Optimization Platform for Large Language Model Apps

Continuously improve large language model apps with observability, evaluation and fine-tuning tools.

A powerful platform to continuously improve your AI-powered apps.

Leverage user feedback to analyze your models.

Unlock powerful insights with end-user feedback. Easily visualize custom metrics, compare data slices and find actionable ways to improve your models in production.

Run experiments to find the best variants.

Evaluate performance, compare variants, and run experiments in production against custom metrics to find the best prompts and hyperparameters for your users.

Compare performance across model providers.

Easily A/B test new foundation models against GPT-3 and make informed decisions by evaluating the cost, latency, and performance tradeoffs.

Personalize your models to each user.

Seamlessly deploy tailored prompts or models to specific user cohorts with the same API endpoint. Add custom logic for shadow deployments and rollouts.

Fine-tune models for higher performance at lower cost.

Automatically log model generations and user feedback to fine-tune models on your proprietary data with cutting-edge fine-tuning techniques.

A customizable SDK for all your LLMOps needs.

A simple workflow to kickstart your data flywheel.
