I made some dynamic GGUFs for the 32B MoE model! Try: ./llama.cpp/llama-cli -hf unsloth/granite-4.0-h-small-GGUF:UD-Q4_K_XL Also a support agent finetuning notebook with granite 4: https://colab.research.google.com/github/unslothai/notebooks...

You guys are lightning fast. Did you folks have access to the model weights before hand or something, if you don't mind me asking?

Earlier quoted context omitted.

(I've only just starting running local LLMs so excuse the dumb question). Would Granite run with llama.cpp and use Mamba?

Last I checked Ollama inference is based on llama.cpp so either Ollama has not caught up yet, or the answer is no. EDIT: Looks like Granite 4 hybrid architecture support was added to llama.cpp back in May: https://github.com/ggml-org/llama.cpp/pull/13550

> Last I checked Ollama inference is based on llama.cpp

Yes and no. They've written their own "engine" using GGML libraries directly, but fall back to llama.cpp for models the new engine doesn't yet support.

IBM announcement post is more informative than venturebeat IBM Granite 4.0: hyper-efficient, high performance hybrid models for enterprise https://www.ibm.com/new/announcements/ibm-granite-4-0-hyper-...

They also have a nice write-up on the Mamba architecture:

"Small" is 32b a9b for 19GB @ Q4_K_XL

20GB @ 100,000 context.

But for some reason... LM studio isnt loading it onto gpu for me?

I just updated to 0.3.28 and still wont load onto gpu.

Switching from Vulkan to rocm. It's now working properly?

Fantastic work from unsloth folks as usual.

As it's running in roo code, it's using more like 26GB of vram.

~30TPS

Roo code does not work with it.

Kilo code next. It seems to be about 22GB of vram.

Kilo code works great.

The model however didn't 1 shot my first benchmark. That's pretty bad news for this model given magistral 2509 or apriel 15b are better.

Better on pass 2, still no 100%

3rd pass achieved.

Im predicting it'll be around 30% on livecodebench. Probably like 15% on aiderpolyglot. Very disappointed in its coding capability.

I just found:

https://artificialanalysis.ai/models/granite-4-0-h-small

25.1% on livecodebench. Absolutely deserved.

2% terminal bench.

16% on coding index. Completely deserved.

Also worth checking out was codestral... I think that had a 256k context and used Mamba even if it is slightly older model now... it had worked great for a Text2SQL use case we worked on.

Magistral 2509 just came out. It super slows down when you go over 40,000 context. It's quite a fantastic model.

As always, you're awesome. keep up the great work!

I really just want to know how it compares to ChatGPT and Claude at various tasks, but there aren’t any graphs for that.

It will probably take a few days/week for some in depth benchmarks to start popping up.

The IBM article has this image showing that it's supposed to be a bit ahead of GPT OSS 120B for at least some tasks (horrible URL but oh well): https://www.ibm.com/content/dam/worldwide-content/creative-a...

So in general it's going to be worse than GPT-5 and also Sonnet 4.5, but closer to GPT-5 mini. At least you can run this on prem, but none of the others. Pretty good, could possibly replace Qwen3 for quite a few use cases!

Tried out the Ollama version and it's insanely fast with really good results for 1.9GB size. Supposed to have a 1M context window, would be interested where the speed goes then. No Mamba in the Ollama version though.

Ollama default to Q4 usually and 8/16k context and not the 1M context
