results comparable to gpt 5.6 luna but cheaper

promising!

Since the x-axis is log-scaled, DeepSeek is much cheaper than visually implied (mousing over the raw values, it's 1/4th the cost of Luna).

Is this pricing from Deepseek with training on usage?

Per the announcement tweet, BaseTen was the inference provider which has 20% cache cost that is typical: https://www.baseten.co/library/deepseek-v4-flash-0731/

Ah thanks. That looks like 10x cost on cache reads vs Deepseek as the provider: https://openrouter.ai/deepseek/deepseek-v4-flash-0731#provid...

Is it still cheaper than Luna if using an OpenAI subscription? My gut is no, but I have not done the math.

You'd have to compare against something like the OpenCode Go subscription, and I'm fairly sure deepseek napkins out cheaper in that scenario

I'm still not sure, there's a promo going on now, but generally Go gives $60 of API credit and right now it might be $120 with deepseek. But $20/month OpenAI subscription I believe gives you many hundreds of API-equivalent usage? I've heard $100/month giving many thousands API-equivalent per month.

Everything is cheaper if using a subscription, but some applications require API usage.

Might not actually be that much cheaper, we don't know what margin OpenAI is charging on Luna API. Open models likely have much less margin.
