How to Use Doubao 1.5 Pro API

The Doubao 1.5 Pro API supports communication requests via both HTTP and HTTPS protocols, with HTTPS recommended for enhanced security.

Getting Started

To begin using Doubao 1.5 Pro API:

  1. Create a new API key from Volcengine
  2. Set <YOUR_API_KEY> as an environment variable
  3. Configure Your Desired Model
  4. Set Up Environment and Make the Call

Example Implementation in Python

import os
from volcenginesdkarkruntime import Ark
# Read Your Volcengine API Key from the Environment Variable
client = Ark(api_key=os.environ.get("ARK_API_KEY"))
completion = client.chat.completions.create(
    # Replace <YOUR_ENDPOINT_ID> with Your Volcengine Endpoints ID
    model="<YOUR_ENDPOINT_ID>",
    messages=[
        {"role": "user", "content": "Hello"}
    ]
)
print(completion.choices[0].message)

Using cURL

curl https://ark.cn-beijing.volces.com/api/v3/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer $ARK_API_KEY" \
  -d '{
    "model": "<YOUR_ENDPOINT_ID>",
    "messages": [
        {
            "role": "user",
            "content": "Gello"
        }
    ]
  }'

Advanced Features

Visual Multimodal Capabilities

In terms of vision, Doubao-1.5 Pro has made comprehensive technical advancements compared to its previous version.

Speech Multimodal Capabilities

Unlike traditional ASR + LLM + TTS cascaded approaches, Doubao-1.5 Pro not only boasts high comprehension (high IQ) but also excels in speech expressiveness and control. The model demonstrates exceptional emotional continuity both in its responses and speech output. By integrating speech and text tokens, Doubao-1.5 Pro provides the necessary foundation for scaling speech multimodal data effectively.
