# 🚀 Nen: Minimalist LLM Framework in Zig
[](https://ziglang.org/)
[](LICENSE)
[](https://github.com/Nen-Co/nen)
**Nen** is a minimalist LLM framework built in Zig following the Nen way: statically typed, zero-allocation, and using the Nen ecosystem for maximum performance: designed for production-scale AI workflows.
## 🌟 Why Nen?
### **Minimalist Design**
- **Just ~300 lines** for the core framework (vs LangChain's 405K lines)
- **Zero bloat, zero dependencies, zero vendor lock-in**
- **Everything you love**: Agents, Workflows, RAG, and more
### **Nen Way Performance**
- **Statically typed**: Compile-time safety and optimization
- **Zero-allocation**: Static memory pools for predictable performance
- **Nen ecosystem**: Seamless integration with NenCache, NenDB, nen-io, nen-json
- **Sub-microsecond latency**: High-performance node execution
### **Production Ready**
- **High throughput**: 1000+ flows per second
- **Built-in caching**: NenCache integration for performance
- **Monitoring**: Comprehensive metrics and observability
- **Scalability**: Handle millions of AI workflows

// Create a simple agent flow
var flow = try nen.createAgentFlow(allocator, "Assistant",
"You are a helpful AI assistant.");
defer flow.deinit();
// Execute the flow
try flow.execute();
// Get execution statistics
const stats = flow.getStats();
std.debug.print("Success rate: {d:.1}%\n", .{stats.getSuccessRate() * 100.0});
}
