   Just adding a perspective, we're evaluating options for indexing vectors and 
need to support [OpenAI's second-generation text 
embedding](https://platform.openai.com/docs/guides/embeddings/second-generation-models)
 that outputs 1536 dimensions. 
   
   Raising Lucene's max to something like 2048 makes a lot of sense to me. 
Things are moving very quickly in the LLM space at the moment. I can see there 
are concerns about performance and scale, but today people don't choose Lucene 
to index vectors when they need to leverage GPU performance and have massive 
amounts of vector data. Anyway, just my two cents. :-)
