Automate Prompt Engineering
& Agent Optimization
Take your Opik LLM evaluation workflows to the next level, using eval metrics to automatically iterate and tune system prompts you can freeze and deploy in production.
Unlock cost, performance, and reliability improvements in a fraction of the time you’d spend on manual prompt engineering.



Trusted by the most innovative AI teams
Automate Multi-Trial Optimization at Scale
Automated prompt engineering gives your complex agentic systems the most predictable LLM performance across multiple models, with efficient iteration built into your LLM eval lifecycle.

Generate, Score, & Implement Elite Prompts
The Opik Agent Optimizer SDK comes with everything you need to generate new prompts automatically, score them based on your eval criteria, and trust that the best version makes it to production.

Run Four Prompt Optimization Algorithms in One Package
Few-Shot Bayesian
Optimizer
- Ideal for text-based chat models with template-based, stable examples
- Automatically finds the best set of few-shot example combinations
- Efficient, probabilistic framework chooses which combination to try next
Multi-Agent Interactive Prompt Optimization (MIPRO)
- Designed for complex, multi-agent systems and tool optimization
- LLM-guided algorithm analyzes an entire chain of prompts and few-shot examples
- Lends structure and interpretability with multi-agent collaboration and interactive refinement
MetaPrompt Optimizer
- Simple to use for early-stage ideation and brainstorming
- Iterates to improve an initial system prompt using LLM-driven suggestions
- Generates and scores multiple prompt candidates and returns the best one
Evolutionary Optimizer
- Optimizes for multiple objectives and adds diversity and exploration to your workflow
- Uses genetic algorithms with selection, mutation, and crossover operations
- Stronger ability to “think outside the box” and discover new prompt solutions
Opik is Free & Fully Open Source
LLM observability should be accessible to everyone building the next generation of AI applications and agents. Opik is truly open source with no gotchas, and the hosted version comes with a full-featured free tier.
The Agent Optimizer SDK is fully available under an Opik open-source license, and it’s included in all Comet subscription plans.
Built for Enterprise, Driven by Community

“LLMs are black boxes. We don’t know what is going on inside them. We needed a solution that allowed us to see how our models behaved, and Opik gives us the ability to understand what went wrong, and share that with the team to debug and iterate faster.”
