# Overview

> OpenGround is OpenLIT's AI model comparison tool - an LLM playground for running one prompt across many providers at once and comparing cost, speed, and quality

OpenGround is OpenLIT's **AI model comparison tool** - an LLM playground built for a specific job: run **one prompt across many providers and models at once**, then compare the results side-by-side. Pick a prompt, pick the providers you want to test, click **Evaluate providers**, and see cost, speed, and quality laid out next to each other. Every run is saved automatically to a searchable history, so you can build up a record of what you've tested and reopen or reload any past run later.

## What you get

## Model and provider management

Model and provider management itself - adding providers and editing pricing - lives on **Monitor → Costs → Manage models**. OpenGround and Manage models share the same underlying providers and models, so anything you configure in one is immediately available in the other.

## Frequently asked questions

<AccordionGroup>
  <Accordion title="What is OpenGround used for?">
    OpenGround runs the same prompt across multiple LLM providers and models at once, so you can compare cost, speed, and response quality side-by-side before choosing a model for production.
  </Accordion>

  <Accordion title="How many providers are supported out of the box?">
    14: OpenAI, Anthropic, Google, Mistral, Groq, Perplexity, Azure, Cohere, Together AI, Fireworks, DeepSeek, xAI, Hugging Face, and Replicate. See [Run a Comparison](/latest/openlit/prompts-experiments/openground/run-a-comparison) for how to configure one.
  </Accordion>

  <Accordion title="Can I test a model that isn't built in?">
    Yes. When configuring a provider in OpenGround, switch to "Use Custom Model" and type any model ID directly, with its own input/output pricing. There's no field for a custom endpoint or base URL - only the model ID and its pricing are configurable.
  </Accordion>

  <Accordion title="Are comparison runs saved automatically?">
    Yes. Every run is saved to a searchable history with cost, speed, and token-efficiency summaries - there's no separate save step. See [Results & History](/latest/openlit/prompts-experiments/openground/results-and-history) for how to find and reopen past runs.
