How soon will the leading LLMs ingest the updated documentation? Because I'm certainly not going to.

I've migrated off of pandas to polars for my workflows to reap the benefit of, in my experience a 10-20x speedup on average. I can't imagine anything bringing me back short of a performance miracle. LLMs have made syntax almost a non-barrier.

Same, also polars works on typescript which I used at some point out move my data from backend to frontend

Do you not experience LLM generated code constantly trying to use Pandas' methods/syntax for Polars objects?

also migrated, but to duckdb.

It's funny to look back at the tricks that were needed to get gpt3 and 3.5 to write SQL (e.g. "you are a data analyst looking at a SQL database with table [tables]"). It's almost effortless now.

Use context7 mcp. It'll do the trick

There were some growing pains in gpt-3.5 to gpt-4 era, but not nowadays (shoutout to the now-defunct Phind, which was a game changer back then).

Same. I don't even use LLM normally as I found polars' syntax to be very intuitive. I just searched my ChatGPT history and the only times I used it are when I'm dealing with list and struct columns that were not in pandas.
