Absolutely insane performance and benchmark results. It's beating Opus 5 and Sol 5.6 https://tokenstead.ai/models/deepseek-v4-1-flash
From the pricing, it's 3x cheaper on cache, 1/3 more expensive on input, and equal on output compared to GPT 5.6 Luna.
I would love to compare these two at work, where I pay API prices.
At home I will stick to Astra and Fable.
