Supermemory Pipecat SDK

Memory-enhanced conversational AI pipelines with Supermemory and Pipecat.

Installation

pip install supermemory-pipecat

Quick Start

import os
from pipecat.pipeline.pipeline import Pipeline
from pipecat.processors.aggregators.llm_context import LLMContext
from supermemory_pipecat import SupermemoryPipecatService

# Create memory service
memory = SupermemoryPipecatService(
    api_key=os.getenv("SUPERMEMORY_API_KEY"),
    user_id="user-123",  # Required: used as container_tag
    session_id="conversation-456",  # Optional: groups memories by session
)

# Use the universal LLM context supported by current Pipecat releases.
context = LLMContext([{"role": "system", "content": "You are a helpful assistant."}])
context_aggregator = llm.create_context_aggregator(context)

# Create pipeline with memory
pipeline = Pipeline([
    transport.input(),
    stt,
    context_aggregator.user(),
    memory,  # Automatically retrieves and injects relevant memories
    llm,
    transport.output(),
    context_aggregator.assistant(),
])

Configuration

Parameters

Parameter	Type	Required	Description
user_id	str	Yes	User identifier - used as container_tag for memory scoping
session_id	str	No	Session/conversation ID for grouping memories
api_key	str	No	Supermemory API key (or set SUPERMEMORY_API_KEY env var)
params	InputParams	No	Advanced configuration
base_url	str	No	Custom API endpoint

Advanced Configuration

from supermemory_pipecat import SupermemoryPipecatService

memory = SupermemoryPipecatService(
    user_id="user-123",
    session_id="conv-456",
    params=SupermemoryPipecatService.InputParams(
        search_limit=10,           # Max memories to retrieve
        search_threshold=0.1,      # Similarity threshold
        mode="full",               # "profile", "query", or "full"
        inject_mode="auto",        # "auto", "system", or "user"
        system_prompt="Based on previous conversations, I recall:\n\n",
    ),
)

Memory Modes

Mode	Static Profile	Dynamic Profile	Search Results
"profile"	Yes	Yes	No
"query"	No	No	Yes
"full"	Yes	Yes	Yes

How It Works

1. Intercepts context frames - Listens for Pipecat's universal LLMContextFrame (and legacy 0.x frames)
2. Tracks conversation - Separates real conversation messages from tagged memory context
3. Retrieves memories - Queries /v4/profile API with user's message
4. Injects memories - Uses a system message for audio/system mode and a tagged user message otherwise
5. Stores messages - Serializes newly observed user and assistant messages through a background queue that drains during cleanup

What Gets Stored

New user and assistant messages are stored as a JSON conversation segment. The injected <user_memories> message is filtered out before storage and does not advance the storage cursor.

For example, this conversation segment:

User: What's the weather like today?
Assistant: It's sunny today.

is sent to Supermemory as:

{
  "content": "[{\"role\": \"user\", \"content\": \"What's the weather like today?\"}, {\"role\": \"assistant\", \"content\": \"It's sunny today.\"}]",
  "container_tags": ["user-123"],
  "custom_id": "conversation-456",
  "metadata": { "platform": "pipecat" }
}
