What it does

AgentA provides a comprehensive platform for managing and evaluating large language models (LLMs) through prompt management, LLM evaluation, and observability tools.

When to use it
  • •When you need to manage and optimize prompts for your LLM-based application
  • •When evaluating the performance of different LLMs for your specific use case
  • •When requiring detailed observability into your LLM's behavior and performance metrics
Ready-to-paste prompt
curl -X POST 'http://localhost:3000/prompt.playground' -H 'Content-Type: application/json' -d '{"prompt": "What is the capital of France?"}'
Heads up: Ensure you have Node.js version 16 or higher installed, as AgentA requires this version for compatibility
