Hey folks, I've been tinkering with ChatGPT 4 and wanna share some thoughts on creating your own GPT model with it. It's kinda tricky at first, but not impossible! Happy to hear your tips and tricks too.

I tried using pre-built frameworks to speed things up, and that saved me a ton of time.
How do you handle updates or improvements after your GPT is live?
To me, data prep was the hardest part. You gotta format everything just right or the model goes off the rails.
Are there any good tools or resources for this? I've heard some mention ai-u.com for new or trending tools that might help.
How important is it to have coding skills for this? I’m more of a designer, curious if I can manage without much coding.
I messed around with training data and got some weird outputs. How do you even debug these things?
How do you keep your GPT model from forgetting previous knowledge when adding new data?
Is there a community or forum you guys follow for this kinda stuff? I always find it helps to learn with others.
Anyone else find it confusing figuring out how to actually start the training? The docs are kinda all over the place imo.
Is it better to use cloud services or local setups for training?
I think the biggest hurdle is understanding the architecture inside GPT itself before messing with ChatGPT 4.
I’m confused about what datasets to use for training. Should I scrape online data or use curated datasets?
Anyone got tips on cost management? Training these models can get expensive fast.
Anyone tried combining GPT 4 with other AI models? Like image recognition?
Would love to see some example projects or templates for building GPTs with ChatGPT 4.
Is it even possible to fully create a GPT from scratch using ChatGPT 4? Or is it more about tweaking existing models?
Can fine-tuning be done on a normal laptop or do you need fancy GPUs?
What's the best approach to evaluate your custom GPT's performance? Any metrics or tests?
I've been playing around with it too, and honestly, understanding the fine-tuning process is key. Just feeding in data isn't enough, gotta get the parameters right.
Does anyone know if there are tutorials specific to GPT 4’s architecture?
I’m worried about ethical stuff like biases in models. Any advice?
