GPT-3.5 Turbo Fine-Tuning Pricing Overview

GPT-3.5 Turbo 4K Fine-Tuning
-
Cost for 1,000 input tokens:
- 3x less
- $0.012
Thoughts/Ideas:
- This indicates a significant cost reduction, making it more affordable for users to input data for fine-tuning. The reduction by three times can suggest optimization in processing or scaling efforts.
- Fine-tuning with more tokens could potentially lead to higher precision and better accuracy for specific tasks.
-
Cost for 1,000 output tokens:
- 2x less
- $0.016
Thoughts/Ideas:
- Output tokens generally reflect the model's generative capacity. A reduction in cost by two times is a practical benefit for users who rely on generating extensive outputs, such as in content creation or detailed response generation.
GPT-3.5 Turbo 16K Fine-Tuning
-
Cost for 1,000 input tokens:
- 4x less
- $0.003
Thoughts/Ideas:
- An even lower cost for input tokens compared to the 4K fine-tuning signifies a more optimized model for handling high-volume data inputs. This could be particularly advantageous for large-scale data integration or enterprise-level applications.
-
Cost for 1,000 output tokens:
- 2.7x less
- $0.006
Thoughts/Ideas:
- The greater reduction for output tokens in the 16K model indicates a model designed for more efficient text generation. This could mean better handling of complex queries, richer outputs, and improved performance for applications requiring detailed response generation.
Summary of Pricing Information
| Fine-Tuning Model | Input Tokens Cost Reduction | Input Tokens Cost | Output Tokens Cost Reduction | Output Tokens Cost |
|---|---|---|---|---|
| GPT-3.5 Turbo 4K | 3x less | 0.016 | ||
| GPT-3.5 Turbo 16K | 4x less | 0.006 |
Additional Information:
- The usage of "4K" and "16K" seems to refer to different fine-tuning configurations or capacities, potentially representing the maximum token limits or specific batch sizes used during the fine-tuning process.
- Cost reductions signify improved efficiencies, which could impact both small-scale and large-scale use cases, encouraging broader adoption and facilitating diverse applications.
