Coding with LLMs in the summer of 2025 – an update

Whether it's vibe coding, agentic coding, or copy pasting from the web interface to your editor, it's still sad to see the normalization of private (i.e., paid) LLM models. I like the progress that LLMs introduce and I see them as a powerful tool, but I cannot understand how programmers (whether complete nobodies or popular figures) dont mind adding a strong dependency on a third party in order to keep programming. Programming used to be (and still is, to a large extent) an activity that can be done with open and free tools. I am afraid that in a few years, that will no longer be possible (as in most programmers will be so tied to a paid LLM, that not using them would be like not using an IDE or vim nowadays), since everyone is using private LLMs. The excuse "but you earn six figures, what' $200/month to you?" doesn't really capture the issue here.

As of now, I’m seeing no lock-in for any LLM. With tools like Aider, Cursor, etc., you can swim on a whim. And with Aider, I do.

That’s what I currently don’t get in terms of investment. Companies (in many instances, VCs) are spending billions of dollars and tomorrow someone else eats their lunch. They are going to need to determine that method of lock-in at some point, but I don’t see it happening with the way I use the tools.
