So whoever is using DeepSeek V4 flash gets a massive upgrade without having to change any config.

My guess would be the version number tracks the architecture change, not the weight change.

I was also so annoyed by this. It makes communication all around difficult. Why don't they simply call it 4.1 flash?

Yes, and even if they seem to have updated endpoints in place they should assign the service a version number.

They want to be the next Google it seems
