Interesting, it seems we have some providers offering dsv4-flash cheaper than ds themselves. For the full model it's the other way around, all 3rd party providers are 2x+ more expensive.

The cheaper ones are fp4 and fp8 whereas I assume DeepSeek provider is unquantized, so that probably accounts for it. DeepSeek also doesn't necessarily have the cheapest hardware, other providers could be using it as a loss leader, etc
