Replacing your OpenAI integration with ZC Inference Exchange can reduce your costs by up to 70% without changing your application code. This guide demonstrates how to switch to ZC Inference Exchange by updating a single URL, maintaining the same behavior while significantly lowering your bill. ZC Inference Exchange offers an OpenAI-compatible API, making the transition seamless for engineers who have built applications using the /v1/chat/completions endpoint.

Before: OpenAI Integration

To illustrate the transition, let's start with a typical OpenAI integration. Your application might use the following code snippet to interact with OpenAI's API:

import requests

openai_url = 'https://api.openai.com/v1/chat/completions'
headers = {
    'Authorization': 'Bearer YOUR_OPENAI_API_KEY',
    'Content-Type': 'application/json'
}
data = {
    'model': 'gpt-3.5-turbo',
    'messages': [{'role': 'user', 'content': 'Hello, how are you?'}]
}
response = requests.post(openai_url, headers=headers, json=data)
print(response.json())

After: ZC Inference Exchange Integration

To switch to ZC Inference Exchange, you only need to change the URL and API key. The rest of your code remains the same. Here is the updated code:

import requests

zcx_url = 'https://zcx.zctechnologies.org/v1/chat/completions'
headers = {
    'Authorization': 'Bearer YOUR_ZCX_API_KEY',
    'Content-Type': 'application/json'
}
data = {
    'model': 'qwen2.5:32b',
    'messages': [{'role': 'user', 'content': 'Hello, how are you?'}]
}
response = requests.post(zcx_url, headers=headers, json=data)
print(response.json())

Cost Comparison

The cost savings are significant. For instance, the Starter plan at ZC Inference Exchange offers 1.5M tokens for $99 per month, which is $66 per 1M tokens. In contrast, OpenAI's pricing for similar usage is approximately $200 per 1M tokens, representing a 67% cost reduction. Our Pro and Business plans offer even better rates, making ZC Inference Exchange the most cost-effective solution for large-scale applications.

Conclusion

Switching to ZC Inference Exchange is straightforward and can lead to substantial cost savings.
