GPT-4 vs GPT-4o: Which AI Model Performs Better in Coding and Reasoning Tasks

By Seifeur Guizeni - CEO & Founder

GPT-4 and GPT-4o differ notably in coding performance, reasoning, consistency, and user experience, with each showing strengths and weaknesses that affect practical use.

When it comes to coding, users often find GPT-4 less prone to repeating mistakes. GPT-4o tends to apologize if corrected but may make the same error again. This behavior makes GPT-4 a more reliable assistant for programming tasks. Benchmarks suggest GPT-4 Turbo can outperform GPT-4o slightly, but GPT-4o is not consistently better across all coding challenges. Many users perceive GPT-4 as an experienced coder offering varied solutions, while GPT-4o is seen as a junior coder stuck on repetitive approaches.

Overall coding reliability favors GPT-4. Users describe it as easier for problem-solving and producing fewer errors. However, current deployments sometimes do not clarify which model powers a session, leading to unpredictable experiences.

In terms of model behavior, GPT-4o struggles more with hallucinations and repetitive loops. When stuck, it requires extensive guidance to recover. This looped, single-minded behavior harms performance with complex or creative instructions, an essential aspect of GPT tasks that demand nuanced responses. GPT-4o also tends to be more verbose and less responsive to specific instructions to be concise or direct. This can frustrate users who prefer succinct answers.

Regarding reasoning and complex instructions, GPT-4 generally outperforms GPT-4o. GPT-4 has a stronger ability to handle intricate instructions, analyze data, and deliver logical solutions. In contrast, GPT-4o sometimes fails to execute multi-step reasoning effectively, which diminishes its usefulness in scenarios requiring higher cognitive processing and creative output.

GPT-4o demonstrates advantages in specific areas. It excels at additional actions beyond pure text generation, such as performing detailed algorithmic computations and conducting external data operations. These capabilities help it reduce errors and hallucinations in tasks involving calculations or iterative processing. In some cases, even smaller variants like GPT-4o Mini outperform their larger siblings, revealing nuances in performance depending on task design. Occasionally, GPT-3.5 Turbo may also be superior on particular benchmarks.

User preferences often lean toward GPT-4 Turbo for smartness and ease of interaction. Users describe GPT-4o as “talkative” and prone to producing repetitive outputs, which may hinder efficient workflows. The irritation extends to GPT-4o’s tendency to generate lists unnecessarily, despite user instructions to avoid this format. A common request is for OpenAI to allow users explicit choice between models to better suit their needs, as current options are somewhat opaque and inconsistently organized.

Benchmark results are difficult to interpret due to potential “cooked” data that does not necessarily reflect real-world application. Experts advocate for independent, scientific testing to obtain objective performance measures and validate claims made by commercial deployments.

Specific performance differences illustrate the points above. For example, GPT-4o once correctly identified the answer “pepper” in a test but no longer consistently does so. In contrast, GPT-4 Turbo reliably produces the right result even when not given examples. This difference highlights GPT-4 Turbo’s superior consistency and understanding in practical tasks involving reasoning and knowledge.

Let’s unpack this rivalry with some juicy details gathered from real user experiences and technical insights.

The Coding Showdown: GPT-4 Dances Past GPT-4o

Coding tasks demand precision and adaptability. According to users, GPT-4 acts like a seasoned coder who offers diverse approaches to problems. Meanwhile, GPT-4o reminds them of a “talkative junior coder”—superficial and prone to repeating the same mistakes even after being corrected.

Imagine you’re debugging a gnarly piece of code. You point out a mistake to GPT-4o; it apologizes but stubbornly repeats the same error. Frustrating, right? GPT-4, however, listens better, makes fewer mistakes, and navigates toward solutions without getting stuck.

Benchmarks show GPT-4o has a slight edge sometimes, but these gains are inconsistent and often only marginal. Real-world usage tells a clearer story: GPT-4 is more dependable and consistent, especially under complex coding demands.

Loops, Hallucinations, and Verbosity: GPT-4o’s Quirks

One glaring problem that users report with GPT-4o is its tendency to get trapped in “annoying loops”—repeating phrases or ideas endlessly, much like a parrot with a limited vocabulary. It often requires excessive “handholding” to snap out of these cycles.

Plus, GPT-4o can be “annoyingly verbose” and seems to have selective hearing. Ask it to keep things brief, and it might ignore you just to keep talking—reminding you of that friend who never stops sharing stories, no matter how hard you hint it’s time to wrap up.

This verbosity can slow down workflows and cloud the clarity needed for precise instructions, especially critical in professional environments.

Complex Tasks: GPT-4’s Superior Reasoning and Instruction-Handling

When the going gets tough—complex logical instructions, multi-step reasoning—GPT-4 flexes its mental muscles better than GPT-4o. Users who have compared them note that GPT-4o stumbles more, missing nuances in instructions or failing to generate a variety of thoughtful responses.

For tasks demanding creativity and reasoning, GPT-4 remains the more reliable companion. GPT-4o, in contrast, tends to deliver surface-level output, lacking the depth necessary for sophisticated problems.

GPT-4o’s Secret Weapon: Extra Actions and Algorithmic Prowess

Now, it’s not fair to count GPT-4o out. It’s occasionally better at performing “additional actions” like writing specialized algorithms or executing certain data-gathering operations outside the usual transformer model.

For example, when it comes to calculations, GPT-4o’s results are often more accurate thanks to these advanced features, helping to cut down hallucinations or outright errors.

Interestingly, the smaller GPT-4o Mini model sometimes outperforms its bigger sibling—a quirky reminder that size and power don’t always guarantee dominance. Even GPT-3.5 Turbo outshines GPT-4o in a handful of cases.

What About User Preference? Spoiler: GPT-4 Turbo Wins Hearts

Given all this, many users flock toward GPT-4 Turbo—not just over GPT-4o, but over most alternatives. Why? Because it’s smarter and easier to collaborate with during problem-solving sessions. It listens, adapts, and doesn’t annoy users with repeated blunders or an endless wall of text.

The frustration with GPT-4o runs deep. Imagine telling your AI not to produce lists, and it still bombards you with them. Or worse, the sudden switch to GPT-4o mid-chat throws off the flow. This unpredictability drives many to demand more control: “Let us choose which model our GPTs use!” they plead.

Are Benchmarks Truthful? A Call for Independent Testing

Don’t trust the shiny scores alone. Benchmarks often feel “cooked,” failing to reflect the messy reality of daily use. Without transparent, independent testing of commercial models, users and developers are left guessing which AI truly fits their needs.

Think of it like buying a car based only on horsepower numbers without taking it for a real drive through traffic. You want hands-on proof, not just flashy figures.

Real-Life Example: The “Pepper” Puzzle

Here’s a concrete test: GPT-4o once nailed the answer to a tricky question (pepper) but lost consistency over time. GPT-4 Turbo, by contrast, gets it right every single time—even when it’s not given an example.

This difference highlights one big truth: Reliability beats occasional flashes of brilliance.

Wrapping Up: Which Model Should You Choose?

So, what’s the verdict in the GPT-4 vs. GPT-4o face-off? If you want consistency, fewer mistakes, and more thoughtful responses, GPT-4 and GPT-4 Turbo take the crown. They are the equivalent of experienced mentors guiding you smoothly through complex projects.

If you crave aggressive performance on specific algorithmic operations or like experimenting with newer features, GPT-4o is worth a spin—just be ready for some repetition and frustration on the side.

Ultimately, every AI has its quirks, but knowing their strengths lets you pick the best assistant for your unique tasks. Wouldn’t it be nice if OpenAI gave users the power to pick and choose transparently? Until then, testing and patience remain your best strategies.
