OpenAIは日本時間の9月19日未明に、gpt-3.5-turbo-instructが利用可能になったというeメールを配信した。eメールによればこの最新の製品は、text-davinci シリーズなどの以前の Instruct モデルと同様の方法でトレーニングされた InstructGPT 3.5 クラス モデルだ。ただし、ターボモデルと同等の速度であり、大幅なアップグレードとなるという。
We are excited to announce the release of gpt-3.5-turbo-instruct, our latest model that serves as a replacement for several deprecated models, such as text-davinci-003.

Key Features:
Gpt-3.5-turbo-instruct is an InstructGPT 3.5 class model. It’s trained similarly to previous Instruct models such as the text-davinci series while maintaining the same speed as our turbo models.

We are committed to making cutting-edge technology accessible, so we have priced gpt-3.5-turbo-instruct in line with our other turbo GPT-3.5 models with 4K context.

Thank you for being a part of our journey and for building with OpenAI. Your support enables us to continually advance and bring you the best in AI technology.

Best regards,
The OpenAI team
