and all popular inference APIs
and all popular inference APIs
Compose
Prompts
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 block and systematically fine-tune your prompts for optimal performance.
Test
Prompts
The Prompt IDE includes a range of tools to evaluate your prompts under various conditions. For instance, Datasets enable rapid iteration across different inputs, while completion Ratings and the respective visual indicators help gauge output quality.
Optimize
Prompts
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.
Roadmap
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.
Models
We support all the latest LLMs and inference APIs.
