31 rijin_r 11 8/23/2025, 6:31:00 AM github.com ↗
OctaneDB is an open-source vector database for Python that focuses on ultra-fast similarity search for high-dimensional data—perfect for AI/ML, semantic search, and large-scale document or embedding retrieval.
What does it do?
Store, index, and search millions of embeddings (text, images, etc.) with sub-millisecond query time.
Supports in-memory and efficient HDF5 persistent storage.
Integrates seamlessly with sentence-transformers for automatic text embedding.
Key Features:
10x faster than Pinecone or ChromaDB for vector search and batch insertions.
Advanced indexing: HNSW (approximate nearest neighbor), FlatIndex
Batch search, advanced metadata filtering, GPU acceleration
Update: Looking through your code, I already found within 5 minute flaws, since it is obvious that you have not written it (looking at your past work, I doubt you even understand what it does), I will not even point the issues out.
Just take 10 minutes to write something that explains the project.
As soon as I see this README I assume the code is generated(worthless) as well
- Don't judge a book by it's cover
- Don’t give your book a shit cover because it will put people off.
Please get more experience and use AI less. It's not a good look, and if it's vibe coded it's not your code anyway, it's just you asking somebody else to do it (at best). You don't want to be an expert in asking others to do your work.
Best of luck on your turn around.
