GPT 4O Mini Pricing: Cost-Effective AI via SkillBoss

One of the most compelling aspects of GPT-4O Mini is its exceptional pricing structure. When accessed through SkillBoss, you get transparent, straightforward pricing without needing to manage multiple vendor accounts.

Pricing Breakdown

• Input tokens: $0.15 per 1 million tokens
• Output tokens: $0.60 per 1 million tokens

To put this in perspective, processing 100,000 input tokens (roughly 75,000 words) costs just $0.015, while generating 100,000 output tokens costs $0.06. For most applications, this translates to fractions of a cent per API call.

Cost Comparison Example

Let's examine a practical scenario: building a customer support chatbot that handles 10,000 conversations daily, with an average of 500 input tokens and 300 output tokens per conversation.

Daily costs:

• Input: 5,000,000 tokens × $0.15 / 1M = $0.75
• Output: 3,000,000 tokens × $0.60 / 1M = $1.80
• Total daily cost: $2.55
• Monthly cost: ~$76.50

This pricing makes GPT-4O Mini accessible for businesses of all sizes, from indie developers to enterprise operations.

Why Use SkillBoss for GPT 4O Mini API?

SkillBoss provides OpenAI-compatible API access, meaning you can use familiar OpenAI SDK patterns without creating separate vendor accounts. You get unified billing, consistent API formatting, and access to multiple model providers through a single integration point.

Code Examples: Implementing GPT 4O Mini API

Python Example

Here's how to use GPT-4O Mini API with Python using the OpenAI SDK:

from openai import OpenAI

# Initialize SkillBoss client
client = OpenAI(
    api_key="your_skillboss_api_key",
    base_url="https://api.heybossai.com/v1"
)

# Create a chat completion
response = client.chat.completions.create(
    model="openai/gpt-4o-mini",
    messages=[
        {"role": "system", "content": "You are a helpful assistant specialized in technical documentation."},
        {"role": "user", "content": "Explain what API rate limiting is and why it matters."}
    ],
    temperature=0.7,
    max_tokens=500
)

# Extract the response
answer = response.choices[0].message.content
print(answer)

# Check token usage
print(f"Input tokens: {response.usage.prompt_tokens}")
print(f"Output tokens: {response.usage.completion_tokens}")

cURL Example

For direct HTTP requests or testing, here's the cURL approach:

curl https://api.heybossai.com/v1/chat/completions \
  -H "Content-Type: application/json" \
  -H "Authorization: Bearer your_skillboss_api_key" \
  -d '{
    "model": "openai/gpt-4o-mini",
    "messages": [
      {
        "role": "system",
        "content": "You are a helpful coding assistant."
      },
      {
        "role": "user",
        "content": "Write a Python function to validate email addresses."
      }
    ],
    "temperature": 0.7,
    "max_tokens": 300
  }'

Streaming Example

For real-time applications like chatbots, use streaming responses:

from openai import OpenAI

client = OpenAI(
    api_key="your_skillboss_api_key",
    base_url="https://api.heybossai.com/v1"
)

stream = client.chat.completions.create(
    model="openai/gpt-4o-mini",
    messages=[
        {"role": "user", "content": "Write a short story about a robot learning to cook."}
    ],
    stream=True
)

for chunk in stream:
    if chunk.choices[0].delta.content:
        print(chunk.choices[0].delta.content, end="")
