In the constantly evolving realm of AI generated content the veracity of information is of utmost importance. With a couple of fact checking solutions available, discerning their efficacy becomes crucial. Originality.ai, revered for its transparency and accuracy in AI content detection had recently ventured into the domain of fact checking but how does our solution stack up against well established giants like ChatGPT or emerging contenders like Llama-2? This study aims to answer this question.
Summary of Findings:
The article compares 6 AI models for fact checking: Originality.ai, GPT-4, GPT-3.5, CodeLlama-34b, Llama-2-13b, and Llama-2-70b.
A dataset of 120 recent facts (60 true, 60 false) was created and fed to each model to test accuracy.
Originality.ai’s Fact Checking Aid has the highest accuracy at 72.3%. GPT-4 was second at 64.9%.
GPT-4 and CodeLlama-34b had high rates of returning "unknown", making them unreliable for fact checking.
Originality.ai stood out with 0% "unknowns" and low error rate, indicating reliability.
When fact checking a generated article, Originality.ai caught more false facts than GPT-4 and Llama-70b.
Originality.ai's strength is fact checking for content creators, providing sources and explanations.
Originality.ai performed well on recent general knowledge facts and aims to continue improving its fact checking capabilities.
What is Fact-checking?
Fact-checking is the rigorous process of verifying the accuracy and authenticity of information presented in various forms of content whether that be news articles, blogs, speeches or even social media posts. In an age where information can be shared at lightning speed the spread of misinformation can have profound consequences, from influencing public opinion to endangering public health and safety.
The importance of fact checking is multifold:
Upholding trust: Reliable information forms the basic foundation of trust between content creator, news organizations and their audience. Fact-checking ensures that the information shared is accurate maintaining the credibility of these entities.
Informed decision making: Accurate and up to date information enables individuals to make informed decisions about life based off of the content found across the media.
Preventing misinformation spread: Fact-checking acts as a filter preventing the spread of false narratives and misconceptions that can potentially have an overwhelming negative impact on the public.
Promoting accountability: It holds public figures, journalists, and content creators accountable for their statements, ensuring they are responsible in their communications and discouraging the spread of false information.
LLM Hallucinations
When we discuss fact checking using LLMs we would be amiss to not discuss hallucinations which are defined as “a confident response by an AI that does not seem to be justified by its training data.”1
Here are the hallucination rates for some of the popular LLMs found from Anyscale

The Methodology
Crafting the dataset: At the heart of this study lies the dataset, a carefully selected collection of 120 different facts. Let’s break down the composition:
True facts (60 items): These statements grounded in reality were gathered from trustworthy and reliable sources.
False facts (60 items): These statements were crafted to oppose the true facts, theses statements while seeming credible are fundamentally flawed.
It’s worth noting that ALL the facts contained within this data set are facts from 2022-onwards.
Each of these 60 facts was fed into the AI-powered fact checking solutions, Originality.ai, GPT-3.5-turbo, GPT-4, Llama-2-13b, Codellama-34b and Llama-2-70b.
The main goal?
To measure the accuracy of each tool in distinguishing fact from fiction
Gathering the Responses
For each fact checked we logged the response from the tool. The responses fell into one of 3 categories
True: The tool marked the fact as true
False: The tool marked the fact as false
Unknown: The tool was unable to verify the fact true or false
Error: The tool did not provide a response
In the scenario involving Originality.ai, when the provided explanation was at odds with the isTrueClaim value, the explanation was regarded as the accurate source of information.
Analysis
After collecting the data the primary metrics under the microscope were:
Accuracy: The ration of facts correctly identified as true or false.
False positives: Occasions when False facts were incorrectly identified as True.
False negatives: Situations where True facts were incorrectly identifies as False.

Unknown = The model return the result ‘unknown’
Error = The model returned an error
Analysis of results:
In an analysis of the 6 AI models on a dataset of 120 facts, Originality.ai achieved the highest accuracy at 72.3%. GPT-4 followed with a respectable 64.9%.
GPT-4 had the highest unknown rate at 34.2% followed by CodeLlama-34b with 27.5% making them both unreliable for the purposes of fact checking. Both Llama2-70b and Originality.ai had the lowest unknown rate at 0%.
When it comes to error rates Llama-2-70b had the highest at 3.3% while Originality had a modest 1.7%. Notably the rest of the models did not return any errors.
Lower unknown rates are preferable for reliable fact checking. Originality.ai and Llama-2-70b stand out in this regard with 0% unknowns. High error rates or unknowns such as that in Llama-2-70b or GPT-4 could pose a challenge in the real world as their use cannot be relied upon.
Use Originality.ai’s Fact Checking Aid to Help Fact Check AI or Human Text
This testing however is not where Originality.ai shines, Our fact checking tool was built with content editors in mind which is why we include sources and an explanation when using our graphical interface.
We used ChatGPT-3.5 to generate a short article about a very recent news event, Iwe then passed that information to Originality.ai’s tool.
