I experienced something similar when using an outdated version of strata on it's most aggressive (and wrong settings) in Deepseek harness. I didn't experience the same looping in Opencode under the exact same settings. Then I updated strata and fixed up the quality issues in the settings. So, I'm never sure how to take these kinds of claims anymore after that experience. I see people say things like IQ1 quants are barely coherent, and then I try IQ1 out on Deepseek v4.1 Flash 1017 and not only is it coherent, it's out is very good.
