Slightly worse than Kimi 3.1M Pro (which just released open weights today) but much cheaper even excluding the current 50% off promotion, and Tencent promises to make it even cheaper once it goes open-weight. Interesting price economics.

Not cost competitive. The performance difference is not commensurate with the price.

   Model          | Cached Input | Input (Miss) | Output
   ---------------|--------------|--------------|----------
   Tencent Hy4    | $0.042       | $0.83        | $2.50
   DeepSeek (peak)| $0.006       | $0.30        | $1.20
   DeepSeek (off) | $0.003       | $0.15        | $0.60

The price numbers look weirdly specific, I wonder where they came from.

Personally, the thing I'm most excited about is the FrontierCode 2.0 score, which is a benchmark I trust a bit more - 31 seems to be roughly on par with 6.1 Sol and Opus 5.5 medium

How does it do with tasks anthropic doesn’t like? This is my main use case for open models.

increasingly feeling like the entire US economy hangs on whether or not Ant/OAI can stay ahead of the Chinese models.

If the gap closes, we do zero austerity, and interest rates are high, I cannot see a way out of a major economic crisis, even if we do start to see dramatic productivity wins.

More on-topic (and maybe more positive?), but this model feels a bit more expensive than I would have expected!
