Stack Overflow

New questions per month on Stack Overflow and across the Stack Exchange network, since 2015: tags for LLMs and for the earlier machine-learning wave, non-AI control tags, other Stack Exchange sites, answers, and derived shares.

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.

Artificial Intelligence SE

16 −20.0% yr as of Jun 2026

Stack Exchange started this AI site in August 2016. The zeros before that month are real.

Data Science SE

9 −82.4% yr as of Jun 2026

This is the other AI site on the network. Its questions fall too.

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.

artificial-intelligence

33 +57.1% yr as of Jun 2026

openai-api

3 −72.7% yr as of Jun 2026

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

4 −66.7% yr as of Jun 2026

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

large-language-model

8 −46.7% yr as of Jun 2026

github-copilot

2 −81.8% yr as of Jun 2026

huggingface-transformers

1 −90.9% yr as of Jun 2026

ollama

1 −66.7% yr as of Jun 2026

rag

7 +133.3% yr as of Jun 2026

This line counts only the rag tag, because retrieval-augmented-generation is a separate tag. The line stays at zero until April 2024.

llama

0 −100.0% yr as of Jun 2026

google-gemini

2 −85.7% yr as of Jun 2026

AI tags — ML wave

machine-learning

deep-learning

6 −60.0% yr as of Jun 2026

nlp

5 −37.5% yr as of Jun 2026

pytorch

10 −67.7% yr as of Jun 2026

tensorflow

6 −64.7% yr as of Jun 2026

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.

mistral-ai

0 as of Jun 2026

anthropic

1 as of Jun 2026

claude

3 +50.0% yr as of Jun 2026

Network-wide

These lines add up 19 sites, about 85% of the network outside Stack Overflow. The API gives no total, so the true total is higher.

Network excl. Stack Overflow derived

3.1k −55.6% yr as of Jun 2026

Whole network (incl. Stack Overflow) derived

5.3k −64.2% yr as of Jun 2026

Derived

AI-tool tags (sum) derived

32 −62.4% yr as of Jun 2026

This line adds up the 12 LLM tags. One question can carry several of them, so the true number is lower.

AI-tool questions, share of all derived

1.5% +34.4% yr as of Jun 2026

This line divides that sum by all Stack Overflow questions in the same month. Total questions fall fast, so the share can rise while AI questions fall.

Answers per question derived

2.9 +65.6% yr as of Jun 2026

This line divides all answers by all questions in the same month.
