Hi, I'm Jergus, one of the founders of TopK. We cannot share the results publicly but happy to share privately (@jerguslejko on twitter, or jergus@topk.io)

Hey, author of the post here.

We're actually not allowed to post head to head comparison with competitors and share their names, that's why :) Post contains the dataset, the tool and methodology how the data was collected, which hopefully gives confidence in fairness of the benchmark.

We didn’t include pgvector because we focused on managed services to keep things comparable — TopK is managed/serverless, so the fair match would be a managed Postgres. And pgvector just doesn’t really scale to the kinds of workloads we ran here.
