Maximem Synap's Agent Memory Now Available for AutoGen

AutoGen is Microsoft's framework for building multi-agent applications. Research-grade orchestration. Conversable agents. Structured dialogue patterns. If you are building agents that need enterprise-grade coordination or academic rigor, AutoGen is where you start.

Today, Maximem Synap extends AutoGen with persistent per-user memory. Native context management stores conversation state within a single process. Synap makes that state survive restarts, resolve entities across sessions, and retrieve relevant context without manual wiring.


Where AutoGen Excels

AutoGen taught developers how to build structured agent conversations. Group chats with managed turn-taking. Nested agent hierarchies. Human-in-the-loop approval points. If your system needs multiple agents to negotiate, delegate, or reach consensus under controlled conditions, AutoGen handles the dialogue orchestration well.

The problem emerges when your user returns after a day or a week. AutoGen's context options handle the current conversation. They do not persist across process restarts. Structured orchestration does not help if the agent forgets what the user told it yesterday.


How AutoGen Memory Works Today

AutoGen ships context management patterns for conversation tracking. All store data within a single process lifetime. For a deeper look at how each works, see the AutoGen documentation.

ChatCompletionContext stores every message in a list attached to the agent run. This scratchpad grows with each turn. After twenty exchanges, your context window fills with accumulated noise. The agent struggles to find your actual instructions. When the process restarts, the list clears. Every session begins at zero.

BufferedChatCompletionContext keeps only the most recent K messages and discards older content. The window slides forward. Conversations from yesterday are already gone. This approach does not solve memory. It accelerates forgetting by design.

Both options solve in-session state management. Cross-session persistence, entity resolution, semantic retrieval, and automatic compaction fall outside their scope. These are memory-layer problems, not framework-level concerns.


What Synap Adds

Synap is agentic context management. It does not replace AutoGen's context system. It extends the framework with persistent memory agents can invoke as tools.

We ship two BaseTool implementations:

Search tool performs semantic search over user-scoped memories. Accepts a query and optional result limit. Returns ranked memory objects the agent can reason over.

Store tool ingests new facts into Synap. Takes content and optional metadata. Returns a status identifier confirming persistence.

Register both tools with any AutoGen agent. The agent decides when to recall prior context and when to save new facts. Scope is set at tool initialization via user_id and optional customer_id. The agent only sees query and content arguments.

The integration is a native package. Register two tools. Your agents start remembering without a rewrite.

We built this because structured agents kept stalling in production. The problem was not bad orchestration. It was missing context that lived in a different session last Tuesday. Production testing hit 90.2% on LongMemEval. Typical recall returns in under 100ms.

For why context management is infrastructure and not a feature, read What Is Agentic Context Management?. For build-versus-buy numbers, see The Real Cost of DIY Agent Memory.


Technical Deep Dive

LongMemEval Benchmark

LongMemEval tests whether agents recall facts across long, multi-turn conversations spanning multiple sessions. The benchmark simulates production conditions where users return days apart and expect the agent to remember prior context. Synap scores 90.2% on this benchmark. Baseline vector-only approaches typically score 60-70%. The gap comes from entity resolution and temporal awareness that pure vector search lacks.

Entity Resolution Mechanism

Synap tracks identity across 15 reference patterns: names, emails, phone numbers, account IDs, session IDs, device IDs, and more. When an agent encounters "John" in one session and "[email protected]" in another, the resolution engine runs deterministic matching on structured fields, then probabilistic matching on unstructured references. Conflicts are resolved using temporal recency and source confidence scores. The result is a single canonical entity that accumulates context across all identifiers.

Accuracy-Preserving Compaction

Compaction identifies which facts are critical versus redundant. Critical facts include user preferences, constraints, commitments, and entity relationships. Redundant facts include repeated greetings, acknowledged statements, and intermediate reasoning steps. The compaction engine uses a classifier trained on conversation data to distinguish these categories. In Maximem's internal production testing, most integrations see 60 to 70% fewer tokens shipped to the LLM per turn after compaction kicks in. The accuracy preservation comes from never dropping classified-critical facts, even under aggressive token budgets.

Graph Traversal in Accurate Mode

Fast mode retrieves by vector similarity alone. Accurate mode adds a graph layer that traverses relationships between entities. If you ask about "the project John mentioned," the graph finds John, traverses to projects linked to John, and returns the relevant context. This adds latency but catches connections that vector similarity misses. Reranking then scores results by recency, confidence, and query relevance.

Multi-Tenant Scoping

Memory is scoped by three keys: user_id identifies the person, conversation_id isolates individual sessions, and customer_id enables multi-tenant deployments. A SaaS deploying agents for multiple customers uses customer_id to ensure tenant A never sees tenant B's memory. This scoping is enforced at the storage layer, not just in application logic.

For the AutoGen integration, scope is set per tool instance. Register fresh tool instances for each user session in multi-tenant setups. This pairs Synap's storage-level scoping with AutoGen's agent-level tool isolation.


What Synap Adds to AutoGen

Persistence

AutoGen Native. In-process only. State clears on restart. With Synap. Per-user memory survives across sessions and restarts.


Entity Resolution

AutoGen Native. Raw identifiers. No linking across sessions. With Synap. "John" and "[email protected]" resolve to one canonical entity across every session.


Compaction

AutoGen Native. Manual summarization or no compaction. Lossy. With Synap. Automatic and configurable. Accuracy-preserving compaction that does not drop critical facts.


Retrieval Latency

AutoGen Native. Depends on setup. With Synap. Typical recall via the search tool returns in under 100ms.


Long-Term Recall

AutoGen Native. Not benchmarked for cross-session recall. With Synap. 90.2% on LongMemEval.


Failure Handling

AutoGen Native. Unhandled tool or retrieval errors propagate and abort the run. With Synap. Read failures return empty results and a logged error. Write failures raise SynapIntegrationError so you know persistence missed. Your agent keeps running.


User Scoping

AutoGen Native. Session-scoped only. With Synap. user_id and optional customer_id set per tool instance. Fresh tool registration per session for multi-tenant isolation.


What Production Teams Gain

Cross-session continuity. Your user chats on Monday, returns on Wednesday. The search tool recalls prior context. The store tool persists new facts the agent learns. The agent treats every session as one continuous conversation. Native memory treats every session as a fresh start.

Accuracy that ships. 90.2% on LongMemEval measures whether agents recall facts across long, multi-turn conversations spanning multiple sessions. This benchmark tests the specific failure mode that breaks production agents: accurate recall over distance and time.

Token efficiency. Synap's compaction trims conversation history without dropping critical context. Most teams see 60 to 70% fewer tokens shipped to the LLM per turn. At scale, that is the difference between profit and burn.

Latency that does not block. Typical recall via the search tool returns in under 100ms. Store tool ingestion runs asynchronously and does not block agent execution. A failure returns empty results and a log line, not a broken agent.

Entity resolution. "John from Acme," "[email protected]," and "user_4829" resolve to one person across every session. Synap handles this at the memory layer so your agent does not have to.

Production resilience. Read failures return empty results and a logged error instead of crashing the agent. Write failures raise SynapIntegrationError so you know if persistence missed. Both tools implement standard AutoGen BaseTool interfaces.


How to Get Started

Three steps. No rearchitecture.

Step 1: Install

pip install maximem-synap-autogen autogen

Step 2: Initialize and register

import os from maximem_synap_autogen import MaximemSynapSDK, SynapSearchTool, SynapStoreTool from autogen import ConversableAgent 
sdk = MaximemSynapSDK(api_key=os.getenv("SYNAP_API_KEY"))

Create scoped memory tools for this user

search_tool = SynapSearchTool(sdk=sdk, user_id="user_123") store_tool = SynapStoreTool(sdk=sdk, user_id="user_123")

Register with any AutoGen agent

agent = ConversableAgent( name="support_agent", llm_config={"model": "gpt-4", "api_key": os.getenv("OPENAI_API_KEY")}, tools=[search_tool, store_tool], system_message=""" Use synap_search to recall prior context before answering. Use synap_store to save new facts the user provides. """ )

Step 3: Deploy

For multi-tenant production, register fresh tool instances per user session. This ensures tenant isolation at the agent level. Synap handles persistence,
compaction, and retrieval. Your agent handles orchestration.

Memory Is Infrastructure

AutoGen gave developers a framework for structured multi-agent conversations. The context layer it ships handles in-session state well. Making that state persist across sessions, resolve entities, and retrieve intelligently is a different layer of the stack.

The teams that ship production agents discover this around month three. They either build memory infrastructure themselves, or they plug in a system built for the problem.

Memory is infrastructure, not a feature.
