## Code Example:
\`\`\`python
import opik

client = opik.Client(api_key="YOUR_API_KEY")
# Create a new prompt
prompt = client.create_prompt(name="My Customer Support Prompt")
# Store the prompt ID for future use

## Description:

## Use Cases:

- Ensuring responses are grounded in provided context
- Identifying fabricated information
- Quality control for knowledge-intensive applications
## Parameters:
- answer: The LLM-generated text to evaluate
- context: Optional reference text to check against (if provided)
## Example:
\`\`\`javascript

Opik provides a variety of metrics to evaluate LLM outputs:

- Hallucination: Detects unsupported or factually incorrect information
- AnswerRelevance: Evaluates how relevant an answer is to a given question
- ContextPrecision: Measures how precisely an answer uses the provided context
- ContextRecall: Assesses how completely an answer captures relevant information
- Moderation: Detects harmful or inappropriate content
## Rule-based Metrics:
- Equals: Simple exact match comparison
- RegexMatch: Validates answers against regular expression patterns
- Contains: Checks if the answer contains specific substrings
- LevenshteinRatio: Measures string similarity using Levenshtein distance`,

## Description:
Spans are individual units within a trace that represent discrete operations or steps in your LLM application. They help break down complex interactions into manageable pieces for analysis.
## Key Features:
- Hierarchical relationship (parent-child)
- Timing information for performance analysis
- Custom attributes for context
- Support for nested operations
- Automatic correlation with parent traces
## Use Cases:
- Performance bottleneck identification
- Detailed step-by-step analysis
- Tracking complex multi-step LLM workflows
- Measuring time spent in different components
- Correlating errors with specific operations`,

- traces: Complete records of LLM interactions
- spans: Individual units within a trace
- feedback: Annotations for traces with evaluations
- search: Finding specific traces based on content or metadata
- visualization: Tools to understand traces and spans`,
