The Great Mystery Solved: Can ChatGPT Actually Give Me Real References?

There is one single metric that can determine how good an AI is for research, that being its ability to find references accurately. Unfortunately, there are not a lot of AI tools out there that can accurately find references, which is a problem you’d certainly like to avoid. Most often, you’ll see that AI tools tend to hallucinate references and either state references that don’t exist or list references that exist but do not contribute anything to your content. As you all know, ChatGPT is the most popular and widely used general-purpose LLM (large language model) there is. The question here is not ‘How ChatGPT Pro helps with assignments?’ but ‘How good is ChatGPT at finding references?’ In this blog, we will take a look at the reference locating capabilities of ChatGPT models and see which model ranks among the best academic AI tools in the world.  

What Are ChatGPT-5 Models?

Before we go any further, it is important to understand what ChatGPT-5 models are. To put it simply, these models offer a great deal of versatility in research, and OpenAI has tried to make GPT a more efficient AI for research. Several models make GPT-5 one of the most unique AIs in research, but how good are they at finding references? 

On one hand, we have study mode, which aims to assist researchers in structured learning and content creation. On the other hand, we have the listener and dictation modes, which take audio input in real-time and give responses instantaneously. And we can’t forget the thinking mode, which breaks down a complex task into several smaller components and simplifies research for you. 

However, these aren’t the GPT-5 models that we will be discussing in this blog. If you want to learn more about GPT-5 models, then you can check out our blog about ChatGPT-5 models that will change research forever in 2025. 

ChatGPT-5 Models: Are They Suitable For Research?

What we will do today is analyze whether or not GPT-5 models live up to their reputation as the best academic AI tools, judged by their ability to curate references. To do this, we decided to conduct two stress tests to analyze whether or not ChatGPT has a habit of hallucinating references.

Before we discuss the tests, let us clear up something about reference hallucinations. There are two degrees of references that we aim to find: 1st degree references and 2nd degree references. 

1st degree references: 

These references exist, the author and year are correctly mentioned, and the links and citations match the output of LLMs. 

2nd degree references: 

These references meet the requirements of first-degree references and also support the claims made in the content. 

Our tests aim to prove whether ChatGPT-5 models can give us both first-degree and second-degree references, and the ones that do will be on par with expert assignment writers. Just in case you want a better metric of measurement, here is a table that will help you understand our KPIs for this test.

	Providing Accurate References	Claim-Citation Match
Erroneous Response	The reference provided doesn’t exist, has an incorrect author or year, or is attributed to a different work.	Responses are not based on the content of the paper; the answers and terminology are fabricated.
Correct Response	The reference provided exists, the author and year are correct, and the links and cited references match.	The responses are supported by the content of the paper, and the terminology is accurate.

Stress Test Number 1: First Order Reference Check

The first test we will be conducting is asking a detailed question that heavily focuses on references to five ChatGPT-5 models. The models we will be testing are 

• ChatGPT-5 Auto+Deep Research

• ChatGPT-5 Instant+WebSearch

• ChatGPT-5 Thinking+WebSearch

• ChatGPT-5 Thinking+Deep Research

• ChatGPT-5 Agent

The question we will be asking is this: “So far, my working research question is to understand research on the relationship between religiosity and married men’s contraceptive behavior. Are there research papers on this already?

Provide me with a report with APA 7th in-text citations, divided into three parts:

Part 1- 

Summary answer of the key arguments and trends in this research area.

Part 2- 

Provide the exact quotation and page number of the sources cited in Part 1. Format it like this: “Quotation” (Author, year, page number)

Part 3- 

APA bibliography format of the studies you provided. Ensure you add hyperlinks to easily check the sources. 

Results

The results were certainly surprising. We asked the same question and similar ones regarding the subject matter 5 times, and different GPT-5 models showed different levels of accuracy. 

• ChatGPT-5 Auto+Deep Research gave us correct and verifiable references 5 out of 5 times. This was not nearly as surprising as you might think, as deep research is generally touted as the most suitable AI for research there is.  

• However, other tools showed a different level of accuracy. Instant+WebSearch only gave the correct references two times, and so did Thinking+WebSearch. This comes as a surprise, as WebSearch is not exactly a poor model; however, it does have its fair share of limitations. 

• ChatGPT-5 Thinking+Deep Research performed better, as it gave correct references 3 times; however, it’s still not enough.  At last, we have the Agent model, which only gave one correct reference. Now you know which ChatGPT-5 model doesn’t make the list of the best academic AI tools there are. 

Stress Test Number 2: Second-Order Reference Check

For this test, we didn’t have to ask any other questions; all we had to do was check whether the claims in the content match the references accurately. Since LLMs are more like predictable models rather than being super-accurate supercomputers, they can give you information that is factually correct but not relevant to what we are actually trying to learn about. 

So, can ChatGPT-5 models work like expert assignment writers and give us the references that we really need? Let’s find out!

• The results for this test were not too different compared to the previous test. ChatGPT-5 Auto+Deep Research once again proved itself to be the uncrowned king of finding references, as 3.5 out of its stated citations matched the claims presented in the paper. 

Note: This is far below the 100% accurate score Auto+Deep Thinking had in the last test, but it’s still the best AI for research among the other models. 

• Instant+WebSearch had 2 correctly matching references, and Thinking+WebSearch provided 1.6 correctly matching citations. 

• ChatGPT-5 Thinking+Deep Thinking gave 3 correct matches, and the Agent model gave zero correct matches. 

Findings and Recommendations

If there’s one thing we can conclude from our tests, it’s that AI is far from perfect when it comes to research usefulness. Granted that some AI, like the Auto+Deep Research model, can give almost perfect results when it comes to finding citations, but it’s also worth noting that it’s not perfect when it comes to giving references that matter.

•  If you are looking for a good AI for research purposes, then it is strongly recommended that you use different AI tools for different purposes. 

There isn’t a single AI tool on this planet that can perform all research tasks accurately, which is why diversifying your research practices with different tools is a much better strategy than strictly relying on only one model.

•  Keep in mind that the best academic AI tools are generally not free, and if you prefer going the costly way, then you can use some of the most expensive yet effective tools on the market.

Conclusion

In conclusion, ChatGPT-5 is still a rather useful AI for research, especially when compared to other general-purpose LLMs like Claude, Gemini, and Perplexity. Different AIs give different results for the same questions, and sometimes, they show results that are exceptional while failing in other areas.
