Vercel AI Playground

Vercel AI Playground is a browser-based environment for testing, comparing, and iterating on prompts across multiple large language models. It supports leading providers such as OpenAI GPT, Anthropic Claude, Google Gemini, Llama, Mistral, and others, allowing users to evaluate model behavior side by side in a single interface. Users can run structured conversations, adjust system prompts, and experiment with different parameters to see how each model responds under identical conditions.

The tool provides a chat-style interface where users can create, save, and refine prompts for tasks such as content generation, code assistance, data transformation, summarization, and question answering. It is particularly useful for developers, product teams, and researchers who need to benchmark models, choose the most suitable provider for a given use case, or debug prompt behavior before integrating an LLM into an application.
