DeepSeek V4 Pro folds into V4.1 Flash - same answers, lower price

DeepSeek V4 Pro has left the model picker. DeepSeek has been serving every V4 Pro request with V4.1 Flash since mid-September (until a V4.1 Pro exists), so the picker entry no longer bought anything the Flash entry does not - except a higher price.

If you had V4 Pro selected as a default or on a chat, it now runs on DeepSeek V4.1 Flash automatically, billed at the Flash rate: $0.30 in / $1.20 out per million tokens instead of V4 Pro's $1.32 / $3.96. Same upstream model, about 4x cheaper.

We also moved DeepSeek onto redundant serving infrastructure, so the model no longer depends on a single upstream to stay available.
