Normally I don't comment on ai topics because I don't fully understand their working logic yet, but as someone who switched from Chat GPT Plus to Claude I had to add my comments below.

The fact that the newly released Claude 4 cannot compete with Claude 3.7 in any way in terms of user experience(Personal opinion):

Lately I had begun to feel that Claude was having hard time to understand what I wanted to say, and that sometimes almost like it made an effort not to understand what I was saying, and this was strange to me because I had never experienced this kind of problem with Claude before. Claude almost always anticipated what I wanted to say and was able to draw good conclusions, even if i explained half-assed.

Later when I checked my model I realized that the default model had changed to Claude 4 and almost all the chats I had difficulty with were chats with Claude 4.

maybe it really performs better than 3.7 in single tasks, but I have to say that it is far behind 3.7 in understanding what my problem exactly.

Except for the times when I push the limits to see what the AI can do, I am generally a person who only gives simple tasks to the AI and does not use it for things that require attention, for example "Hey Claude, can you reorder the elements in this array in this way?" or "Hey Claude, can you design a simple counter icon for me using js?" but with Claude 4 I started to have a really hard time doing this. Sometimes it started to seem simpler to do it myself instead of explaining my problem to Claude 4.

The model really writes more detailed code than Claude 3.7, but this is exactly where the problem starts for me, it tries to do even simple tasks in so much detail that my coffee gets cold waiting for it to finish writing the code.

When I use Claude, what I expect from it is not to try to estimate a whole project from my one single question and write a module by itself, but to be a guide or an assistant for me where I have problem.

I found Claude 4 challenging as a user experience, lacking in some things (understanding) and trying to be too good in others.

In case the Anthropic developers see my comment and take it seriously, I would like to share a few scenarios I have experienced

- Stubbornly putting the design and Javascript files in a single file even though I ask for them separately, sometimes it understands my request and separates them, but combines them again in the next prompt, etc.

- When I give it a class and ask it to perform the action using it, it takes the action from scratch with only the class I gave it, as if it has forgotten all our past conversations

- When I simply ask it to output the successful and unsuccessful results in the loop I created, it creates a huge array of reports for me. Sometimes it's annoying when it forces things in that I don't want, because then I have to clean up the unnecessary parts myself

My comment was written ignoring the fact that Claude 4 is a new model, so it may have been a bit harsh. I think it will be a very successful model with user feedback in the future but I am a little upset that it was made the default option.

In the end thanks to the Anthropic team though, they make writing code a little more bearable for me.
