    model="kugel-1",
    cfg_scale=2.5,  # Higher CFG for more expressive output
)

const audio = await client.tts.generate({

Generation Parameters

​

CFG Scale Guide

• 1.0-1.5: More natural, relaxed delivery
• 2.0: Balanced (default)
• 2.5-3.0: More expressive, dynamic
• 3.5-5.0: Maximum expressiveness, best for dramatic content

​

Listing Models

models = client.models.list()

for model in models:
    print(f"{model.id}: {model.name}")
    print(f"  Description: {model.description}")
    print(f"  Parameters: {model.parameters}")
    print(f"  Max Input: {model.max_input_length} characters")

const models = await client.models.list();

for (const model of models) {
  console.log(`${model.id}: ${model.name}`);
  console.log(`  Description: ${model.description}`);
  console.log(`  Parameters: ${model.parameters}`);
  console.log(`  Max Input: ${model.maxInputLength} characters`);
}
