Price receipt

We read OpenAI's own pricing page on Aug 24, 2026 and found gpt-3.5-turbo listed with a price on the same row — that read is where the number above comes from, recorded as a new model. We keep the page text we read; its content hash is ac8180a912.

Overview

The model that made chat-completions cheap, and still OpenAI's lowest-priced legacy GPT SKU. 16,385 context window, 4,096 max output tokens, text in and text out, September 2021 knowledge cutoff. The default snapshot behind the alias is gpt-3.5-turbo-0125. OpenAI's own guidance is to use a current small model instead, and it has announced an end of life for this one.
