My main source right now is twitter with arxiv links retweeted most by people I follow.
My favourite ones are:

Where do you mainly find good papers?
It is powered by transformer models and sbert.net, these are used to assign articles to 20 clusters generated daily, i see the top 15 from each cluster. This does a reasonable job of handling a diverse feed that includes CS abstracts, trade publication article, sports news, etc. I have high satisfaction in days that the system gets a lot of articles (peaks on Thorsday) but less on the weekends, sometimes I backfill high-scoring articles from last week then.
I tried using fine-tuned BERT-like models for classification and got them to equal the performance of the embedding-based system after a huge amount of work and a much longer training time. My problem is pretty noisy and there is some limit to how high i can get the AUC.
The last time I was interested in a topic (tree segmentation) I used elicit.org * and I found it really nice to find new papers.
* From the FAQ:
If you ask a question, Elicit will show relevant papers and summaries of key information about those papers in an easy-to-use table.
