# ChatGPT

**Type:** Product (large language model). **Vendor:** OpenAI. **Canonical reference:** OpenAI product page / technical documentation.

ChatGPT, launched publicly by OpenAI in **November 2022**, plays **two distinct roles** in this source:

1. **Treatment / catalyst event** — its public launch marks the pivot point ("before vs. after") for the observed labor-market shifts in [[claim-post-chatgpt-demand-shift]]. It is the diffusion event that begins the bifurcation between [[concept-ai-automation-displacement]] and [[concept-ai-augmentation-complementarity]].
2. **Research instrument** — the authors actively used ChatGPT to categorize **over 19,000 job tasks** to assess automation potential, per the [[framework-task-categorization-scoring|task-scoring methodology]].

This dual role (both the thing being studied *and* the tool doing the measuring) is a notable methodological feature worth flagging to any downstream consumer.

**Enrichment note:** The November 2022 launch as the treatment benchmark is consistent across the working paper ([[entity-displacement-or-complementarity-paper]]), the World Bank ([[evidence-world-bank-labor-demand]]), Anthropic ([[evidence-anthropic-labor-study]]), and Yale ([[evidence-yale-budget-lab]]).
