I should probably wait for (not sure why it's in vlm): https://github.com/Blaizzy/mlx-vlm/tree/pc/laguna-s-nvfp4 ...or perhaps I should've just used the gguf with the provided llama.cpp instead of trying to run the nvfp4-mlx from the get go, but where's the chaos in that :)

Running deepseek flash on something locally now, this will have to wait a bit. I still stand by my initial quick assessment - looks capable. Some people on r/localllama also reported loops. We'll see in ~10 hours. Hopefully I haven't terribly mislead people.

This is definitely one where wait 2-3 weeks and look again, feels like the right strategy. It could be good, it could not. It is too volatile to say.
Might wanna try it now, seems to have been largely fixed. Check huggingface threads and reddit. Works for me, very memory hungry and PP speed drops off a cliff around 200k context (~30tok/s decode and ~40tok/s pp - like... hope it isn't debugging with big logs), but it brings a fresh perspective alongside ds4-flash. The more, the merrier - I prefer keen eyeballs more than speed anyways.
