## Choose when

### Choose infinity if…

- infinity is primarily C++; mempalace is Python.
- License: infinity is Apache-2.0, mempalace is MIT.
- Mempalace and Infinity are alternative solutions in the space of AI memory systems, both providing high-performance indexing and retrieval capabilities suitable for LLM applications.
- Tags unique to infinity: cpp20, full-text-search, embedding, ai-native.
- Infinity should be considered when developing LLM applications that require low latency and high query per second performance for a mix of data types including full-text, dense/sparse embeddings, and

### Choose mempalace if…

- mempalace is primarily Python; infinity is C++.
- License: mempalace is MIT, infinity is Apache-2.0.
- Mempalace and Infinity are alternative solutions in the space of AI memory systems, both providing high-performance indexing and retrieval capabilities suitable for LLM applications.
- Tags unique to mempalace: memory, llm, ai, python.
- mempalace ships Docker support for self-hosted deployment.
- - You require local storage for conversation history and want to avoid cloud dependencies.

## When NOT to use infinity

- Avoid Infinity if your application primarily deals with traditional relational or NoSQL databases where structured queries are more critical than hybrid search capabilities.
- If your project does not need the versatility to handle diverse data types like vectors, tensors, and full text simultaneously, or if high-speed query performance is not a priority, Infinity may be an
- Consider alternative solutions over Infinity if real-time, on-the-fly adaptation for retrieval-augmented generation (RAG) systems isn't critical for your application's success.

## When NOT to use mempalace

- - When requiring real-time collaboration across multiple devices, as MemPalace is focused on local storage.
- - If your project strictly requires cloud-based solutions for ease of deployment and scalability.
