Integration improves accuracy and supports token-level embedding
The best features FAISS offers for my team include seamless integration with Colbert and the ability to use FAISS via the Ragatouille framework, which is tailor-made for using the Colbert model. Feature-wise, FAISS allows for more accurate result retrieval, and retrieval speed is also good when comparing the index size. Regarding features, I also emphasize that the usability of FAISS is very seamless, particularly its integration with Colbert and Ragatouille. FAISS has positively impacted my organization by helping us increase the accuracy of retrieval documents; when we store documents in token-level embedding, the accuracy will be high. Additionally, we do not need any external server to host FAISS, allowing us to integrate it with our backend framework, making it a very flexible framework.

AI Solutions Lead at ADP
Semantic search has transformed client sites and drives faster projects with higher conversions
Adapting to Supabase Vector was relatively smooth, but there was definitely a moderate learning curve at the start. The SQL foundation, REST API, documentation, and integration with all the AI tools made it easier. However, understanding embeddings, index types, similarity metrics, and how SQL and vector hybrid queries work, as well as the RLS policies for vectors, required some time to learn. I do not have many things to point out, but a couple of areas for improvement come to mind. For index optimization guidance, clearer instructions on when to use IVFFlat versus HNSW indexes would be helpful. Additionally, having a built-in embedding generation capability would simplify the workflow, as currently, I use external services such as OpenAI or Hugging Face for that purpose.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The product has better performance and stability compared to one of its competitors."
"I used Faiss as a basic database."
"Supabase Vector rapidly increases the speed and efficiency with which I search through a database, helping with my data analysis tasks."
"Supabase Vector positively impacts my organization by reducing the cost of the LLMs."
"Supabase Vector positively impacts my organization through major improvements in search relevance, faster development speed, a simpler architecture, and reduced engineering overhead, with better performance in real queries due to the hybrid SQL plus vector search."
"Supabase Vector is easy to set up and cost-effective because the alternative is Firebase, which requires a credit card."
"Previously, 50% of searches returned no results or irrelevant products, but we changed that to 90% of searches returning relevant results, which led to a 30% increase in search-to-purchase conversions for the e-commerce client and was a big win for us."
"Supabase Vector has made my work a lot easier, especially since we already use PostgreSQL instances on Supabase for our relational database."
"Using Supabase Vector, I was able to set it up in a couple of days, got it validated, and started working on building up the algorithm on top of that."
"Supabase enables us to lower the skill floor while keeping the ceiling high."
 

Cons

"One of the drawbacks of Faiss is that it works only in-memory. If it could provide separate persistent storage without relying on in-memory, it would reduce the overhead."
"It could be more accessible for handling larger data sets."
"It would be beneficial if I could set a parameter and see different query mechanisms being run."
"When setting up a database, a PostgreSQL instance, which is the most popular use of Supabase, instead of having to go and write and run an SQL line to create a pgvector on Supabase, it would be nice if the person creating the database for the project could just be asked with maybe a checkbox whether they want a vector database or not."
"I feel Supabase Vector can be improved by venturing further into adding more backend features and maybe working with fast API frameworks like Python languages; they could improve and widen their capabilities."
"For advanced production use with millions of embeddings, it's necessary to be thoughtful about indexing such as HNSW or IVFFlat and hardware sizing to keep query times fast."
"My experience with Supabase Vector's performance at scale indicates that it operates excellently at small scales, but as we move toward larger scales, such as multi-million vectors, it requires careful engineering to maintain predictable performance, with challenges such as query plan complexity and latency variance."
"It would be nice if all of this could be integrated all in one place with Supabase."
"I think the support system can be better because after Supabase Vector stopped working in India, there is no support."
"Adapting to Supabase Vector was relatively smooth, but there was definitely a moderate learning curve at the start."
"I notice that the schema visualizer can be improved. Additionally, the internal AI assistant powered by GPT can also be improved."
