We enable wisdom to awaken through the unity of knowledge and action, ensuring that every drop of professional expertise is transformed into powerful **AI productivity**. ## ✨ Why LoongFlow? --- **An expert-grade Agent framework that thinks and learns. It empowers Agents to think like scientists, helping developers rapidly transform their professional expertise into expert-level Agents.** <p align="center"> <img src="./assets/images/loongflow_fr_v1.jpg" alt="LoongFlow Framework" width="80%"/> </p> - **Intelligent Thinking**: Innovative PES (Planning-Execution-Summary) Paradigm. LoongFlow empowers Agents with structured thinking to tackle long-range complex reasoning challenges. This enables Agents to iterate through high-difficulty tasks with the rigorous mindset of a human scientist. - **Continuous Learning**: Innovative Multi-Structure Fusion Memory. By actively generating model reasoning contexts, LoongFlow allows Agents to continuously synthesize experience during task iterations. This results in a "run-and-improve" mechanism, achieving lightweight learning and evolution without heavy retraining. We believe that the key to designing an expert-level Agent capable of solving complex problems lies in the **Agent’s thinking paradigm**. The thinking paradigm determines the complexity of problems an Agent can handle and sets the ceiling for its effectiveness. LoongFlow is built specifically for complex tasks requiring long-range reasoning, helping developers rapidly build Agents with domain-expert performance. ### Proven Achievements <div align="center"> | **Domain** | **Achievement** | **Example** | | ------------------------------------------------------ |----------------------------------------------------------------------------------------------------------------------------------| ------------------------------------------------------------------------------------------------------ | | **Mathematical Challenges (Tao’s & AlphaEvolve sets)** | Outperformed the best human results on 11 problems and surpassed AlphaEvolve’s results on 7 problems, achieving the latest SOTA. | [Circle Packing](./agents/math_agent/examples/packing_circle_in_unit_square) | | **MLE-bench (Kaggle Challenges)** | Achieved medals across all 48 Kaggle competitions, including 26 Gold Medals. | [Stanford-Covid-Vaccine](./agents/ml_agent/examples/mlebench/competitions/hard/stanford-covid-vaccine) | </div> ### LoongFlow vs Traditional Agent Approaches: <table> <tr> <th align="left">Aspect</th> <th align="left">Prompt / Tool-Based Agents</th> <th align="left">OpenEvolve-Style Evolution</th> <th align="left">LoongFlow</th> </tr> <tr> <td><strong>Core Loop</strong></td> <td>Generate → Retry</td> <td>Mutate → Select</td> <td>Plan → Execute → Summary</td> </tr> <tr> <td><strong>Reasoning Depth</strong></td> <td>Shallow</td> <td>Limited</td> <td>Long-horizon, structured</td> </tr> <tr> <td><strong>Learning from Failure</strong></td> <td>❌</td> <td>Partial</td> <td>✅ Explicit reflection</td> </tr> <tr> <td><strong>Experience Reuse</strong></td> <td>❌</td> <td>❌</td> <td>✅ Structured memory</td> </tr> <tr> <td><strong>Stability</strong></td> <td>Fragile</td> <td>Often unstable</td> <td>Stable convergence</td> </tr> <tr> <td><strong>Best Use Case</strong></td> <td>Simple automation</td> <td>Search-heavy tasks</td> <td>Expert-level problem solving</td> </tr> </table> ## Quick Start --- ### Installation > LoongFlow requires **Python 3.12** or higher. ```bash # Install uv/conda and clone repository uv: https://docs.astral.sh/uv/getting-started/installation/ Miniforge: https://conda-forge.org/download/ # Install with uv cd LoongFlow uv venv .venv --python 3.12 source .venv/bin/activate uv pip install -e . # Install with conda cd LoongFlow conda create -n loongflow python=3.12 conda activate loongflow pip install -e . ``` ### Run Examples #### Run General Agent ```bash # Config LLM: Edit task_config.yaml or set environment variables # Supports Anthropic-compatible models export ANTHROPIC_API_KEY="your-api-key" export ANTHROPIC_BASE_URL="your-endpoint" # Run beginner example -

To achieve this, LoongFlow organizes agent behavior into a thinking–learning–evolving loop. --- ### From Evolutionary Agents to Thinking Agents From Evolutionary Agents to Thinking Agents Frameworks such as **OpenEvolve** and **AlphaEvolve** demonstrated that agents can improve through iteration, evaluation, and selection. This marked a clear step beyond static prompting. However, in real-world expert tasks, purely evolutionary loops often struggle because: - Exploration is blind or weakly guided - Long-horizon reasoning breaks easily - Experience remains task-specific - Agents converge prematurely to local optima The core issue is not evolution itself, but **the lack of a structured thinking process**. LoongFlow addresses this by shifting the abstraction: from _evolving outputs_ to **standardizing how agents think, act, and learn**. --- ### PES Thinking Paradigm At the core of LoongFlow is the **PES (Plan–Execute–Summary) thinking paradigm**, inspired by how human experts conduct research: Each agent iteration follows the same explicit structure: <table> <tr> <td width="33%"> Plan - Understand the task and constraints - Retrieve relevant past experience - Design a clear, high-quality execution blueprint > Planning ensures generation is deliberate rather than blind. </td> <td width="33%"> Execute - Perform structured experimentation - Verify intermediate results - Avoid low-value or redundant trials > Execution becomes controlled experimentation, not guesswork. </td> <td width="33%"> Summary - Reflect deeply on successes and failures - Extract reusable insights - Persist experience into structured memory > Summary prevents agents from repeating the same mistakes. </td> </tr> </table> <p align="center"> <img src="./assets/images/pes-flow.jpg" alt="LoongFlow Framework" width="80%"/> </p> PES transforms evolution from a mutation-driven process into a **reasoning-guided improvement loop**. --- ### Learning & Evolutionary Memory Thinking alone is not enough. To improve over time, agents must **remember, generalize, and escape local optima**. LoongFlow integrates PES with a hybrid evolutionary memory system: - Multi-Island + MAP-Elites to preserve diversity - Adaptive Boltzmann selection to balance exploration and exploitation - Global evolutionary tree memory for long-range experience retrieval This allows agents to perform **jump-style reasoning** — leveraging past discoveries to move beyond incremental local search. ## LoongFlow
