The Cost-Performance King

Doubao 1.5 Pro from ByteDance has taken the AI world by storm. It’s not just “another model”—it’s a model that matches GPT-4o in reasoning but beats it significantly on price and latency. For developers building high-traffic apps, this is the new standard.

Getting API Access

ByteDance provides access through its Volcengine platform.

1. Register: Sign up at volcengine.com.
2. Credits: Doubao often offers massive free token tiers for new developers.
3. Endpoint: Unlike OpenAI, the endpoint is regional, so choose the one closest to your users.

How to Call the API

The Doubao API is mostly compatible with the OpenAI SDK structure, making migration a breeze!

import openapi

client = openapi.Client(api_key="your_key")

response = client.chat.completions.create(
  model="doubao-1-5-pro",
  messages=[{"role": "user", "content": "How do I optimize a search index?"}]
)

print(response.choices[0].message.content)

Why Switch?

• Video Capabilities: Being the engine behind TikTok, Doubao has deeper native video understanding than almost any other frontier model.
• Latency: It is optimized for the massive throughput ByteDance requires, meaning your users see text appear faster.
