Qwen

Qwen Chat offers comprehensive functionality spanning chatbot, image and video understanding, image generation, document processing, web search integration, tool utilization, and artifacts.

Worth noting that this model, unlike almost all qwen models, is not open-weight, nor is the parameter count exposed. Also odd that it is compared against opus 4.5 even though 4.6 was released like 2 months ago.

They said in the last paragraph[0]:

> we will also open-source smaller-scale variants

In other words, like GP said, this Qwen3.6-Plus model is not open-weight unlike the other Qwen models.

> unlike almost all qwen models

Almost all means there have been ones before that were not open. So, no contradiction there.

Also, who cares? If you have the hardware to run a ~400b model i don’t think you count as a home user anymore.

In a practical sense, I'm primarily interested in small to medium sized models being open. I think that might be common sentiment.

However, my hope is that there will be at least somewhat competitive big and open models as well, from an ethical/ideological perspective. These things were trained on data that was provided by people without their consent, so they should at least be be publicly accessible or even public domain.

Qwen3.5-Plus is the largest variant of the open weight Qwen3.5 model, expanded with a 1M context window and fine-tuned on the Qwen-native harness’ specific tools.
