## Interactive Prompt Engineering with Opik's Playground

This video demonstrates how to use Opik's [prompting playground](https://www.comet.com/docs/opik/prompt_engineering/playground) for hands-on [prompt engineering](https://www.comet.com/docs/opik/prompt_engineering/prompt_management) and testing. The [playground](https://www.comet.com/docs/opik/prompt_engineering/playground) provides an interactive environment where you can craft [prompts](https://www.comet.com/docs/opik/prompt_engineering/prompt_management), test variations, and run [experiments](https://www.comet.com/docs/opik/evaluation/evaluate_your_llm) directly within the UI. You'll learn how to leverage versioned [prompts](https://www.comet.com/docs/opik/prompt_engineering/prompt_management) from your library, conduct A/B testing, and seamlessly transition from prompt development to full [dataset evaluation](https://www.comet.com/docs/opik/evaluation/manage_datasets).

## Key Highlights

* **Parallel A/B Testing**: Run multiple [prompt](https://www.comet.com/docs/opik/prompt_engineering/prompt_management) variations side-by-side to compare outputs and identify the most effective approaches for your use case
* **Flexible [Prompt](https://www.comet.com/docs/opik/prompt_engineering/prompt_management) Types**: Switch between system and user [prompts](https://www.comet.com/docs/opik/prompt_engineering/prompt_management) depending on your workflow needs, from simple queries to complex system instructions
* **Versioned [Prompt](https://www.comet.com/docs/opik/prompt_engineering/prompt_management) Integration**: Load [prompts](https://www.comet.com/docs/opik/prompt_engineering/prompt_management) directly from your managed [prompt library](https://www.comet.com/docs/opik/prompt_engineering/prompt_management), always accessing the latest committed version for consistent testing
* **[Dataset](https://www.comet.com/docs/opik/evaluation/manage_datasets)-Driven [Experiments](https://www.comet.com/docs/opik/evaluation/evaluate_your_llm)**: Integrate test [datasets](https://www.comet.com/docs/opik/evaluation/manage_datasets) directly into [playground](https://www.comet.com/docs/opik/prompt_engineering/playground) sessions to run comprehensive [evaluations](https://www.comet.com/docs/opik/evaluation/overview) right from the interface
* **Configurable Model Parameters**: Adjust creativity levels, output token limits, and other model settings to fine-tune behavior for your specific requirements
* **Template Variable Support**: Use mustache/handlebar notation (e.g., `{{question}}`) to create dynamic [prompts](https://www.comet.com/docs/opik/prompt_engineering/prompt_management) that work with [dataset](https://www.comet.com/docs/opik/evaluation/manage_datasets) variables
* **Live Version Control**: Save [prompt](https://www.comet.com/docs/opik/prompt_engineering/prompt_management) modifications directly from the [playground](https://www.comet.com/docs/opik/prompt_engineering/playground) with commit messages and metadata, creating new versions in your [prompt library](https://www.comet.com/docs/opik/prompt_engineering/prompt_management)
* **Instant [Experiment](https://www.comet.com/docs/opik/evaluation/evaluate_your_llm) Creation**: Generate [experiments](https://www.comet.com/docs/opik/evaluation/evaluate_your_llm) with visual feedback banners, then view comprehensive results including outputs from your Q\&A [datasets](https://www.comet.com/docs/opik/evaluation/manage_datasets)
* **Seamless Workflow Integration**: Bridge the gap between [prompt](https://www.comet.com/docs/opik/prompt_engineering/prompt_management) development, testing, and full [evaluation](https://www.comet.com/docs/opik/evaluation/overview) without leaving the Opik environment
