GPT 5.2 Pricing Breakdown

One of the most important considerations when choosing an API is understanding the cost structure. The GPT 5.2 API pricing through SkillBoss is straightforward and competitive:

• Input Tokens: $1.75 per 1 million tokens
• Output Tokens: $14.00 per 1 million tokens

Understanding Token-Based Pricing

Tokens are the fundamental units that language models use to process text. Roughly speaking, one token represents about 4 characters or 0.75 words in English. This means:

• 1,000 tokens ≈ 750 words
• A typical conversation exchange (user message + AI response) might use 500-2,000 tokens
• Input tokens are counted from your prompts and context
• Output tokens are counted from the model's generated responses

Cost Examples

Let's break down some real-world scenarios:

Scenario 1: Customer Support Chatbot

• Average interaction: 200 input tokens, 300 output tokens
• Cost per interaction: (200 × $1.75 / 1M) + (300 × $14.00 / 1M) = $0.0042
• 10,000 interactions/month: approximately $42

Scenario 2: Document Analysis

• Average analysis: 2,000 input tokens, 500 output tokens
• Cost per analysis: (2,000 × $1.75 / 1M) + (500 × $14.00 / 1M) = $0.0105
• 1,000 documents/month: approximately $10.50
