Kalindu Sekarage - PeerSpot reviewer
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.
Doug Meuross - PeerSpot reviewer
A reliable tool that offers good performance and is easy to use
I have had no issues with the stability of the product since it has always been a 100 percent reliable product and much better than the other databases available in the market. The multi-platform part is not good, especially when locked into things like Windows. You can judge your platform with Linux or Unix or whatever since they are good.

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."
"Robustness is the absolutely main feature."
"The product was easy to use."
"The documentation is very well written."
"I find the ease of deployment to be the most valuable aspect of this solution."
"I can deploy it on Linux, Mac OS, and Windows — it's very easy."
"The most valuable feature of Firebird SQL is the creation of databases."
"I like that we don't have to pay external fees to migrate this data. So, we are looking to relocate from Postgres or EDB."
"I appreciate the fact that, once the database is embedded, it doesn't need to be administered, and removes the requirement for a specific server."
 

Cons

"It would be beneficial if I could set a parameter and see different query mechanisms being run."
"It could be more accessible for handling larger data sets."
"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."
"The security of the users could improve in Firebird SQL."
"It would be nice to have a graphical user interface to handle the product."
"The solution could improve by providing partitioning and encryption. It is not at the higher level of database solution but it could be with some upgrades."
"I don't think the solution is very scalable, because the scalability of the performance when using more than one process is not very good."
"Technical support and performance could be better. We have some problems with this solution, but we don't know if the problem is with the database or the configuration. For example, sometimes, the users can't access the database."
"Database sharing is a capability that Firebird SQL lacks."
"Firebird SQL's performance has slowed since Firebird SQL 3 or 3.5 versions, where they developed over-the-wire encryption."
"On large databases, we have some difficulties."
 

Pricing and Cost Advice

"It is an open-source tool."
"Faiss is an open-source solution."
"I was using the free version of Firebird SQL."
"We are using the free solution, so there is no cost involved."
"It's open-source and free."
"It is a public domain system as every customer can install it on their system without paying any license fee."
"There is a yearly maintenance fee for the use of the solution."
"It is okay."
"The tool is open source."
"Firebird SQL is an open-source solution, which means it is a free product."
