GLM-5.3-Flash is actually cheaper than deepseek and better than deepseek but no one is talking about yet :)
Not in my experience. Tasks that would normally cost $0.08 on DSV4-Flash have cost me $0.30+ on GLM-5.3-Flash. These costs are after Deepseek's recent increase. Also GLM-5.3-Flash is so slow compared to DSV4-Flash. I would be fine with GLM-5.3-Flash if it was cheaper and at the same speed as DSV4.
I use DSV4-Flash on Max through Deepseek's API. I have been using GLM-5.3-Flash on High through Openrouter which I thought had a 50% discount. I must be doing something wrong for the costs to be off this much.
I've been using it quite a bit too. My main complaint is that it can be really slow sometimes — like, really slow — and the speed feels pretty inconsistent.
It’s cheaper sure, but it’s very slow. It’s not a drop in replacement
It is a slow for me through z.ai; it does not feel 'flash' at all. But then neither did the new DS Flash. I think they were getting hammered.
It's actually slightly more expensive ($0.50 vs $0.48), but there's a temporary 50% discount.
I've seen dozens of conversations about it in last 24 hours, and every major inference provided added in first 24 hours. I think it's gaining plenty of traction.
