OpenAI’srecently launched o3 and o4 - mini AI modelsare state - of - the - nontextual matter in many respects . However , the unexampled manakin still hallucinate , or make things up — in fact , they hallucinatemorethan several of OpenAI ’s older model .
hallucination have proven to be one of the biggest and most unmanageable problems to solve in AI , impactingeven today ’s best - performing systems . Historically , each Modern model has amend slenderly in the hallucination department , hallucinate less than its predecessor . But that does n’t seem to be the case for o3 and o4 - mini .
allot to OpenAI ’s internal tests , o3 and o4 - mini , which are so - call abstract thought models , hallucinatemore oftenthan the company ’s previous abstract thought models — o1 , o1 - miniskirt , and o3 - mini — as well as OpenAI ’s traditional , “ non - thinking ” models , such as GPT-4o .
Perhaps more concerning , the ChatGPT maker does n’t really have it away why it ’s happening .
In its expert study foro3 and o4 - mini , OpenAI writes that “ more inquiry is needed ” to understand why hallucinations are getting bad as it scale up logical thinking models . O3 and o4 - mini perform better in some areas , include tasks related to coding and math . But because they “ make more claim overall , ” they ’re often result to make “ more accurate claim as well as more inaccurate / hallucinated claim , ” per the report .
OpenAI find that o3 hallucinated in reply to 33 % of questions on PersonQA , the company ’s in - house benchmark for measuring the accuracy of a model ’s knowledge about people . That ’s roughly double the hallucination rate of OpenAI ’s previous reasoning models , o1 and o3 - mini , which scored 16 % and 14.8 % , respectively . O4 - mini did even bad on PersonQA — hallucinate 48 % of the time .
Third - partytestingby Transluce , a nonprofit AI research lab , also found grounds that o3 has a tendency to make up action it took in the process of arriving at answers . In one lesson , Transluce keep o3 claiming that it run code on a 2021 MacBook Pro “ outside of ChatGPT , ” then copied the numbers into its result . While o3 has access to some creature , it ca n’t do that .

“ Our surmise is that the variety of reenforcement learning used for o - series models may hyperbolize issues that are usually mitigated ( but not fully score out ) by standard post - training pipelines , ” said Neil Chowdhury , a Transluce researcher and former OpenAI employee , in an email to TechCrunch .
Sarah Schwettmann , co - laminitis of Transluce , supply that o3 ’s hallucination pace may make it less useful than it otherwise would be .
Kian Katanforoosh , a Stanford adjunct professor and CEO of the upskilling startup Workera , told TechCrunch that his team is already testing o3 in their coding workflows , and that they ’ve discover it to be a step above the rival . However , Katanforoosh say that o3 tends to hallucinate broken site data link . The model will add a link that , when clicked , does n’t work .
Hallucinations may aid modeling arrive at interesting idea and be originative in their “ thinking , ” but they also make some good example a tough sell for business organisation in market place where truth is preponderating . For example , a law firm belike would n’t be proud of with a model that inclose lots of actual errors into client contract bridge .
One promising approach to hike up the truth of fashion model is giving them web search capabilities . OpenAI ’s GPT-4o with web search achieves90 % accuracyon SimpleQA , another one of OpenAI ’s truth benchmarks . Potentially , lookup could improve abstract thought simulation ’ hallucination rates , as well — at least in font where substance abuser are uncoerced to disclose prompts to a third - political party search provider .
If scaling up reasoning model indeed continues to worsen hallucination , it ’ll make the hunt for a solution all the more urgent .
“ Addressing hallucination across all our models is an ongoing sphere of research , and we ’re continually form to ameliorate their truth and reliability , ” say OpenAI voice Niko Felix in an e-mail to TechCrunch .
In the last year , the unsubtle AI industry has pivoted to focus on reasoning models aftertechniques to ameliorate traditional AI framework started showing diminishing return . logical thinking better model performance on a potpourri of chore without requiring monumental amounts of computing and information during grooming . Yet it seems reasoning also may lead to more hallucinating — exhibit a challenge .
