Literally one of the Worst models out there for writing code.
Not only does it Lag the whole webpage when writing code or reading files, but it does it in a Text format using Py, instead of it’s own IDE for handling CS files. Even when using it’s Coding specific tools it still makes the same errors.
- It has NO capabilities to debug, NO capabilities to detect context errors, NO capabilities to track file versions.
- Constantly refuses or contradicts my requests.
- Constantly prints nonsense/made-up functions and class names that have nothing to do with my code.
- Constantly confuses OLD file versions with NEW file versions leading to a huge sloppy mess of code, that I can only describe as Vomit.
Any time I use GPT5, with Pro features enabled mind you like Project Folders, i get a minimum of 10 Compile errors.
I did a side-by-side comparison of GPT5 with ClaudeAI. Claude is 100% better, there is no doubt, no debate - even on the FREE version. That’s the most painful part, Free Claude > GPT Pro. Makes me feel like I’m paying for a Scam.
- Where GPT5 always gives me dozens of compile errors. Claude gives me 0.
- Where GPT5 has no idea how to track file versions. Claude automatically increments the file version to avoid confusion.
- Where GPT5 often outright refuses to Read, or Double-Check, or Debug the code. Claude automatically does this in it’s backend, using what I can assume is it’s own IDE for compiling code.
Bottom line, GPT5 hallucinates and lies, it has no idea what it’s doing or why, has no IDE, it 100% relies on Guesswork and Assumptions instead of factual data.
The only drawback to using Claude instead of GPT5 Pro, I’ve experienced so far, is that Claude has a Usage Limit / Battery Life.
But I’m still switching to it until OpenAI fixes how GPT handles code, because right now it’s hot garbage.
Subscription cancelled.
If you’re wondering what inspired this rant… it was me arguing with GPT for the past 6 hours. I would upload my CS file, tell it to Analyze the code, give it a simple instruction based on the Error I had.
GPT would PRETEND to read the file, give me a bulls*t answer that had nothing to do with my code structure - inventing new classes and procedures that didn’t exist.
How do i know it didn’t read my new file? because it would quote Code from the CS I uploaded 3 versions ago.
