Create an AI request for your collection

View as Markdown

You create AI requests to interact with AI models. You can choose any OpenAI-compatible model, whether it’s from OpenAI, Anthropic, Google, or an alternative provider such as HuggingFace. Use your requests to experiment, test, and evaluate different AI models, including fine-tuned, self-hosted, and local ones. Choose the model that best fits your security requirements, budget, and workflow.

  1. Choose an existing workspace or create a new one.
