Best For

Chatbots & Agents

High-volume conversational AI where cost per message matters

Background Processing

Batch jobs, data enrichment, content generation at scale

Dev/Test Environments

Test your OpenAI integration without burning budget

Problems with OpenAI Pricing

Expensive at Scale

$0.50-$15 per 1M tokens adds up fast for high-traffic apps

Vendor Lock-in

Proprietary models make it hard to switch or self-host later

Unpredictable Costs

Usage spikes = surprise bills. Hard to budget for growth.

How GPU AI Solves This

2

Update base_url

Change one line in your OpenAI client initialization:

# Before
from openai import OpenAI
client = OpenAI(api_key="sk-...")

# After
from openai import OpenAI
client = OpenAI(
    api_key="your-gpuai-key",
    base_url="https://gpuai.app/api/v1"
)
3

Use Same Code

All your existing OpenAI code works as-is:

response = client.chat.completions.create(
    model="gpt-3.5-turbo",  # Maps to Mistral-7B
    messages=[
        {"role": "user", "content": "Hello!"}
    ]
)
print(response.choices[0].message.content)
