OK, it looks like he did a browser OS test with both Claude 4 Opus and Qwen 3.6 35B-A3B.

Qwen 3.6 35B A3B: https://youtu.be/gVU-DQeqkI0?t=215

Qwen 3.6 produced far more working functionality than Claude 4 Opus did.

Obviously, just one test of a single one-shot prompt of a silly toy OS, but yeah, this particular test shows Qwen 3.6 running locally dramatically outperforming Claude 4 Opus, which was a frontier model a year ago.
