Seems that you're right! Also, not that I doubted they were using OpenAI, but searching for `"finish_reason"` on the web all point to openai docs. Personally, I wouldn't say it's a very common attribute to see in logs generally.

https://platform.openai.com/docs/api-reference/introduction

Right there in the docs:

> Now that you've generated your first chat completion, let's break down the response object. We can see the finish_reason is stop which means the API returned the full chat completion generated by the model without running into any limits.

Regarding how training data ends up in logs, it's not that far fetched to create a trace span to see how long prompts + replies take, and as such it makes sense to record attributes like the finish_reason for observability purposes. However the message being incuded itself is just amateur, but common nonetheless.

The OpenAI API is basically the gold-standard for all kinds of LLM companies and tools, both closed and open source, regardless of whether the underlying model is trained on OpenAI or not.

Not just the gold-standard, but also a de-facto standard - most of the proprietary and OSS tools I've seen that let you configure LLMs only implement support for OpenAI-compatible endpoints.

Wish AWS would support it in bedrock.
