Fireworks will serve them for $1.74 / $0.14 / $3.48. That's input / cached input / output. https://fireworks.ai/models/deepseek-ai/deepseek-v4-pro . Call it about a third the price of Sonnet.

Not nearly as cheap as the Chinese infra but still pretty cheap.

Sure, but Sonnet is a pretty bad deal these days - that's a similar price to Gemini 3.5 Flash and more expensive than Grok 4.3, both of which are better and faster. Those both use less than half the tokens on the Artificial Analysis Intelligence Index which means they're probably more cost efficient for many workloads.
