OpenAI Pricing

OpenAI’s pricing is dynamic and may change at any time. For the most current rates, please visit openai.com/pricing.

OpenAI categorizes its foundation models into three primary types—text, image, and audio—each charged using a distinct unit:

Model Category	Billing Unit	Basis
Text	1,000 tokens	~750 words per 1,000 tokens
Image	Per generated image	Cost varies by image resolution
Audio (Whisper)	Per second of audio	Charged by duration (transcription/translation)

A token corresponds to roughly 0.75 English words. Tools like tiktoken help estimate token counts before you send requests.

Text-Based Use Cases

Text models support a variety of tasks, each billed per 1,000 tokens:

Use Case	Description
Word/Code Completion	Predictive text or code generation
Chat	Conversational AI interactions
Embeddings	Semantic vector generation
Fine-Tuning	Custom model training
