Accessing APIs Directly

GPT-4o requests example

Python request example for chat with Open AI API:

from openai import OpenAI
client = OpenAI()

completion = client.chat.completions.create(
  model="gpt-4o",
  messages=[
    {"role": "developer", "content": "You are a helpful assistant."},
    {"role": "user", "content": "Hello!"}
  ]
)

print(completion.choices[0].message)

{
  "messages": [
    {
      "role": "system",
      "content": "You're an assistant"
    },
    {
      "role": "user",
      "content": "Hi"
    }
  ],
  "model": "grok-2-vision-1212"
}

Grok-2 offers slightly lower input costs for text ($2.00 vs. $2.50 per 1M tokens) but lacks caching and fine-tuning options, while both models charge $10 per 1M output tokens. GPT-4o provides additional value with audio processing ($40 input, $80 output per 1M tokens) and fine-tuning capabilities, which Grok-2 does not support. For pure text-based tasks, Grok-2 is marginally cheaper, but GPT-4o is more versatile, making it the better choice for businesses needing customization, caching, or multimodal applications.
