Prompts like
a Pro
Promptmetheus breaks prompts down into LEGO-like blocks for better composability, e.g. Context ⇢ Task ⇢ Instructions ⇢ Samples (shots) ⇢ Primer. You can play with different variations for each section and systematically fine-tune your prompts for minimal cost and maximum performance.

Reliability
The Prompt IDE includes a range of tools to evaluate your prompts under various conditions. For instance, Datasets enable rapid iteration with different inputs, while completion Ratings and the respective visual statistics help gauge output quality.

Prompt
Performance
End-to-end performance and reliability of prompt chains (agents) depend heavily on the accuracy of each prompt in the sequence. Errors can compound and compromise the final output. Promptmetheus can help you optimize each prompt in the chain to consistently generate great completions.
Traceability
Track the complete history of the prompt design process.
Cost Estimation
Calculate inference costs under different configurations.
Data Export
Export prompts and completions in different file formats.
Analytics
View prompt performance statistics, charts, and insights.
Prompt Chaining
Chain prompts together for advanced tasks and workflows.
Prompt Endpoints
Deploy prompts to dedicated AIPI endpoints.
Data Loaders
Inject external data sources directly into prompts.
Vector Embeddings
Add more context to prompts via vector search.
