FOR DEVELOPERS AT THE FRONTIER
1. AGENT OPTIMIZATION
Agent optimization leverages self-improving algorithms to optimize multi-step workflows and autonomous agents, dramatically improving success rates over long-running agent trajectories.
2. PROMPT OPTIMIZATION
Prompt optimization automatically optimizes your static prompt templates across any model and any provider, outperforming days of manual prompt engineering in minutes of background processing.
3. INTELLIGENT ROUTING
Intelligent routing is an ultra low-latency runtime optimization that predicts which model to use for each input, maximizing accuracy while offering dynamic cost and latency tradeoffs.
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.
