I spent all day comparing Bard vs ChatGPT 4. Here are the results (Software Developer Questions)
(lemmy.ml)
I'm a software engineer at a startup with impossible deadlines - I've used GPT4 for months to generate huge amounts app/server code, and much like your IDE, once you learn to use these tools you don't want to go back to the days without it.
Speed
- Bard is very fast- similar to GPT 3.5 Turbo
- You need to multitask two GPT4 instances side by side to compensate for how slow GPT4 can be
Reliability
- Bard lies and makes up fake API calls more than GPT4
UI
- Bard UI is garbage - You have to keep manually scrolling down the chat window, and for some reason the largest button on the page is "stop" (???)
- You can tell Bard to modify its response to be longer/shorter and a few other options - I thought this would be useful, but it never ended up helping
Memory
- Bard has really short memory - Forgets details from last response!
- GPT4 memory is also unreliable, any details that are important you have to repeat
Intelligence
- GPT4 is objectively smarter
Internet Search
- GPT4 Internet search is garbage
- Bard has "Verify with Google" - I had high hopes for this, but never actually had a use for it
Willingness to give full code
- GPT4 is bad, but Bard is worse. Both need to be begged/threatened to return more than 100 lines of directly paste-able code.
Generating Useful Code
- Bard can give more concise medium complexity functions
Adding tougher features
- Bard hallucinates and lies
Dealing with lies
- When you tell GPT something doesn't work, GPT will try something else
- When you tell Bard something doesn't work, Bard will lie, claim to fix it, then give back the same code
Following Instructions
- GPT4 sometimes doesn't follow instructions, but improving the prompt will fix that. Bard will happily ignore instructions, as clear as they may be.
Summary:
- GPT4 is still objectively better than Bard. Quite frankly, the prompts Bard couldn't handle, GPT3.5 could.
- The cons of GPT can be worked around, but for Bard, it's almost faster to do it yourself. Unless Bard was used like Copilot for short 1-2 lines of autocomplete, I wouldn't trust it.
PS: If you're not using AI yet for development, I highly recommend it - It's like using an IDE instead of Notepad. AI can easily 2-3x your output, but you have to learn how it works so you can prompt it correctly, and you have be good at fixing its mistakes.
