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...
