VerifiedAn agent's memory includes short-term memory (conversational context window, typically 4K–128K tokens), long-term memory (vector database), and procedural memory (intermediate state cache for tool calls).75% similarUnverifiedClaude's Projects and ChatGPT's Memory features attempt to alleviate context limitations through persistent memory, but are limited to the single-user dimension and cannot be shared across users.73% similarVerifiedThe mainstream solutions for long-term memory mechanisms fall into three categories: externalized storage, structured memory files, and memory distillation.71% similarUnverifiedWhen memory scales to hundreds of MB or even GB, a pure file-based approach may still need to be combined with indexing mechanisms and vector retrieval technologies to balance simplicity and performance70% similar
