LightMem is a lightweight Python framework for adding long-term memory to LLM applications and AI agents, providing memory storage, retrieval, and update mechanisms. It works with cloud APIs (OpenAI, DeepSeek) and local model servers (Ollama, vLLM).

Use cases

• add long-term memory to an llm chatbot
• remember user preferences across conversations
• build a personalized ai agent with memory
• store and retrieve conversation history for llms
• give my agent persistent memory without heavy infrastructure
• manage memory for llm applications

When to choose

• you want a lightweight, easy-to-integrate memory layer for LLM apps
• you need flexible backend support for cloud and local models
• you want a research-backed memory framework with active development

When to avoid

• you need a full production memory platform with enterprise features
• you need multimodal or highly structured memory out of the box
• you require a non-Python stack
