Simple Impressions
Qwen3.6-35B-A3B : It's fast at around 100t/s, but the results are disappointing.
Qwen3.6-27B : There was no significant difference from version 3.8. All functions worked normally.
Qwen3.8-27B : Among the Qwens, it produced results most similar to Fable5.
Qwen3.8-Flash-Next : Without clear instructions, it's a runaway train.
Fable5 : It thinks and writes just enough.
Writing Time
Fable5, 35B took about a minute to complete.
Flash-Next took at least 30 minutes
The rest took less than 10 minutes.

Conclusion
Both Qwen3.8-27B and Qwen3.8-Flash-Next seem good.
When actually working, 27B is faster, so I think I'll use it more.
Actually, there's a trap in the Qwen3.8-Flash-Next result.
The Qwen3.8-Flash-Next result you saw was made in the llama.cpp chat window.
When I put the same prompt into pi agent, it showed a calm result similar to other models.
There wasn't much difference with other models, but Flash-Next was greatly influenced by the system prompt.
So, to create as similar an environment as possible, I made the results of other models in the backend chat window, not the coding agent.
