📊 OpenAI API Pricing (2024)
How OpenAI Pricing Works
OpenAI charges based on tokens, which are pieces of words. English text averages about 1.3 tokens per word. Your cost depends on both the tokens you send (input/prompt) and the tokens the model generates (output/completion).
Total Cost = (Input Tokens × Input Rate) + (Output Tokens × Output Rate)
❓ Frequently Asked Questions
Which OpenAI model should I use?
For most use cases, GPT-4o-mini offers the best balance of cost and capability. Use GPT-4o for complex reasoning tasks. Reserve o1 models for advanced problem-solving in math, science, or coding.
How do I reduce OpenAI costs?
Use GPT-4o-mini instead of GPT-4o for simple tasks. Write concise prompts. Set max_tokens limits. Cache API responses. Use batch processing. Consider fine-tuning for repetitive tasks.
Does OpenAI offer volume discounts?
Yes, OpenAI offers committed use discounts for high-volume users. Contact their sales team for enterprise pricing. They also offer prompt caching discounts for repeated prompts.
What's the difference between GPT-4o and o1?
GPT-4o is optimized for fast, general-purpose tasks. The o1 models use "reasoning" - they think step-by-step before answering, making them better for complex math, coding, and scientific problems, but slower and more expensive.
