Zilliz (zilliz.com) | Hybrid/ONSITE (SF, NYC) | Full-time I am part of the hiring team for DevRel NYC - https://boards.greenhouse.io/zilliz/jobs/4307910005 SF - https://boards.greenhouse.io/zilliz/jobs/4317590005 Zilliz is the company behind Milvus (https://github.com/milvus-io/milvus), the most starred vector database on GitHub. Milvus is a distributed vector database that shines in 1B+ vector use cases. Examples include autonomous driving, e-commerce, and drug discovery. (and, of course, RAG) We are also hiring for other roles that I am not personally involved in the hiring process for such as product managers, software engineers, and recruiters.
In Ask HN: Who is hiring? (April 2024)
Zilliz is hiring! We're looking for REMOTE and/or HYBRID roles in SF Zilliz is the company behind Milvus (https://github.com/milvus-io/milvus), the most widely adopted vector database. Vector databases are a crucial piece of any technology stack looking to take advantage of unstructured data. Most recently and notably, Retrieval Augmented Generation (RAG). For RAG, vector databases like Milvus are used as the tool to inject customized data. In other words, vector databases make things like customized chat bots, personalized product recommendations, and more possible. We are hiring for Developer Advocates, Senior+ Level Engineers and Product people, and Talent Acquisition. Check out all the roles here: https://zilliz.com/careers

If you're just starting out, I'd use sentence-transformers for calculating embeddings. You'll want a bi-encoder model since they produce embeddings. As the author of the blog, I'm partial towards Milvus (https://github.com/milvus-io/milvus) due to its enterprise and scale, but FAISS is a great option too if you're just looking for something more local and contained. Milvus will perform vector similarity search for you - all you need to do is give it a query vector.
In Introduction to vector similarity search (2022)
Milvus is completely open source (https://github.com/milvus-io/milvus) and supports a variety of index types (https://milvus.io/docs/overview.md#Index-types) and support various consistency levels, scalar/metadata filtering, and time travel. We started working on Milvus back in 2018, with 2.0 being released in January 2022 (https://github.com/milvus-io/milvus/releases/tag/v2.0.0). For those interested, here's a comparison with other open source vector databases: https://zilliz.com/comparison. For those who don't want to be burdened with installing and maintaining a local database, there's a managed service available as well: https://zilliz.com/cloud.

Solid work OpenAI, though I'd definitely like to see some more benchmarks on a wider variety of datasets in addition to the ones listed in the post. Regardless, it's good to see embeddings becoming more and more mainstream and easier to leverage out-of-box. We tried image embeddings many moons ago (2015) with AlexNet trained across a custom dataset, but we still had to add quite a few custom roles post-inference. A large selling point for ada-002 embeddings seems to be the reduced dimensionality. While lower-dimensional embeddings definitely help performance, I would say it's still highly dependent on the index that's being used. Graph- and tree-based indexes will benefit less than ones based on IVF (https://zilliz.com/blog/vector-index), as they do fewer overall distance computations during query time, but the speedup should still be sig

nificant. Still been meaning to try semantic search across Wikipedia via text embeddings. Will definitely play around with OpenAI + Milvus (https://github.com/milvus-io/milvus).
In New and Improved Embedding Model for OpenAI
Hashes are fine, but to say that "vectors are over" is just plain nonsense. We continue to see vectors as a core part of production systems for entity representation and recommendation (example: https://slack.engineering/recommend-api) and within models themselves (example: multimodal and diffusion models). For folks into metrics, we're building a vector database specifically for storing, indexing, and searching across massive quantities of vectors (https://github.com/milvus-io/milvus), and we've seen close to exponential growth in terms of total downloads. Vectors are just getting started.
