As artificial intelligence continues to advance, developers are increasingly turning to large language models (LLMs) to assist with programming tasks. Two of the most prominent models in this space are the newly released Claude 3 Opus, developed by Anthropic, and the well known ChatGPT-4 AI model, created by OpenAI. In this guide, we will take an in-depth look at how Claude 3 Opus vs ChatGPT-4 compare when it comes to writing code, focusing on their features, performance, and overall utility for developers.
Code Refactoring
One common programming task where LLMs can be particularly helpful is code refactoring. In a head-to-head comparison, Claude 3 Opus demonstrated a clear advantage over ChatGPT-4. Given a task to refactor TypeScript code to use a discriminated union instead of throwing errors, Claude 3 produced cleaner and more readable code by separating the union types into distinct type aliases. This approach made it easier to understand which properties corresponded to the success and error cases, especially when dealing with more complex unions.
In contrast, ChatGPT-4 opted to put everything in a single type alias, resulting in less readable code that could become difficult to maintain if there were multiple states or properties involved. Moreover, while Claude 3 correctly removed the error throwing in favor of returning the appropriate union case, ChatGPT-4 missed the point of using a discriminated union by still throwing an error in one place.
Context Retention and Code Conversion
Another area where Claude 3 Opus shined was in its ability to retain context and handle code conversion tasks. When provided with a JavaScript file and asked to perform multiple refactorings (renaming a function, avoiding useEffect misuse, removing a redundant function, and converting to TypeScript), Claude 3 successfully accomplished all the requested changes. It even demonstrated strong context retention by using the same naming conventions from a previous example.
Furthermore, when given a new JavaScript file and tasked with converting it to a factory component with a switch statement, Claude 3 not only converted the code to TypeScript but also imported and utilized the correct types from an earlier example. This showcases the model’s ability to maintain context across different code snippets and apply it appropriately.
Adherence to Best Practices
In a test involving a React component that misused useEffect, both Claude 3 Opus and ChatGPT-4 suggested adding an autoDownload argument to control the component’s behavior. However, ChatGPT-4’s suggested name, autoDownloadIfMissing, was more descriptive than Claude 3’s autoDownload.
Despite this, Claude 3 demonstrated a better understanding of React best practices by pointing out that using useEffect was an anti-pattern in this particular case. In contrast, ChatGPT-4’s solution still relied on useEffect. Moreover, Claude 3’s code was cleaner and more efficient, as it referenced an existing download function instead of repeating the download logic like ChatGPT-4 did.
Conciseness and Relevance
When it comes to presenting code solutions, conciseness and relevance are key factors. In this regard, Claude 3 Opus had the upper hand. Its responses focused on the relevant changed code, making it quicker and easier for developers to parse and understand. On the other hand, ChatGPT-4 tended to repeat the full code in its answers, which could be less efficient when dealing with larger codebases.

Scoping and Unintended Side Effects
In further iterations of the React hook example, Claude 3 demonstrated a better understanding of code organization and avoiding unintended side effects. It kept its suggested changes scoped within the hook, maintaining a clear separation of concerns. Conversely, ChatGPT-4 moved some of the logic to the consuming component, which didn’t make sense in the given context.
Moreover, when provided with a hint to initialize state based on whether a file already exists locally, Claude 3 updated the hook’s logic to behave correctly. ChatGPT-4, however, introduced an unintended side effect that prevented re-downloads, which could be problematic in certain scenarios.
Integration and Accessibility
While Claude 3 Opus shows great promise for coding tasks, it’s worth noting that ChatGPT-4 currently has wider integration into integrated development environments (IDEs). This makes ChatGPT-4 more convenient for developers to use for mundane tasks like generating boilerplate code. However, for more complex refactoring and code organization tasks, Claude 3 Opus appears to be the stronger choice.
