Air API lets you select supported models within your Project and test them directly in your browser using the Playground.

​
Supported Models

For detailed specifications and usage examples of each model, see the Models page.
  • Chat: Conversational models that generate responses from text prompts. Suitable for tasks such as chatbots, summarization, and code generation. Pricing is based on input and output tokens (/M tokens).
  • Embedding: Models that convert text into vector embeddings for semantic search, classification, and similarity search. Pricing is based on input tokens (/M tokens).
  • TTS: Models that convert text into speech. Pricing is based on the number of input characters (/K chars).
If the model you need is not available, you can request it through our feedback channel.

​
Playground

The Playground is a web-based interface for testing models directly in your browser. It allows you to quickly validate model behavior and experiment with parameters before integrating the API into your application.
Playground is available only for Chat and TTS models. Embedding models do not provide a Playground and can only be used through the API.
The Playground provides two tabs:
  • Playground — Interact with the selected model directly.
  • README — Learn about the selected model’s capabilities and usage.
You can also access Generate API Key and View Code from the buttons in the upper-right corner. The Playground interface and available settings vary depending on the model type.

​
Chat Models

The Chat Playground provides a conversational interface where you can enter prompts and receive responses from the selected model. Chat Playground Eng Use the Chat Settings panel on the right to configure model behavior.

​
TTS Models

The TTS Playground lets you generate speech from text. Enter the text you want to convert, then click Generate to create and play the audio. Tts Playground Eng Use the TTS Settings panel on the right to configure speech generation.
Chat and Embedding models are priced per million tokens (/M tokens), while TTS models are priced per thousand characters (/K chars). Use the currency toggle (₩ / $) to switch between KRW and USD pricing.
