Control tags (non-AI)

These tags are not about AI. They are a control, and they fall too, so fashion in one ecosystem cannot explain the decline.

AI tags — LLM wave

Stack Overflow creates a tag some months after the tool it names. In a tag's first year, part of the rise comes from people who learn the tag.

Stack Overflow merged the chatgpt and openai tags into this tag. The merge also moved the old questions, so the 2020–2022 months are complete.

LangChain shipped in October 2022, but Stack Overflow created the tag in early 2023. The 2023 rise is partly that late start.

AI tags — vendor (noise-level)

These tags peak at 1–9 questions a month. The flat line is the result; the small moves are random.
