Memory - Upsonic AI

Overview

What is Memory?

Memory gives your agents the ability to remember. Without memory, every conversation starts fresh - your agent doesn’t remember what you talked about before or who you are. With memory, your agents can:

Remember conversations - Reference previous messages and maintain context
Learn about users - Understand preferences, expertise level, and communication style
Improve over time - Build a complete picture of each user across all interactions
Reduce repetition - Never ask for the same information twice

How Memory Works

Memory works in two phases - before and after each conversation: Before Each Conversation:

Loads the user’s profile (if you’re using user analysis memory)
Retrieves the conversation summary (if you’re using summary memory)
Pulls up previous messages (if you’re using conversation memory)
Gives all this context to your agent automatically

After Each Conversation:

Saves the new messages to history
Updates the conversation summary
Analyzes what the agent learned about the user
Stores everything for next time

You don’t have to do anything - memory handles it all automatically.

Attributes

The Memory class provides the following key attributes:

from upsonic.storage import Memory, InMemoryStorage

memory = Memory(
    storage=storage,                    # Required: Storage backend
    session_id="session_123",          # Optional: For conversation/summary memory
    user_id="user_456",                # Optional: For user analysis memory
    full_session_memory=True,         # Enable complete chat history
    summary_memory=True,               # Enable conversation summaries
    user_analysis_memory=True,        # Enable user learning
    num_last_messages=10,             # Limit history to last N turns
    model="anthropic/claude-sonnet-4-5",            # Model for analysis/summaries
    user_profile_schema=UserProfile,  # Custom user profile schema
    dynamic_user_profile=True,        # Let agent create custom fields
    user_memory_mode='update',        # 'update' or 'replace' mode
    feed_tool_call_results=False,     # Include tool calls in memory
    debug=True                        # Enable debug logging
)

Choosing Right Memory Types

What is The Selection Criteria?

Choose memory types based on your specific needs:

Memory Type	When to Use	Requirements
Conversation Memory	Customer support, tutoring, detailed conversations	`session_id`
Summary Memory	Long conversations, cost reduction	`session_id`, `model`
User Analysis Memory	Personalization, user preferences	`user_id`, `model`

Making Combination of Memory

You can use one type or combine all three for the most powerful memory system:

# Basic conversation memory only
memory = Memory(
    storage=InMemoryStorage(),
    session_id="session_001",
    full_session_memory=True
)

# All three memory types
memory = Memory(
    storage=InMemoryStorage(),
    session_id="session_001",
    user_id="user_001",
    full_session_memory=True,
    summary_memory=True,
    user_analysis_memory=True,
    model="anthropic/claude-sonnet-4-5"
)

Use Case for Conversation Memory

Customer Support: Maintain context across support tickets
Tutoring: Remember what topics have been covered
Long Conversations: Keep track of detailed discussions
Debugging Sessions: Remember error states and solutions

Use Case for Summary Memory

Long Sessions: Reduce token costs for very long conversations
Meeting Notes: Automatically summarize key points
Documentation: Create evolving summaries of complex topics
Cost Optimization: Maintain context without full history

Use Case for User Analysis Memory

Personalization: Adapt responses to user preferences
Learning Systems: Track user progress and expertise
Customer Profiles: Build comprehensive user understanding
Adaptive Interfaces: Customize experience based on user traits

Examples

Basic Memory Example

About Example Scenario

This example demonstrates a customer support agent that remembers conversations and learns about users across multiple sessions. The agent will maintain context within each support session and build a profile of each customer for personalized service.

Memory Configuration

from upsonic.storage import Memory, SqliteStorage

# Create persistent storage
storage = SqliteStorage(
    sessions_table_name="support_sessions",
    profiles_table_name="customers",
    db_file="./support_memory.db"
)

# Create memory for customer support
memory = Memory(
    storage=storage,
    session_id="support_session_001",
    user_id="customer_123",
    full_session_memory=True,      # Remember conversation history
    user_analysis_memory=True,     # Learn about the customer
    num_last_messages=10,          # Keep last 10 turns for context
    model="anthropic/claude-sonnet-4-5"
)

Full Code

from upsonic import Agent, Task
from upsonic.storage import Memory, SqliteStorage

# Create persistent storage
storage = SqliteStorage(
    sessions_table_name="support_sessions",
    profiles_table_name="customers",
    db_file="./support_memory.db"
)

# Create memory for customer support
memory = Memory(
    storage=storage,
    session_id="support_session_001",
    user_id="customer_123",
    full_session_memory=True,      # Remember conversation history
    user_analysis_memory=True,     # Learn about the customer
    num_last_messages=10,          # Keep last 10 turns for context
    model="anthropic/claude-sonnet-4-5"
)

# Support agent
agent = Agent(
    model="anthropic/claude-sonnet-4-5",
    name="Support Agent",
    memory=memory
)

# Conversation 1
task1 = Task(description="I'm having trouble logging in to my account")
result1 = agent.do(task1)
print("Response 1:", result1)

# Conversation 2 - agent remembers context and user
task2 = Task(description="I tried resetting my password but didn't receive the email")
result2 = agent.do(task2)
print("Response 2:", result2)

# Next session - agent remembers customer history
memory_new_session = Memory(
    storage=storage,
    session_id="support_session_002",  # New session
    user_id="customer_123",            # Same customer
    full_session_memory=True,
    user_analysis_memory=True,         # Loads existing profile
    model="anthropic/claude-sonnet-4-5"
)

agent_new = Agent(model="anthropic/claude-sonnet-4-5", memory=memory_new_session)
task3 = Task(description="Hello, I'm back")
result3 = agent_new.do(task3)  # Agent knows customer's previous issues
print("Response 3:", result3)

This example shows how the agent:

Remembers the conversation - References previous login issues
Learns about the user - Builds a profile of the customer’s technical level and preferences
Maintains context - Knows about password reset attempts from earlier in the session
Persists across sessions - Recognizes the customer in a new session and recalls their history
