Converts naturally occurring user feedback into preferred and dispreferred responses. Its pipeline detects satisfaction and dissatisfaction, constructs preference examples, and evaluates responses against checklists derived from the feedback.
WildFeedback contains 20,281 preference examples. Fine-tuned models improve on the paper’s alignment and checklist-based evaluations.
2024Exploration tools
Yuntian Deng, Wenting Zhao, Jack Hessel, Xiang Ren, Claire Cardie, Yejin Choi
Provides search filters and an embedding map for exploring WildChat and LMSYS-Chat-1M. Its case studies connect individual conversations to broader topic patterns and reproduce examples from research on journalism and personal disclosures.
The visual comparison identifies a Midjourney prompt-generation cluster in WildChat and a chemistry cluster in LMSYS-Chat-1M.
2025Evaluation
Chaoqun Liu, Wenxuan Zhang, Jiahao Ying, Mahani Aljunied, Anh Tuan Luu, Lidong Bing
Builds Southeast Asian evaluation sets from local sources and uses real conversations to test how closely they reflect everyday requests. WildChat and LMSYS-Chat-1M supply the Wild Queries comparison corpus after language checks, length limits, and filtering.
In embedding-based comparisons, the locally constructed SeaExam and SeaBench are closer to the observed query distribution than translated MMLU and MT-Bench.
2025Evaluation
Omar Shaikh, Hussein Mozannar, Gagan Bansal, Adam Fourney, Eric Horvitz
Analyzes how users and assistants establish mutual understanding, alongside Bing Chat and human-human MultiWOZ conversations. It releases grounding annotations, a forecasting approach, and RIFTS to test when assistants should clarify, ask follow-up questions, or proceed.
RIFTS contains 1,740 tasks. The evaluated assistants rarely take useful grounding initiative; forecasting-based prompting improves their performance.
2025User behavior
Sheshera Mysore, Debarati Das, Hancheng Cao, Bahareh Sarrafzadeh
Studies how users steer writing across successive turns. The authors label follow-up types, identify recurring collaboration patterns with principal component analysis, and relate those patterns to writing intents such as brainstorming, technical drafting, and long-form composition.
Seven collaboration patterns account for 80–85% of the variance in the analyzed follow-up representations; explicit positive or negative feedback appears in only a small minority of sessions.
2025Evaluation
Wentao Zhang, Woojeong Kim, Yuntian Deng
Introduces aggregative question answering: answering questions that require combining evidence across many conversations. WildChat-AQA pairs conversation text and metadata with inferred topics and keywords, and compares retrieval, fine-tuning, and the PROBE retrieval method.
The benchmark contains 6,027 questions over 182,330 conversations. PROBE improves over standard retrieval, with retrieval and reasoning errors remaining in the evaluated systems.
2025Evaluation
Saumya Malik, Valentina Pyatkin, Sander Land, Jacob Morrison, Noah A. Smith, Hannaneh Hajishirzi, Nathan Lambert
Builds a reward-model benchmark around previously unseen human prompts from WildChat, combining quality and topic filtering with manual verification. It evaluates reward models across factuality, precise instruction following, math, safety, focus, and ties, and studies how benchmark scores relate to best-of-N sampling and RLHF.
WildChat supplies the human-prompt domains: factuality (475), precise instruction following (160), math (183), and focus (495). The safety and ties domains use other prompt sources.
2025User behavior
Yuhan Liu, Michael J. Q. Zhang, Eunsol Choi
Examines the frequency, meaning, and usefulness of implicit feedback in real conversations. It separates feedback polarity from what users actually request, and tests whether regenerating responses with that additional context improves model training.
Feedback semantics help on MTBench but do not consistently improve the longer, more complex WildBench tasks; positive feedback alone can be a noisy training signal.
2025User behavior
Shengqi Zhu, Jeffrey M. Rzeszotarski, David Mimno
Introduces ReCCRE, which separates request content, context, assigned roles, and general expressions in user prompts. The study tracks how users phrase requests as they gain experience and over calendar time.
Users include more context in their requests over time, and individual users’ expression patterns tend to stabilize with experience.
2025Information access
Hideaki Joko, Shakiba Amirshahi, Charles L. A. Clarke, Faegheh Hasibi
Examines factual information conveyed by chatbot responses, including when the user's main task is editing or creative writing. It releases extracted claims and check-worthiness annotations to study information access beyond explicit questions.
WildClaims contains 121,905 extracted claims from 7,587 assistant utterances; estimated check-worthy-conversation prevalence varies substantially with the annotation method.
2025Safety
Kobra Khanmohammadi, Pooria Roy, Raphael Khoury, Abdelwahab Hamou-Lhadj, Wilfried Patrick Konan, Alexander Da Re, Nicholas Rebelo Melo
Examines the security and quality of code generated in real user interactions, together with user intent and follow-up behavior. The extended study also tests security-oriented prompting strategies using prompts derived from the observed logs.
Security concerns are uncommon in the analyzed user requests, even when generated code has detected problems.
2026Training
Hao Peng, Yunjia Qi, Xiaozhi Wang, Zijun Yao, Lei Hou, Juanzi Li
Trains reward models directly on implicit user feedback using ordinal regression. Its pipeline classifies feedback, filters ambiguous signals, and validates refusal cases before training; experiments examine calibration, cross-prompt score consistency, user diversity, and online DPO.
Broader user diversity improves reward modeling. WildReward models also improve online DPO results over the reward-model baseline tested in the paper.
2026User behavior
Christopher Potts, Moritz Sudhof
Relates inferred AI fluency to task complexity and conversational outcomes. The study compares active iteration, critical evaluation, and passive acceptance, and examines how these behaviors relate to visible and invisible failures.
More fluent users attempt harder tasks and show more visible failures, yet achieve greater success on complex work; less fluent users more often have failures without overt negative feedback.
2026Evaluation
Joseph Suh, Ayush Raj, Minwoo Kang, Serina Chang
Tests whether learning a user simulator from real conversations helps train assistants that work better with people. The study fine-tunes simulators on WildChat user utterances, trains assistants through simulated interaction, and evaluates them on WildBench and in a study with 283 participants.
The assistant trained with the learned user simulator wins 58% of comparisons against the initial assistant in the human study; training with a role-playing model yields 51%.
2026User behavior
Neel Gupta, Maria Antoniak, Melanie Walsh
Studies how people generate and consume fiction through chatbots, combining conversation classification with close reading of repeated story requests. The authors examine fanfiction, roleplay, and erotic fiction, and discuss how iterative generation can reshape the relationship between reader and writer. A companion viewer supports exploration of the fiction subset.
The study classifies 195,271 conversations (34%) as fiction. Sampling one conversation per inferred user reduces this share to 7.1%.
2026User behavior

Studies how the definition of a mental-health conversation changes prevalence estimates in WildChat-4.8M. A classifier scores topicality, help-seeking intent, clinical language, and affective risk, with validation against independently coded conversations.
The estimated share of mental-health conversations is 0.21% when the definition requires explicit help-seeking for an identifiable person, and 4.90% when any mental-health topicality qualifies.
2026User behavior
Advait Deshmukh, Nora Benedict, Melanie Walsh, Maria Antoniak
Introduces WildStories, containing 275,635 story prompts, and WildEdits, containing 24,291 reconstructed edit trees. The study follows revisions across separate conversations, organizes edits by direction and narrative target, and uses this framework to generate story-prompt variations for evaluation.
94.2% of prompts with an identified parent link to a different WildChat conversation, showing how story revisions span separate conversations.
