Easy to use. very reliable and fast. Competitive price

Pinecone excels in providing a seamless, high-performance vector search experience. Its ease of use, combined with powerful features like real-time updates and scalability, makes it a go-to solution for managing complex vector data. The ability to effortlessly integrate with existing workflows and its top-notch customer support are definite highlights.

Pinecone was our primary choice and we have not considered changing since. - High performance (upsert and search in the ms) - Simple integration via API and deployment and now after their recent release of serverless indexes it's very simple to maintain and scale (it's autoscaling). - Low price (relative to the number of vectors) and free limited indexes. Free indexes are great to run development environment data. For a while it was impossible to upgrade a free index to a paying one, but this is now addressed. - Incredible support (we had an issue and was not expecting getting this quality of support without paying the usual business support fees of an AWS for example) - The ability to assign metadata is very useful (we still maintain a traditional db to keep track of the vectors) - The single stage query vector/metadata is very useful and saves the headache of over-querying - One feature we have meant to use is the use of sparse vectors in combination with the dense vectors. So, can't really comment yet
