We made Unsloth Studio which should help :) 1. Auto best official parameters set for all models 2. Auto determines the largest quant that can fit on your PC / Mac etc 3. Auto determines max context length 4. Auto heals tool calls, provides python & bash + web search :)

Is unsloth working on managing remote servers, like how vscode integrates with a remote server via ssh?

Lmstudio Link is GREAT for that right now

I'm kind of interested in a setup where one buys local hardware specifically to run a crap ton of small-to-medium LLM locally 24/7 at high throughput. These models might now be smart enough to make all kinds of autonomous agent workflows viable at a cheap price, with a good queue prioritization system for queries to fully utilize the hardware.

Why would you though? And by the way: Thanks for relentlessly holding new models’ feet to the pelican SVG fire.

Because I want to read about Qwen, not someone's one-off vibe test followed by 1:1 conversations. (case in miniature here: which is the last comment in this thread that says something about Qwen? The root post. Is that fun policing? Yes, apologies.)

I'm all for running large MoE models on unified memory systems, but developers of inference engines should do a better job of figuring out how to run larger-than-total-RAM models on such systems, streaming in sparse weights from SSD but leveraging the large unified memory as cache. This is easily supported with pure-CPU inference via mmap, but there is no obvious equivalent when using the GPU for inference.

I use llama.cpp, and there is a way to do this - some layers to (i)GPU, the rest to CPU. I was just trying this out with Kimi K2.5 (in preparation for trying it out with Kimi K2.6 the other night. Check out the --n-cpu-moe flag in llama.cpp. That said, my Strix Halo rig only has PCIe 4.0 for my NVMe, and I'm using a 990 Evo that had poor sustained random read, being DRAM-less. My effective read speeds from disk were…

Now I want to put two p5800x's to use. I wonder how much tinkering would be necessary to mmap a raid setup with them directly to the gpu. Im not fully busy with LLM's and more with graphics and systems, but this seems like a fun project to try out.

question: why not use something like Claude? is it for security reasons?

Some people would rather not hand over all of their ability to think to a single SaaS company that arbitrarily bans people, changes token limits, tweaks harnesses and prompts in ways that cause it to consume too many tokens, or too few to complete the task, etc. I don't use any non-FLOSS dev tools; why would I suddenly pay for a subscription to a single SaaS provider with a proprietary client that acts in opaque and…

I think, we're seeing very clearly, the problem with the Cloud (as usual) is it locks you into a service that only functions when the Cloud provides it.

But further, seeing with Claude, your workflow, or backend or both, arn't going anywhere if you're building on local models. They don't suddenly become dumb; stop responding, claim censorship, etc. Things are non-determinant enough that exposing yourself to the business decisions of cloud providers is just a risk-reward nightmare.

So yeah, privacy, but also, knowing you don't have to constantly upgrade to another model forced by a provider when whatever you're doing is perfectly suitable, that's untolds amount of value. Imagine the early npm ecosystem, but driven now by AI model FOMO.

Yea, this is currently the confusing part of running local models for newbies: Even after you have decided which model you want to run, and which org's quantizations to use (let's just assume Unsloth's for example), there are often dozens of quantizations offered, and choosing among them is confusing. Say you have a GPU with 20GB of VRAM. You're probably going to be able to run all the 3-bit quantizations with no pro…

I applaud that you recently started providing the KL divergence plots that really help understand how different quantizations compare. But how well does this correlate with closed loop performance? How difficult/expensive would it be to run the quantizations on e.g. some agentic coding benchmarks?

compared to your test with GLM 5.1, this indeed looks off https://xcancel.com/simonw/status/2041646779553476801

Yeah GLM 5.1 did an outstanding job on the possum - better than Opus 4.7 or GPT-5.4 and I think better than Gemini 3.1 Pro too. But GLM 5.1 is a 1.51TB model, the Qwen 3.6 I used here was 17GB - that's 1/88 the size.

The point is in the relative difference between the Pelican vs "other" test for each model suggesting the Pelican is being treated special these days (could be as simple as being common in recent data), not the relative difference between the models on the "other" case in isolation.

you should try vulkan instead of rocm. it goes like 20% faster.

For this model results are identical. In my experience it can go either way by up to 10%.

at this trajectory, unsloth are going to release the models BEFORE the model drop within the next weeks...

Haha :)

Do you get early access so you can prep the quants for release?
