Choose turbovec if…
- License: turbovec is MIT, pgvecto.rs is Apache-2.0.
- Tags unique to turbovec: ann, avx512, embedding, embeddings.
- - Use turbovec when you need to save substantial amounts of memory; for instance, a 10 million document corpus can fit in 4 GB RAM instead of the typical 31 GB with float32.
When NOT to use turbovec
- - Avoid using turbovec in environments where the hardware architecture does not support specific SIMD instructions (like NEON on ARM and AVX-512BW on x86), as this can lead to performance degradation.
- - Do not use it if your application requires external managed services for vector indexing, as turbovec is designed for local deployments without data leaving the machine or VPC.
- - Avoid if you require high precision beyond what 4-bit quantization (or lower bit-widths depending on the configuration) offers.
- - Refrain from using turbovec in scenarios where the lack of a training phase leads to suboptimal performance, as it might not adapt well to certain datasets that benefit from such pre-processing.
Choose pgvecto.rs if…
- License: pgvecto.rs is Apache-2.0, turbovec is MIT.
- Tags unique to pgvecto.rs: chatgpt, gpt, hacktoberfest, llm.
- Need integration with PostgreSQL for vector searches
When NOT to use pgvecto.rs
- Preferring a database system without PostgreSQL dependencies
- Looking for a standalone solution, as pgvecto.rs is a PostgreSQL extension
