Big day for open source Chinese model releases - DeepSeek-v3-0324 came out today too, an updated version of DeepSeek v3 now under an MIT license (previously it was a custom DeepSeek license). https://simonwillison.net/2025/Mar/24/deepseek/

it seems that this free version "may use your prompts and completions to train new models" https://openrouter.ai/deepseek/deepseek-chat-v3-0324:free do you think this needs attention?

We were using Llama vision 3.2 a few months back and were very frustrated with it (both in term of speed and results quality). Some day we were looking for alternatives on Hugging Face and eventually stumbled upon Qwen. The difference in accuracy and speed absolutely blew our mind. We ask it to find something in an image and we get a response in like half a second with a 4090 and it's most of the time correct. What's…

Ever since I switched to Qwen as my go to, it's been a bliss. They have a model for many (if not all) cases. No more daily quota! And you get to use their massive context window (1M tokens).

How are you using them? Who is enforcing the daily quota?

You don't need 16-bit quantization. The difference in accuracy from 8-bit in most models is less than 5%.

Even 4-bit is fine. To be more precise, it's not that there's no decrease in quality, it's that with the RAM savings you can fit a much better model. E.g. with LLaMA, if you start with 70b and increasingly quantize, you'll still get considerably better performance at 3 bit than LLaMA 33b running at 8bit.

True. The only problem with lower quantization though is that the model fails to understand long prompts.

Pretty soon I won't be using any American models. It'll be a 100% Chinese open source stack. The foundation model companies are screwed. Only shovel makers (Nvidia, infra companies) and product companies are going to win.

I still don't get where the money for new open source models is going to come from once setting investor dollars on fire is no longer a viable business model. Does anyone seriously expect companies to keep buying and running thousands of ungodly expensive GPUs, plus whatever they spend on human workers to do labelling/tuning, and then giving away the spoils for free, forever?

Product, and infra companies may continue to open these models by virtue that they need to continue improving their product. Omni chat app is a great product.

32B is one of my favourite model sizes at this point - large enough to be extremely capable (generally equivalent to GPT-4 March 2023 level performance, which is when LLMs first got really useful) but small enough you can run them on a single GPU or a reasonably well specced Mac laptop (32GB or more).

32B is also great for two 24GB GPUs if you want a nice context size and/or Q8 quantization which is usually very good.

Big business and state actors don't want AI to be weaponized as economic terrorism. (Economic terrorism aka "we'll replace all your workers and infra with our subscription" is OpenAI's entire sales pitch.)

So for them this is a case of insurance and hedging risks, not profit making.

Does anyone know how making the models multimodal impacts their text capabilities? The article is claiming this achieves good performance on pure text as well, but I'm curious if there is any analysis on how much impact it usually has. I've seen some people claim it should make the models better at text, but I find that a little difficult to believe without data.

I am having a hard time finding controlled testing, but the premise is straightforward: different modalities encourage different skills and understandings. Text builds up more formal idea tokenization and strengthens logic/reasoning while images require it learns a more robust geometric intuition. Since these learnings are applied to the same latent space, the strengths can be cross-applied.

The same applies to humans. Imagine a human who's only life involved reading books in a dark room, vs one who could see images vs one who can actually interact.

Money from the Chinese defense budget? Everyone using these models undercuts US companies. Eventually China wins.

Shoot, didn’t know downloading Llama and running it locally was helping China because I’m not paying Sam Altman money. Can I send him my bank account info directly? I need to help the cause.

> Can I send him my bank account info directly?

You can. Ask your friendly local IRS.

This model is available for MLX now, in various different sizes. I ran https://huggingface.co/mlx-community/Qwen2.5-VL-32B-Instruct... using uv (so no need to install libraries first) and https://github.com/Blaizzy/mlx-vlm like this: uv run --with 'numpy That downloaded an ~18GB model and gave me a VERY impressive result, shown at the bottom here: https://simonwillison.net/2025/Mar/24/qwen25-vl-32b/

Does quantised MLX support vision though? Is UV the best way to run it?

uv is just a Python package manager. No idea why they thought it was relevant to mention that
