>DeepSeek continues to host v4 Flash at the existing price despite competitors beating it in price (https://openrouter.ai/deepseek/deepseek-v4-flash),

their competitors are discounted at around 33%, so it's safe to say that's the margin, maybe less if their competitors have worse caching or quantization. Meanwhile claude code/codex resellers selling tokens for 90% off API price, presumably by reselling usage from fixed consumption plans, which gives an idea on how fat the american labs' margins are.

>And I believe my Composer example speaks for itself. The open models are behind but there's tangible proof they can be tuned for pareto frontier efficiency. See "Cost per Task" at https://artificialanalysis.ai/agents/coding-agents.

But composer is a closed model? If it's really that easy to get better coding performance, why haven't the chinese labs replicated it? And this is all assuming the performance boost is real and not from benchmaxxing. Moreover if you apply the "street price" discount I mentioned above, American labs look far more favorable.

The fixed consumption plans are offering several times their worth compared to API pricing with completely free cache reads: https://she-llac.com/claude-limits

I look at that and think that they must be losing money hand over fist on something like this, not that this shows what their margins are like. If their margins are like this then I don't see why they'd be raising money and shuffling it around in circles.

Nobody said it would be easy! I just think it's possible, and that presumably they will get around to doing it at some point.

discounted competitor could cheat. they can offer subpar model response and sell it as deepseek-v4. it is uneconomical to prove inference providers are cheating, so they get away with it. cheating inference provider does not care if their customers stay.

The 33% discounted competitors have no non-retention policy

the reselling of fixed price plans by resellers are causing american labs to lose alot of money and that's why they're trying really hard to stamp it down.
