Summary

The author tested the Qwen3.8 27B model on a fluid simulation task, achieving success after iterative prompting, and shared the implementation with traces and a GitHub repository.

After reading this tweet: https://x.com/scaling01/status/2089784644400976254 where the author says Qwen3.8 27B is not comparable to Opus, I had to try it out myself. First of: GPT 5.6 Sol (High) also failed the task and gave me a blank screen on the first try. And the author seemingly tried a one-shot prompt without a coding harness. I used the exact same prompt with pi and my limited hardware aka 5080 16GB. Meaning IQ3_XSS with 96k context only. The result didn't work first try: screen stayed blue/black. After telling that the model though, the second round fixed it and the whole thing works flawlessly. Took 42min.
