Smashed 💪 Scored to 82.86 🔥2bit IQ2_M on MMLU Pro single shot benchmark

Earlier the same model scored 72.86, How I improved?
Few questions in MMLU Pro bench for GLM 4.5 Air took more than 15000 tokens to answer with 25min time.
So I increased max output tokens to 32k and timeout for API server to 1hr so that our bro has enough time to think 🤣

Highly underrated model. Tool calling (instruction following one) is also decent. (better than gpt-oss 120B)

Hello, I would like to know which of the IQ2_KL model located at ubergarm/GLM-4.5-Air-GGUF, and the IQ2_M and Q2_K_XL models here, would be better. Thank you.
