It operates in a single stream of thought, autonomously reasoning about the task, dynamically discovering necessary tools, and executing actions. This allows the LRM to maintain a global perspective and unlock its full autonomous potential. +--- -- **Autonomous Memory Folding & Brain-Inspired Memory**: When facing complex problems, DeepAgent can autonomously trigger memory folding. This process consolidates the interaction history into a structured memory, allowing the agent to restart its reasoning with a condensed yet comprehensive understanding of its progress. The memory architecture is brain-inspired and consists of: - - **Episodic Memory**: A high-level log of key events, decisions, and sub-task completions. - - **Working Memory**: Contains the most recent information, including the current sub-goal and near-term plans. - - **Tool Memory**: Consolidates tool-related interactions, allowing the agent to learn from experience and refine its strategies. +## Installation -- **End-to-End RL Training with ToolPO**: To effectively train the agent, we introduce ToolPO, a policy optimization method featuring: - - An **LLM-based Tool Simulator** that mimics real-world APIs, ensuring stable and efficient training. - - **Tool-Call Advantage Attribution**, which assigns fine-grained credit to correct tool invocation tokens, providing a more precise learning signal. +### Requirements +- Python 3.8+ +- pydantic +- torch (optional, for emotion classification) +- numpy (optional, for advanced features) -## 🔧 Installation +### Standard Installation -### Environment Setup ```bash -# Create conda environment -conda create -n deepagent python=3.10 -conda activate deepagent +git clone https://github.com/Tuesdaythe13th/AccessibleDeepAgent.git +cd AccessibleDeepAgent -# Install requirements -cd DeepAgent-main +# Create virtual environment +python3 -m venv .venv +source .venv/bin/activate # Windows: .venv\Scripts\activate + +# Install dependencies pip install -r requirements.txt ``` - +### Minimal Installation (No ML) -

🤖 Model Serving

 -Before running DeepAgent, ensure your reasoning model and auxiliary model are served using vLLM. DeepAgent is designed to work with powerful reasoning models as the main agent and can use an auxiliary model for tasks like memory generation and tool selection. For more details, please refer to [vLLM](https://github.com/vllm-project/vllm). +--- -For the main reasoning model, we recommend using the following models. Performance improves from top to bottom, but computational cost also increases accordingly.
