A large-scale dataset of more than 1 million real-world user interactions with ChatGPT collected between April 9, 2023 and May 1, 2024.  It captures a wide range of languages (more than 68 languages detected), user prompts, and conversational contexts. The dataset was developed by offering free access to ChatGPT and GPT-4, with participants consenting to share their chat histories for research purposes. The data includes metadata such as time stamps, hashed IP addresses (coding an IP address for privacy), country/state, and request headers.

The dataset captures a wide variety of user prompts and conversation themes, including:

  • Creative / personal expression: Creative writing, role play, stories, poems.
  • Educational / homework-related queries: Help with school subjects, summarizing texts, etc.
  • Professional / work/business use: Drafting emails, presentations, business automation tasks, job seeking (résumés, interview prep).
  • Coding / technical questions: Writing, debugging, understanding code.
  • General information seeking: Factual questions, trivia, requests for definitions or explanations.
  • Language tasks: Translation, help with English, code‐switching, etc.
  • Health / advice / personal issues: Some amount of personal advice or health‐related queries.

To protect privacy, personal identifiers are removed, and toxic or sensitive content is flagged or filtered. Multiple versions of the dataset are available, ranging from full “in-the-wild” conversations to cleaner, curated subsets for safer analysis.

The wildchat database is relevant to the learn-and-work ecosystem:

  • Because the dataset spans many domains (education, work, personal, creative), it offers a rich resource for studying how people actually use conversational AI across contexts.
  • It supports research into language use (code switching, multilingual conversation), prompt design, user behavior, privacy issues, and ethics (e.g. handling toxic content).
  • It can inform the design of learning tools, tutoring systems, or workplace AI assistants: what kinds of queries do users naturally ask, what support they seek, what mistakes or misunderstandings arise.
  • It is useful for information science / library / digital literacy: how people search for information, phrasing of queries, how AI responds, what kinds of gaps or errors emerge.

A newer release, WildChat-4.8M, extends the collection period through July 31, 2025, expanding total conversations to more than 4.8 million. This version broadens coverage beyond ChatGPT to include interactions with other open-query reasoning models, such as o1-preview and o1-mini. Like the earlier release, it preserves user privacy through de-identification methods and provides both raw and curated subsets for safe and responsible research use.

The datasets are publicly hosted on Hugging Face by the Allen Institute for AI. It is released under a research-only license, making it freely accessible for study, evaluation, and non-commercial research. Access to subsets containing toxic or sensitive conversations is gated and requires approval to ensure responsible use.
