LLM Auto Optimizer

Automatically optimize your LLM infrastructure with intelligent, real-time feedback loops

Features • Quick Start • Architecture • Documentation • Contributing

Overview

The LLM Auto Optimizer is a production-ready, continuous feedback-loop agent that automatically adjusts model selection, prompt templates, and configuration parameters based on real-time performance, drift, latency, and cost data. Built entirely in Rust for maximum performance and reliability.

Why LLM Auto Optimizer?

💰 Reduce LLM costs by 30-60% through intelligent model selection and prompt optimization
⚡ Sub-5-minute optimization cycles for rapid adaptation to changing conditions
🎯 Multi-objective optimization balancing quality, cost, and latency
🛡️ Production-grade reliability with 99.9% availability target
🚀 Progressive canary deployments with automatic rollback on degradation
🔒 Enterprise-ready with comprehensive audit logging and compliance
🌐 Complete API coverage with REST & gRPC endpoints
🖥️ Beautiful CLI tool with 40+ commands for operations

Optimization Strategies

1. A/B Prompt Testing

Test multiple prompt variations with statistical significance testing (p < 0.05) to identify the most effective prompts.

// Example: Test two prompt variations
let experiment = ExperimentBuilder::new()
    .name("greeting_test")
    .variant("control", "Hello, how can I help?")
    .variant("treatment", "Hi there! What can I assist you with today?")
    .metric("user_satisfaction")
    .significance_level(0.05)
    .build();

2. Reinforcement Feedback

Learn from user feedback using contextual bandits and Thompson Sampling to continuously improve model selection.

3. Cost-Performance Scoring

Multi-objective Pareto optimization balancing quality, cost, and latency to find the optimal configuration.

4. Adaptive Parameter Tuning

Dynamically adjust temperature, top-p, max tokens based on task characteristics and historical performance.

5. Threshold-Based Heuristics

Detect performance degradation, drift, and anomalies with automatic response and alerting.
