About this playground

The chat playground sends your messages to the selected model through the same /v1/chat/completions endpoint your code will use, with the system prompt and sampling parameters from the panel. Every model here is open-weight and billed per token from your prepaid balance; the reply shows elapsed time and token usage so you can estimate cost before you integrate.

Tips

  • Reasoning models (GPT-OSS, DeepSeek, GLM) think before answering — keep max_tokens at a few hundred or more.
  • Use View code to copy a cURL request with exactly the parameters you set; swap in the Python or Node SDK from the model page.
  • Compare speed and price on the comparison pages before choosing a default.
