AI research laboratory are increasingly relying on crowdsourced benchmarking platform such asChatbot Arenato probe the durability and weaknesses of their latest models . But some experts say that there are serious problem with this approachfrom an ethical and donnish perspective .
Over the past few years , laboratory including OpenAI , Google , and Meta have turned to platform that levy users to help oneself evaluate upcoming models ’ capability . When a model heaps favorably , the lab behind it will often tout that score as grounds of a meaningful advance .
It ’s a blemished approach path , however , according to Emily Bender , a University of Washington linguistics prof and Centennial State - source of the book “ The AI Con . ” Bender takes particular topic with Chatbot Arena , which tasks volunteers with prompting two anon. models and selecting the reply they favor .
“ To be valid , a benchmark need to evaluate something specific , and it need to have fabricate validity — that is , there has to be grounds that the concept of involvement is well - specify and that the measurements actually link up to the construct , ” Bender say . “ Chatbot Arena has n’t show that voting for one output over another in reality correlate with preferences , however they may be defined . ”
Asmelash Teka Hadgu , the co - founder of AI firm Lesan and a fellow at the Distributed AI Research Institute , order that he thinks benchmarks like Chatbot Arena are being “ co - opted ” by AI labs to “ promote enlarged title . ” Hadgu direct to a late argument need Meta ’s Llama 4 Maverick example . Meta amercement - tuned a adaptation of Maverick to tally well on Chatbot Arena , only to deduct that model in favor of releasing aworse - performing variant .
“ benchmark should be active rather than electrostatic datasets , ” Hadgu enounce , “ distributed across multiple independent entity , such as organizations or university , and tailored specifically to decided use cases , like education , healthcare , and other landing field done by practicing professionals who use these [ manakin ] for oeuvre . ”
Hadgu and Kristine Gloria , who formerly led the Aspen Institute ’s Emergent and Intelligent Technologies Initiative , also made the case that model judge should be pay for their work . Gloria said that AI labs should pick up from the mistakes of the data labeling manufacture , which isnotoriousfor itsexploitativepractices . ( Some lab have beenaccusedof the same . )

“ In worldwide , the crowdsourced benchmarking process is worthful and reminds me of citizen science initiatives , ” Gloria enunciate . “ Ideally , it helps bring in extra perspectives to provide some depth in both the evaluation and all right - tuning of data . But benchmarks should never be the only metric for evaluation . With the manufacture and the excogitation proceed quick , benchmark can speedily become unreliable . ”
Matt Fredrikson , the CEO of Gray Swan AI , which incline crowdsourced red teaming cause for models , said that volunteers are drawn to Gray Swan ’s platform for a range of reasons , let in “ learning and practicing new science . ” ( Gray Swan also awards hard currency prizes for some tests . ) Still , he acknowledged that public bench mark “ are n’t a substitute ” for “ paid private ” evaluations .
“ [ D]evelopers also need to rely on internal benchmarks , algorithmic red-faced teams , and contracted red teamers who can take a more open - ended approaching or work specific domain expertness , ” Fredrikson say . “ It ’s important for both role model developers and benchmark creators , crowdsourced or otherwise , to communicate resolution clearly to those who follow , and be antiphonal when they are call into question . ”
Alex Atallah , the CEO of model marketplace OpenRouter , which lately partnered with OpenAI to grant users early access toOpenAI ’s GPT-4.1 mannequin , said undetermined testing and benchmarking of models alone “ is n’t sufficient . ” So did Wei - Lin Chiang , an AI doctoral student at UC Berkeley and one of the founders of LMArena , which maintains Chatbot Arena .
“ We certainly sustain the use of other tests , ” Chiang say . “ Our goal is to make a trustworthy , open space that mensurate our community of interests ’s preference about different AI models . ”
Chiang say that incidents such as the Maverick benchmark discrepancy are n’t the result of a flaw in Chatbot Arena ’s intention , but rather research laboratory misread its policy . LMArena has taken step to keep succeeding discrepancy from pass off , Chiang said , including update its policies to “ reinforce our commitment to average , reproducible evaluations . ”
“ Our community of interests is n’t here as unpaid worker or model tester , ” Chiang allege . “ hoi polloi expend LMArena because we give them an open , transparent position to hire with AI and give collective feedback . As long as the leaderboard faithfully reflects the community ’s voice , we welcome it being shared . ”
