🧠 AgentMemory

Persistent memory for your OpenAI agents — store, recall, and forget.

---

The problem

Every OpenAI agent starts from zero. No memory of past conversations, preferences, decisions, or context. Every session is a blank slate.

AgentMemory solves this — giving your agent durable, queryable memory that persists across sessions.

---

Quickstart

Install dependencies:

pip install openai python-dotenv

Set your OpenAI API key:

# .env
OPENAI_API_KEY=your_key_here

Run your first memory session:

from agentmemory import AgentMemory

memory = AgentMemory(memory_path="agent_memory.json")

# Store memories from any text
memory.remember(
    "I am building a RAG application using Python and OpenAI. "
    "I prefer concise answers and clean code."
)

# Recall relevant memories
results = memory.recall("What is the user building?")
print(results)

Output:

Found 2 relevant memories:
  • [CONTEXT] User is building a RAG application using Python and OpenAI
  • [CONTEXT] User prefers concise answers and clean code

API Reference

memory = AgentMemory(
    memory_path="agent_memory.json",  # local storage file
    model="gpt-4o-mini",              # judge model
    max_memories=100,                 # max memories to store
)

memory.remember(text)        # extract and store memories from text
memory.recall(query, top_k)  # retrieve relevant memories
memory.forget(memory_id)     # delete a specific memory
memory.forget_all()          # clear all memories
memory.list_all()            # return all stored memories
memory.count                 # total number of memories

Streamlit demo

Run the interactive demo locally:

streamlit run app.py

Features:

• Store memories from any text input
• Search memories with semantic recall
• View all stored memories in the sidebar
• Delete individual memories or clear all

How it works

1. remember(text) sends the text to GPT-4o-mini which extracts individual factual claims, preferences, decisions, and context.
2. Each memory is stored as a structured object in a local JSON file.
3. recall(query) sends the query and all stored memories to GPT-4o-mini which scores each memory for relevance.
4. Memories are returned ranked by relevance score.

All storage is local — no cloud, no database, no infrastructure. Just a JSON file on your machine.

---

Cost

Each remember() call: ~$0.001

Each recall() call: ~$0.001

Both use GPT-4o-mini as the judge.

---

Roadmap

• Vector embedding search for faster recall at scale
• Memory expiry and TTL support
• Memory categories and filtering
• LangChain and LlamaIndex integration hooks
• Multi-agent shared memory support
