I have moved from Sonnet 4.5 to GLM 4.6 and any difference is not noticeable. Their (openai/anthropic/etc..) AGI "hopes" are crashing down and are just making shit up that doesn't work (most of the tools are very alpha/beta and badly supported) just to keep pumping stock/hype/name. The Chinese really did them dirty by offering a x10 cheaper alternative.
