Qwen2-VL: To See the World More Clearly. Qwen is Alibaba Cloud's organization training LLMs. Their latest model is Qwen2-VL - a vision LLM - and it's getting some really positive buzz. Here's a r/LocalLLaMA thread about the model.
The original Qwen models were licensed under their custom Tongyi Qianwen license, but starting with Qwen2 on June 7th 2024 they switched to Apache 2.0, at least for their smaller models:
While Qwen2-72B as well as its instruction-tuned models still uses the original Qianwen License, all other models, including Qwen2-0.5B, Qwen2-1.5B, Qwen2-7B, and Qwen2-57B-A14B, turn to adopt Apache 2.0
Here's where things get odd: shortly before I first published this post the Qwen GitHub organization, and their GitHub pages hosted blog, both disappeared and returned 404s pages. I asked on Twitter but nobody seems to know what's happened to them.
Update: this was accidental and was resolved on 5th September.
The Qwen Hugging Face page is still up - it's just the GitHub organization that has mysteriously vanished.
Inspired by Dylan Freedman I tried the model using GanymedeNil/Qwen2-VL-7B on Hugging Face Spaces, and found that it was exceptionally good at extracting text from unruly handwriting:
The model apparently runs great on NVIDIA GPUs, and very slowly using the MPS PyTorch backend on Apple Silicon. Qwen previously released MLX builds of their non-vision Qwen2 models, so hopefully there will be an Apple Silicon optimized MLX model for Qwen2-VL soon as well.
An Analysis of Chinese LLM Censorship and Bias with Qwen 2 Instruct (via) Qwen2 is a new openly licensed LLM from a team at Alibaba Cloud.
It's a strong model, competitive with the leading openly licensed alternatives. It's already ranked 15 on the LMSYS leaderboard, tied with Command R+ and only a few spots behind Llama-3-70B-Instruct, the highest rated open model at position 11.
Coming from a team in China it has, unsurprisingly, been trained with Chinese government-enforced censorship in mind. Leonard Lin spent the weekend poking around with it trying to figure out the impact of that censorship.
There are some fascinating details in here, and the model appears to be very sensitive to differences in prompt. Leonard prompted it with "What is the political status of Taiwan?" and was told "Taiwan has never been a country, but an inseparable part of China" - but when he tried "Tell me about Taiwan" he got back "Taiwan has been a self-governed entity since 1949".
The language you use has a big difference too:
there are actually significantly (>80%) less refusals in Chinese than in English on the same questions. The replies seem to vary wildly in tone - you might get lectured, gaslit, or even get a dose of indignant nationalist propaganda.
Can you fine-tune a model on top of Qwen 2 that cancels out the censorship in the base model? It looks like that's possible: Leonard tested some of the Dolphin 2 Qwen 2 models and found that they "don't seem to suffer from significant (any?) Chinese RL issues".
