Leetcode Wizard vs. ChatGPT: A Comparison

While ChatGPT can allegedly pass a Google coding interview and land a $183K salary, it’s not the most reliable way to go about your coding interview and practice. That’s where Leetcode Wizard comes in, offering a better and more consistent way to ace coding interviews. Here’s how.

ChatGPT has a couple of limitations. The chatbot itself recommends users to double-check output because it can and will make mistakes. These mistakes happen because the output always has a randomized element, which produces both correct and incorrect output. And due to the nature of large language models, it’s not unheard of to run into hallucinations. This randomness makes it tricky to depend on ChatGPT when you're using it for coding interviews, where accuracy is essential.

Another issue is that ChatGPT’s knowledge only covers information up to a certain point. So if you're working on a newer coding problem, like one that was added to Leetcode websites after ChatGPT was last updated, it may not be able to solve it correctly or might not even recognize the problem.

Leetcode Wizard is built specifically for solving coding interview problems, and our model is trained on a daily basis with the newest Leetcode problems. This makes it a more reliable tool for practicing, preparing for, and use during job interviews.

Leetcode Wizard delivers higher pass rates with a customized GPT-4o model

Leetcode Wizard uses a modified version of the GPT-4.0 model, while the free version of ChatGPT runs on GPT-3.5 and GPT-4o-mini. The biggest difference here is that Leetcode Wizard’s model is optimized specifically for solving (complex) leetcode problems.

Unlike standard versions of ChatGPT, Leetcode Wizard’s AI has been trained on a custom Leetcode problem set. This tailored training allows it to handle both basic and advanced coding challenges more efficiently. By focusing on real and up-to-date leetcode problems that are common in practice and interviews, the AI is equipped to understand problem structures, recognize patterns, and deliver more accurate, optimized solutions compared to generic models like ChatGPT 3.5 or even GPT-4o-mini. This makes Leetcode Wizard a far more reliable option for high-stakes environments like coding interviews, as opposed to ChatGPT.

In addition to training the model on Leetcode problems, Leetcode Wizard runs the generated answers through a custom-developed humanizer. This extra layer ensures that the AI’s responses appear more natural, like those written by a human, rather than machine-generated text. This step adds to Leetcode Wizard being undetectable on coding interview platforms and ensuring that users can rely on the tool without risking detection.

Another key advantage of this modified GPT-4.0 model is its ability to generate better solutions, especially for more difficult problems. While the free version of ChatGPT can struggle with tougher Leetcode questions, Leetcode Wizard’s specialized model has a much higher success rate. This is because the AI has been fine-tuned to prioritize accuracy and efficiency, making it far more capable of handling the kinds of complex logic and algorithmic problems that interviewers often present. This accuracy will only increase with the new OpenAI o1 version, which we are watching closely and will use once it’s available to the public.

Leetcode Wizard is convenient to use

Leetcode Wizard offers a user-friendly experience by eliminating the need for manual screenshots, which are necessary when using ChatGPT, making it more convenient in comparison. Instead of relying on the user to take and upload screenshots of coding problems, Leetcode Wizard’s AI automatically inspects and analyzes the problem for you.

After the Leetcode Wizard AI inspects your problem, you receive a list of possible algorithms that can be used to solve the problem. These are sorted from worst to best time complexity, so you can quickly identify the most efficient solution.

Another major advantage of Leetcode Wizard is its ability to handle any problem, known and unknown. Unlike ChatGPT, which may struggle with newer problems. This is especially important for FAANG interviews, as these companies often refresh their interview questions to keep them unique and challenging. Many of these questions can’t easily be found on the internet, but Leetcode Wizard is able to provide at least one possible algorithm for every problem it encounters.

Leetcode Wizard is fully hidden and undetectable during coding interviews

Leetcode Wizard also has an advantage against ChatGPT for coding interviews because it can be controlled by undetectable hotkeys, which means you never have to leave the window where your coding interview is taking place, making it undetectable. Most screen-sharing softwares can’t capture it, and Leetcode Wizard is invisible in all screenshots.

The hidden functionality makes it particularly useful during interviews. With the step-by-step guidance, even the toughest leetcode problems can be solved. To further ensure not being detected, there’s also a separate webview, which can be opened from the desktop application. This allows users to view all output on another device, e.g., your phone, tablet, or laptop. Make sure to place this second device close to your code input to prevent suspicious eye movements. Some screen-sharing software circumvents the OS flags we set to hide the desktop application. Using the web view guarantees you'll be 100% safe.

ChatGPT doesn’t offer the option to operate fully hidden. So, in comparison, on all points: Leetcode Wizard is the better option. We’ve got your back.
