GPT（生成式预训练模型）的费用取决于其提供方。由OpenAI提供的GPT模型（如GPT-3）收费基于每个使用API调用的价格。OpenAI的收费模型是基于每个token（单词或字符）进行计费的。具体的定价细节可以在OpenAI的网站上找到。
需要注意的是，GPT模型的使用费用可能会因为不同的使用情况而有所不同，例如不同的应用场景、使用频率等。因此，在使用GPT模型之前，最好查阅相关提供方的定价细则，以确保了解使用模型所需支付的费用。
OpenAI’s GPT-3 pricing model is determined by the number of tokens used in API calls. Tokens refer to the individual words or characters in a text. Each API call consumes tokens for both input and output.
As of March 1, 2023, the following prices apply for GPT-3:
- For the pay-as-you-go (PAYG) pricing, it costs $0.10 per token.
- For the subscription pricing, different tiers are available with discounted token prices, ranging from $0.06 to $0.08 per token.
It’s important to note that prompt engineering techniques can be used to control the number of tokens required for the desired response. Additionally, there may be other costs associated with API requests, such as network charges.
For the most up-to-date and accurate pricing information, it is recommended to refer to OpenAI’s pricing page or contact OpenAI directly.
