Can anyone help me with cost comparison / differences between completion API and chat completion API. I am using Azure open ai gpt3.5K 16K model
In my chart, cost is per 1 million tokens so you can compare the prices more easily:
Model | Training | Input usage | Output usage | Context Length |
---|---|---|---|---|
GPT-3.5-turbo-base | $n/a | $1.50 | $2.00 | 4k |
GPT-3.5 Turbo fine-tune | $8.00 | $12.00 | $16.00 | 4k |
GPT-3.5-turbo-16k | $n/a | $3.00 | $4.00 | 16k |
GPT-4 | $n/a | $30.00 | $60.00 | 8k |
-------- | ------------- | ------------- | ------------- | ------------- |
babbage-002 base | $n/a | $0.40 | $0.40 | 16k |
babbage-002 fine-tune | $0.40 | $1.60 | $1.60 | 16k |
-------- | ------------- | ------------- | ------------- | ------------- |
davinci-002 base | $n/a | $2.00 | $2.00 | 16k |
davinci-002 fine-tune | $6.00 | $12.00 | $12.00 | 16k |
(text-davinci-003) | (legacy) | $20.00 | $20.00 | 4k |
The last two sections are completion models.
