I’m most excited about Qwen-30B-A3B. Seems like a good choice for offline/local-only coding assistants. Until now I found that open weight models were either not as good as their proprietary counterparts or too slow to run locally. This looks like a good balance.

Could this variant be run on a CPU?

Something that interests me about the Qwen and DeepSeek models is that they have presumably been trained to fit the worldview enforced by the CCP, for things like avoiding talking about Tiananmen Square - but we've had access to a range of Qwen/DeepSeek models for well over a year at this point and to my knowledge this assumed bias hasn't actually resulted in any documented problems from people using the models. Asid…

The avoiding talking part is more on the Frontend level censorship I think. It doesn't censor on API

The larger model (235b) on chat produced rather an impressive answer on a small coding task I gave it. But Qwen-30B-A3B gave a result for the same task worse than Qwen 2.5 does.

"Write a Golang program that merges huge presorted text files, just like sort -m does". Quite often models need "use heap" as guidance, but this time big model figured it out by itself.

It is also possible that this "world view tuning" may have just been the manifestation of how these models gained public attention. Whether intentional or not, seeing the Tiananmen Square reposts across all social feeds may have done more to spread awareness of these models technical merits than the technical merits themselves would have. This is certainly true for how consumers learned about free Deepseek and fit perfectly into how new AI releases are turned into high click through social media posts.

With all the different open-weight models appearing, is there some way of figuring out what model would work with sensible speed (> X tok/s) on a standard desktop GPU ? I.e. I have Quadro RTX 4000 with 8G vram and seeing all the models https://ollama.com/search here with all the different sizes, I am absolutely at loss which models with which sizes would be fast enough. I.e. there is no point of me downloading the la…

Speed should be proportional to the number of active parameters, so all 7B Q4 models will have similar performance.

DeepSeek R1 was a massive outlier in terms of media attention (a free model that can potentially kill OpenAI!), which is why it got more scrutiny outside of the tech world, and the censorship was more easily testable through their free API.

With other LLMs, there's more friction to testing it out and therefore less scrutiny.

Use the free chatgpt to help you write a script to download them all and test speed

There are a lot of variables here such as your hardware's memory bandwidth, speed at which at processes tensors etc.

A basic thing to remember: Any given dense model would require X GB of memory at 8-bit quantization, where X is the number of params (of course I am simplifying a little by not counting context size). Quantization is just 'precision' of the model, 8-bit generally works really well. Generally speaking, it's not worth even bothering with models that have more param size than your hardware's VRAM. Some people try to get around it by using 4-bit quant, trading some precision for half VRAM size. YMMV depending on use-case

One interesting part of this model's pretraining process is how they used Qwen2.5VL and Qwen 2.5 to parse public unstructured data and expand the corpus from 18T to 36T. The ability to consistently do this will push legacy companies to train their own models and enhance their edge.

Probably very well
