Qu'est-ce que Promptmetheus ?

Promptmetheus is a prompt engineering IDE for composing structured prompts, testing reliability across models and datasets, optimizing performance for prompt chains, and collaborating on shared prompt libraries for LLM-powered apps, agents, and workflows.

Fonctionnalités principales

  • Prompt Composition

    Compose structured prompts from modular sections (e.g. Context, Task, Instructions, Samples, Primer) and rapidly iterate through different variations for better composability and fine-tuning.

  • Prompt Variables

    Define variables at project or prompt level to keep recurring details flexible and consistent.

  • Prompt Evaluators

    Set up custom evaluators and automatically validate each completion against specified constraints.

  • Model Catalog

    Test prompts with 150+ cutting-edge LLMs across 15 APIs, fine-tune model parameters, or configure custom models.

  • Projects

    Organize prompts, datasets, and completions into projects and track relevant statistics on the dashboard.

  • Test Datasets

    Use datasets to test with dynamic context and simulate user data or retrieved content for rapid iteration.

  • Completion Ratings

    Rate completion quality and visualize results broken down by model and used variants.

  • Cost Calculation

    Estimate inference costs for completions based on different models, inputs, and configurations.

  • Full Traceability

    Trace every change in the prompt-design workflow with detailed versioning and changelogs.

  • Stats and Insights

    Surface hidden patterns and correlations to increase efficiency during the prompt design process.

  • Real-time Sync

    Sync changes to the prompt library in real-time with other devices and team members.

  • Data Export

    Export prompts and completions in .txt, .csv, .xlsx, or .json format.

Cas d'utilisation

  • #1

    LLM-Powered Applications

    Compose, test, and optimize prompts for building and improving LLM-powered applications.

  • #2

    Agents and Prompt Chains

    Optimize each prompt in a sequence so end-to-end performance and reliability of prompt chains and agents are not compromised by compounding errors.

  • #3

    Workflows and Automations

    Develop prompts for LLM-augmented services, workflows, and automations with structured composition and evaluation tools.

  • #4

    Team Prompt Engineering

    Collaborate in real-time on shared workspaces and build a shared prompt library for teams.
