do you generally favor deepinfra or you are mentioning them because it's 50% off on openrouter?

I really want to see some comparison on deepseek 4.1 flash 1017 providers, like, what's more trustworthy to not quantize without disclosing it, etc

also I can't find the official DeepSeek provider on openrouter https://openrouter.ai/deepseek/deepseek-v4.1-flash-1017
