FOR DEVELOPERS AT THE FRONTIER
1. INTELLIGENT MODEL ROUTING
Intelligent model routing automatically predicts which model to use for each input, dramatically reducing costs over long-running agent workloads while maintaining or improving accuracy.
2. PROMPT OPTIMIZATION
Prompt optimization automatically optimizes your prompt templates across every model in your stack, outperforming days of manual prompt engineering in minutes of background processing.
3. AGENT OPTIMIZATION
Our tools improve model accuracy and cost efficiency for multi-step workflows and autonomous agents, dramatically improving success rates and unit economics over long-running agent trajectories.
We use Not Diamond to power our intelligent routing feature, giving developers the ability to automatically use the best model on every input across every leading language model.
