Simple Steps to Evaluate Your Prompts
Evaluating your AI prompts is crucial for building high-performing and reliable models. A well crafted prompt is key to best output. Follow this simple steps to get started

Create your Project and Select a dataset
Start by creating your project, choosing the right dataset. A well-curated dataset ensures your prompts are evaluated against high-quality & relevant data, setting the foundation for best results.

Create or update your prompt
Design your prompt carefully to achieve the desired model behavior. Test different variations and refine your wording to optimize clarity, specificity, and effectiveness.

Select AI models to compare

Define evaluation parameters and involve SMEs
Set clear evaluation parameters such as accuracy, response time, and relevance. Involve Subject Matter Experts (SMEs) to provide qualitative feedback & ensure the model meets business expectations.
Run evaluations and analyze results with interactive dashboards.

Frequently Asked Questions
- Identify datasets, models, and presets: Users select the datasets, models, and any existing presets for the evaluation. Custom grading parameters specific to the workload are configured.
- Understand presets: A preset is a model configuration that includes parameters like max_tokens, temperature, top_p, and top_k. These settings control the behavior and output quality of the model. Each model can have up to three presets, offering flexibility to test different configurations.
- Kick off the evaluation: Once everything is set, the user starts the evaluation process.
- Generate and store LLM responses: The system generates LLM responses based on the provided prompts and datasets, and the results are securely stored.
- User and expert grading: Users can review and grade the responses. Subject matter experts (SMEs) can also be invited to provide their evaluations.
- Full evaluation with LLM as a judge: Once human grading is complete, users can trigger a full evaluation where the LLM acts as a judge, using the human feedback to evaluate other records and ensure consistency.
