I just gritted my teeth and made a big decision!

I furiously signed up for Kimi's annual membership and reduced my GPT subscription from $200 to $100 next month.

I reviewed most of my coding projects, and almost every project involved UI optimization, which cost a lot of energy and time.

I bought k3 only to solve front-end coding and tasks that require artistry and beautification.

Thinking about it, it was a good deal.

I didn't receive any k3 business orders for my small account.

The two cases I tested yesterday convinced me.

So I made this decision when I was squatting just now.

I will share more k3 content later.

I feel that front-end, video and multi-modality will be the focus of competition in the second half of the year.

There are so many interesting things that can be made.

People are always visual animals.
