However, if You become 237 | compliant, then the rights granted under this License from a particular 238 | Contributor are reinstated (a) provisionally, unless and until such 239 | Contributor explicitly and finally terminates Your grants, and (b) on an 240 | ongoing basis, if such Contributor fails to notify You of the 241 | non-compliance by some reasonable means prior to 60 days after You have 242 | come back into compliance. Moreover, Your grants from a particular 243 | Contributor are reinstated on an ongoing basis if such Contributor 244 | notifies You of the non-compliance by some reasonable means, this is the 245 | first time You have received notice of non-compliance with this License 246 | from such Contributor, and You become compliant prior to 30 days after 247 | Your receipt of the notice. 248 | 249 | 5.2. If You initiate litigation against any entity by asserting a patent 250 | infringement claim (excluding declaratory judgment actions, 251 | counter-claims, and cross-claims) alleging that a Contributor Version 252 | directly or indirectly infringes any patent, then the rights granted to 253 | You by any and all Contributors for the Covered Software under Section 254 | 2.1 of this License shall terminate. 255 | 256 | 5.3. In the event of termination under Sections 5.1 or 5.2 above, all 257 | end user license agreements (excluding distributors and resellers) which 258 | have been validly granted by You or Your distributors under this License 259 | prior to termination shall survive termination. 260 | 261 | ************************************************************************ 262 | * * 263 | * 6.

🧠 GPT Memory

Memory Driven Reasoning for Smarter AI Agents

9 | 10 | GPT Memory is a library powered by Tovana that introduces a new approach to improving LLM reasoning through actionable insights (aka beliefs) derived from continuous interactions and long term memory. 11 | 12 | [![PyPI version](https://img.shields.io/pypi/v/tovana?logo=pypi&logoColor=white&style=flat)](https://badge.fury.io/py/tovana) 13 | [![License: Apache 2](https://img.shields.io/badge/License-Apache-yellow.svg)](https://opensource.org/license/apache-2-0) 14 |
15 | 16 | ## 🤔 Why GPT Memory? 17 | 18 | Current LLMs face significant limitations in their ability to learn and adapt from user-specific interactions over time. While LLMs excel at processing vast amounts of data, they struggle with ongoing personalization and context-aware learning. This gap restricts their ability to provide truly adaptive and evolving AI experiences. 19 | 20 | Our Memory manager aims to address these challenges by providing a comprehensive memory and belief management framework for AI agents. Its core concept revolves around converting experiences (events) into memories, which in turn shape beliefs. These beliefs then influence the agent's reasoning, responses, and actions. 21 | 22 | By simulating human-like memory processes, GPT Memory enables more personalized, adaptive, and context-aware AI interactions. This framework bridges the gap between static knowledge bases and dynamic, experience-based learning, allowing AI agents to evolve their understanding and behavior over time. 23 | 24 | ## 🚀 Quick Start 25 | 26 | 1. Install Tovana: 27 | ```bash 28 | pip install tovana 29 | ``` 30 | 31 | 2. Use it in your project: 32 | 33 | ```python 34 | from tovana import MemoryManager 35 | 36 | business_description = "a commerce shopping assistant" 37 | 38 | # Initialize with your preferred LLM provider and API key (Refer to the documentation for specific models) 39 | memory_manager = MemoryManager(api_key="provider-api-key", 40 | provider="openai", 41 | business_description=business_description, 42 | include_beliefs=True) 43 | ``` 44 | 45 | 3. Manage your LLMs memory with ongoing user conversation messages: 46 | ```python 47 | user_id = "user123" 48 | message = "I just moved from New York to Paris for work." 49 | 50 | # Update user memory 51 | memory_manager.update_user_memory(user_id=user_id, message=message) 52 | print(user_memory) # Output: {'location': 'Paris', 'previous_location': 'New York'} 53 | 54 | # Get memory context for LLM 55 | context = memory_manager.get_memory_context(user_id=user_id) 56 | print(context) # Output: 'User Memory:\n location: Paris,\n previous_location: New York' 57 | 58 | # Get beliefs 59 | beliefs = memory_manager.get_beliefs(user_id=user_id) 60 | print(beliefs) # Output: {"beliefs": "- Provide recommendations for products shipping to Paris"} 61 | ``` 62 | 63 | ## 🏗️ Architecture 64 | Screenshot 2024-08-21 at 9 04 07 65 | 66 | ## 🧠 Belief Generation 67 | 68 | GPT memory introduces a new approach to LLM reasoning: actionable beliefs generated from user memory. These beliefs provide personalized insights that can significantly enhance your agent's planning, reasoning and responses. 69 | 70 | ### Examples 71 | #### Input: 72 | - `business_description`: "a commerce site" 73 | - `memory`: {'pets': ['dog named charlie', 'horse named luna']} 74 | #### Output: 75 | 76 | ```json 77 | {"beliefs": ",- suggest pet products for dogs and horses"} 78 | ``` 79 | 80 | #### Input: 81 | 82 | - `business_description`: "an AI therapist" 83 | - `memory`: {'pets': ['dog named charlie', 'horse named luna', 'sleep_time: 10pm']} 84 | #### Output: 85 | 86 | ```json 87 | {"beliefs": ",- Suggest mediation at 9:30pm\n- Suggest spending time with Charlie and Luna for emotional well-being"} 88 | ``` 89 | 90 | ## 🌟 Features 91 | 92 | | Feature | Status | Description | 93 | |----------------------------------|-------------|---------------------------------------------------------------------------------------------| 94 | | 🧠 Human-like Memory | ✅ | Transform interactions into lasting memories and actionable beliefs | 95 | | 🔍 Smart Information Extraction | ✅ | Automatically capture and store relevant user details from conversations | 96 | | 💡 Dynamic Belief Generation | ✅ | Create personalized, context-aware insights to guide AI responses | 97 | | 🤖 LLM-Friendly Context | ✅ | Seamlessly integrate memory and beliefs into your AI's decision-making process | 98 | | 🔌 Easy Integration | ✅ | Plug into your AI applications with a straightforward API | 99 | | 🎭 Conflict Resolution | ✅ | Intelligently handle contradictions in user information | 100 | | 🌐 Flexible Architecture | ✅ | Designed to work with various LLM providers and models | 101 | | 📊 Memory Management | ✅ | Process events, store short-term and long-term memories, and manage beliefs | 102 | | 🔗 Advanced Association Creation | ✅ | Form connections between memories and beliefs for more nuanced understanding | 103 | | 🧵 Async Functionality | ✅ | Support for asynchronous operations to enhance performance in concurrent environments | 104 | | ⛁ Persistent Database Support | 🔜 | Integration with persistent databases for long-term storage and retrieval of memory data | 105 | | 🎛️ Custom Belief Generation | 🔜 | User-generated beliefs offering end-to-end flexibility in shaping the belief system reasoning| 106 | 107 | ## 🛠️ API Reference 108 | 109 | ### MemoryManager 110 | 111 | - `get_memory(user_id: str) -> JSON`: Fetch user memory 112 | - `delete_memory(user_id: str) -> bool`: Delete user memory 113 | - `update_memory(user_id: str, message: str) -> JSON`: Update memory with relevant information if found in message 114 | - `batch_update_memory(user_id: str, messages: List[Dict[str, str]]) -> JSON`: Update memory with relevant information if found in message 115 | - `get_memory_context(user_id: str, message: Optiona[str]) -> str`: Get formatted memory context, general or message specific 116 | - `get_beliefs(user_id: str) -> str`: Get actionable beliefs context 117 | 118 | ### Batch Update Memory 119 | Traditional per-message memory updates can be costly and inefficient, especially in longer conversations. They often miss crucial context, leading to suboptimal information retrieval. 120 | 121 | Our batch memory update method addresses these challenges by processing entire conversations at once. This approach not only improves performance and reduces costs but also enhances the quality of extracted information. This results in a more coherent and accurate user memory, ultimately leading to better AI reasoning. 122 | 123 | #### Example 124 | 125 | ```python 126 | user_id = "user123" 127 | messages = [ 128 | {"role": "user", "content": "Hi, I'm planning a trip to Japan."}, 129 | {"role": "assistant", "content": "That's exciting! When are you planning to go?"}, 130 | {"role": "user", "content": "I'm thinking about next spring. I love sushi and technology."} 131 | ] 132 | 133 | await memory_manager.batch_update_memory(user_id, messages) 134 | ``` 135 | 136 | ### Sync vs Async Updates 137 | This library provides both synchronous and asynchronous update methods to cater to different use cases and application architectures: 138 | 139 | 1. **Asynchronous Updates (`AsyncMemoryManager`)**: Ideal for applications built on asynchronous frameworks like FastAPI or asynchronous Python scripts. This allows for non-blocking memory updates, improving overall application performance, especially when dealing with I/O-bound operations or high-concurrency scenarios. 140 | 2. **Synchronous Updates (`MemoryManager`)**: Suitable for traditional synchronous applications or when you need to ensure that memory updates are completed before proceeding with other operations. This can be useful in scripts or applications where the order of operations is critical. 141 | 142 | By providing both options, our library offers flexibility, allowing to choose the most appropriate method based on your specific application requirements and architecture. 143 | 144 | ## 🤝 Contributing 145 | 146 | We welcome contributions!

Reasoning: A Heuristic Approach to Enhancing AI Agents with Dynamic Belief Systems 2 | 3 | ## Abstract 4 | 5 | Current AI memory systems face significant limitations in mimicking human-like intelligence, including their static nature, lack of contextual understanding, and inability to form beliefs or learn from experiences. This paper introduces Memory Driven Reasoning, a novel heuristic approach to augment AI agents with a comprehensive memory and belief management framework. By simulating human-like memory processes, our system enables more personalized, adaptive, and context-aware AI interactions. We present the architecture, key components, and implementation details of our system, demonstrating its potential to bridge the gap between static knowledge bases and dynamic, experience-based learning. Our preliminary results suggest that this approach can enhance the reasoning capabilities of large language models (LLMs) in a manner similar to chain-of-thought prompting. 6 | 7 | ## 1. Introduction 8 | 9 | Large language models (LLMs) have made significant strides in natural language processing tasks, but they still struggle with maintaining context over long conversations and adapting to user-specific information. Traditional approaches using vector databases or semantic search lack the ability to form beliefs, handle contradictions, or selectively retain information. To address these limitations, we propose Memory Driven Reasoning, a heuristic system designed to enhance AI agents with human-like memory processes and belief formation. 10 | 11 | Recent work by Wei et al. (2022) has shown that chain-of-thought prompting can significantly improve the reasoning capabilities of LLMs [4]. Our approach builds upon this idea by incorporating a dynamic memory system that allows for the formation and updating of beliefs over time, potentially enabling more sophisticated reasoning chains. 12 | 13 | ## 2. Related Work 14 | 15 | Recent advancements in memory systems for LLMs have shown promising results in enhancing their capabilities: 16 | 17 | ### 2.1 MemoryBank 18 | 19 | Zhong et al. (2024) introduced MemoryBank, a novel memory mechanism for LLMs that enables models to recall relevant memories, continuously evolve through memory updates, and adapt to a user's personality over time[1]. MemoryBank incorporates a memory updating mechanism inspired by the Ebbinghaus Forgetting Curve theory, allowing for more human-like memory retention and forgetting. 20 | 21 | ### 2.2 Offline Reinforcement Learning 22 | 23 | Levine (2022) proposed using offline reinforcement learning (RL) to leverage the knowledge about human behavior contained within language models[2]. This approach allows for optimizing reward functions that depend on downstream behavior of human users, potentially leading to more effective goal-directed interactions. 24 | 25 | ### 2.3 Memory-Efficient LLMs 26 | 27 | Recent research has focused on reducing the memory requirements of LLMs through various techniques, including: 28 | - Recomputing activations over sets of layers 29 | - Trading increased computation for reduced memory use 30 | - Efficient memory reuse through compiler optimizations[3] 31 | 32 | ### 2.4 Chain-of-Thought Prompting 33 | 34 | Wei et al. (2022) demonstrated that prompting LLMs to generate step-by-step reasoning before producing a final answer significantly improves their performance on complex reasoning tasks [4]. This approach, called chain-of-thought prompting, suggests that LLMs have latent reasoning capabilities that can be activated through appropriate prompting. 35 | 36 | ## 3. System Architecture 37 | 38 | Our Memory Driven Reasoning system consists of several key components: 39 | 40 | ### 3.1 Event Handler 41 | Captures and preprocesses incoming events from the agent's environment, extracting relevant information and metadata. 42 | 43 | ### 3.2 Memory Gateway 44 | Acts as a filter and router for incoming processed events, directing them to appropriate memory stores based on predefined rules. 45 | 46 | ### 3.3 Short-Term Memory (STM) 47 | Stores recent events and information relevant to the current session, implementing a decay mechanism to gradually remove less relevant information. 48 | 49 | ### 3.4 Long-Term Memory (LTM) 50 | Stores persistent memories and knowledge acquired over time, organized using efficient data structures such as graph databases. 51 | 52 | ### 3.5 Beliefs System 53 | Manages a collection of beliefs derived from memories, categorized as public or private, and implements belief update mechanisms. 54 | 55 | ### 3.6 Memory CRUD 56 | Creates and manages associations between memories, beliefs, and emotions, supporting multi-dimensional associations. 57 | 58 | ### 3.7 Context Retrieval 59 | Utilizes the Belief System, STM, and LTM to inform decision-making processes and generate optimal context information for user queries. 60 | 61 | ## 4. Implementation 62 | 63 | We implemented our system using Python, leveraging the Tovana library for memory management. Key classes include: 64 | 65 | - MemoryManager: Handles memory operations, including updates, retrievals, and belief generation. 66 | - AsyncMemoryManager: Provides asynchronous memory management for improved performance in concurrent environments. 67 | - BaseMemoryManager: Defines the core functionality for memory management, including LLM integration and business logic. 68 | 69 | Our implementation incorporates ideas from MemoryBank[1] for continuous memory evolution and the offline RL approach[2] for optimizing user interactions. 70 | 71 | ## 5. Graph-Based Approach 72 | 73 | Our system utilizes graph databases to model beliefs as interconnected nodes, enabling advanced aggregations and hierarchical layers of composite beliefs. This approach allows for: 74 | 75 | - Efficient storage and querying of interconnected data 76 | - Application of graph algorithms for deeper insights 77 | - Weighted edges to represent the importance of beliefs 78 | - Reversible edges for understanding dependency flows 79 | 80 | ## 6. Experimental Results 81 | 82 | We conducted experiments comparing our Memory Driven Reasoning system to traditional approaches, recent memory-enhanced LLMs, and chain-of-thought prompting: 83 | 84 | ### 6.1 Experimental Setup 85 | 86 | We evaluated our system on a range of reasoning tasks, including arithmetic word problems, commonsense reasoning, and multi-step logical deduction. We compared the performance of: 87 | 88 | 1. A baseline LLM without additional memory or reasoning enhancements 89 | 2. The same LLM with chain-of-thought prompting 90 | 3. Our Memory Driven Reasoning system 91 | 92 | ### 6.2 Metrics 93 | 94 | We measured performance using the following metrics: 95 | 96 | - Accuracy: The proportion of correct answers across all tasks 97 | - Reasoning quality: A human-evaluated score (1-5) assessing the coherence and logical validity of the generated reasoning steps 98 | - Belief consistency: The degree to which the system maintains consistent beliefs across multiple interactions 99 | 100 | ### 6.3 Results 101 | 102 | Our preliminary results indicate that the Memory Driven Reasoning system achieves performance comparable to chain-of-thought prompting on single-interaction tasks, while demonstrating superior performance on tasks requiring the maintenance of consistent beliefs across multiple interactions. 103 | 104 | | Method | Accuracy | Reasoning Quality | Belief Consistency | 105 | |---------------------------|----------|-------------------|---------------------| 106 | | Baseline LLM | 65% | 2.8 | N/A | 107 | | Chain-of-Thought Prompting| 78% | 3.9 | N/A | 108 | | Memory Driven Reasoning | 82% | 4.2 | 87% | 109 | 110 | Table 1: Comparative results of different approaches on a set of reasoning tasks. 111 | 112 | As shown in Table 1, our Memory Driven Reasoning system outperforms both the baseline LLM and the Chain-of-Thought Prompting approach in terms of accuracy and reasoning quality. Additionally, it demonstrates a high level of belief consistency across multiple interactions, a metric not applicable to the other methods. 113 | 114 | ## 7. Discussion 115 | 116 | Our Memory Driven Reasoning system addresses several key limitations of current AI memory systems: 117 | 118 | - Dynamic nature: Memories and beliefs are updated with each interaction, allowing for rapid adaptation to new information. 119 | - Reasoning transparency: The application layer memory provides greater visibility into the agent's decision-making process. 120 | - Data residency: Organizations can maintain control over sensitive data, addressing privacy and compliance concerns. 121 | 122 | Additionally, our system builds upon recent advancements in memory-efficient LLMs[3], incorporating techniques for reducing memory requirements while maintaining performance. 123 | 124 | While our current implementation is heuristic in nature, it provides a foundation for more rigorous development of dynamic memory and belief systems for AI agents. The integration of chain-of-thought-like reasoning processes within our memory framework shows promise for enhancing the overall reasoning capabilities of LLMs. 125 | 126 | Limitations of our current approach include: 127 | 128 | 1. Scalability challenges with very large belief networks 129 | 2. Potential for belief inconsistencies in complex, contradictory scenarios 130 | 3. Dependence on the quality of the underlying LLM for generating coherent reasoning steps 131 | 132 | ## 8. Conclusion and Future Work 133 | 134 | Memory Driven Reasoning represents a significant step towards more human-like AI agents capable of forming beliefs, learning from experiences, and adapting to user-specific contexts. As a heuristic approach, it provides a foundation for further research into dynamic memory systems for AI. 135 | 136 | Future work will focus on: 137 | 138 | - Developing more rigorous, theoretically-grounded approaches to belief formation and updating 139 | - Conducting large-scale empirical studies to validate the effectiveness of our approach across diverse reasoning tasks 140 | - Exploring the integration of Memory Driven Reasoning with other advanced prompting techniques 141 | - Investigating the potential for transfer learning between different reasoning domains using our memory framework 142 | 143 | By combining the strengths of chain-of-thought prompting with a dynamic memory system, we aim to push the boundaries of AI reasoning capabilities and move closer to truly adaptive and context-aware AI agents. 144 | 145 | ## References 146 | 147 | [1] Zhong, W., Guo, L., Gao, Q., Ye, H., & Wang, Y.
