We built LoongFlow after struggling with prompt-heavy agent systems that
didn't improve across runs.
Instead of tuning prompts, we structure agent behavior as an iterative
plan–execute–summarize loop, where failures are explicitly summarized
and reused in later planning.
The repo includes runnable examples and evolution logs.
Happy to answer implementation or design questions.
We’re building LoongFlow, a cutting-edge open-source evolutionary agent framework that integrates large language model reasoning into evolutionary search. If you’re passionate about autonomous agents, AI optimization, or open-source collaboration, we'd love your help in developing new agents, improving algorithms, and expanding benchmarks. Check out the repo here: GitHub Link.
Looking for contributors in:
Algorithm development
Benchmarking
Documentation & tutorials
Memory systems & LLM integration

Each task is unique, unless we provide share memory for them. It means when you start a task, it will run the full evolutionary process from the start.
Hi HN, we are the team behind LoongFlow.
We built this framework to use evolve thinking solve any tasks.
LoongFlow brings Evolutionary Algorithms (EA) into the agent workflow. It evolves taskss over generations (via selection, crossover, and mutation) to maximize performance.
Key features:
General-Evolve: Good at Algorithm task.
ML-Evolve: Specialized for machine learning tasks.
We built this framework to solve the problem of Agent brittleness—where standard ReAct agents often get stuck or fail when prompts aren't perfectly hand-tuned.
Instead of manual prompt engineering, LoongFlow brings Evolutionary Algorithms (EA) into the agent workflow. It treats prompts and logic as "populations" that evolve over generations (via selection, crossover, and mutation) to maximize performance.
Key features:
General-Evolve: Auto-optimizes prompts and code logic.
ML-Evolve: Specialized for machine learning tasks (AutoML agent).
What’s different: Agents autonomously design and evolve ML models (not manual tuning, not classic AutoML)
Status: Running in production
