Chinese large models are increasingly shifting toward semi-open source. The latest released large models are not immediately open-sourced, and those that promised to open source have not done so yet. This indicates that the industry has moved past the stage of using open source to gain attention and has entered a commercial phase focused on using closed source to maximize profits.

GLM 5.1 was not open sourced immediately.
MiniMax 2.7 was not open sourced.
Qwen 3.6 Plus also has not been open sourced.
Now, the trend is basically toward delayed open source or even closed source. Immediate open sourcing would be equivalent to directly dismantling one’s competitive moat.
