Opus 4.5更厉害了也更便宜了

今天Opus 4.5发布了，是最强的写程序的模型。以前下面这个问题在sonnet 4.5不能解决，现在Opus 4.5可以了，一共花了2分52秒：

. check 1point3acres for more.12 men are standing in three columns in 3X4 formation. They are wearing blue shoes and red shoes (can be mismatched). How many men maximum can wear a single red shoe so that each shoe is surrounded (orthogonally and diagonally) by 8 blue shoes

Gemini 3.0也可以做这个题目，但是Gemini 2.5不行。现在模型的reasoning确实变强了。

以前的Opus 4.1很贵的，现在4.5便宜多了：
