curious about one thing: are you gonna code or just master prompt engineering? over the years, i've found that really determines if you should use Sololearn or something else for ur commute tho!

Seconding the recommendation above! Brilliant is legit. Also check out Elements of AI—it's a free course that, I mean, simplifies neural network logic for commuters without ur usual math. Helped me years ago.

Warning: DONT download those generic "AI Assistant" apps!! They're basically just overpriced wrappers that wont teach you the tech. I mean, AI is actually just complex pattern matching via transformer architectures. Knowing this makes ur prompts wayyy more effective! Here's what I recommend:
- Brilliant: I used this, amazing visual lessons!!
- Elements of AI: fantastic fundamentals.
- Google Cloud Skills Boost: great for commute-sized modules... I LOVE it, definately worth it!

I'm still a bit of a newbie here, but I spent way too much time comparing different platforms last week lol. I'm really budget-conscious, so I've been looking at how the big brands compete for our attention. Ngl, it’s confusing how many 'free' apps actually just want your credit card info for a trial. I ended up finding a few things that actually stay free while I've been digging through the specs:
- Microsoft Learn: Their 'AI for Beginners' path is surprisingly non-technical. It explains the 'how' without drowning you in code, and the modules are pretty short. - AWS Skill Builder: They have this thing called 'Cloud Quest' which is literally a game. It's a bit of a battery hog on mobile but way more engaging than a textbook. - Cognitive Class.ai: This one is backed by IBM. It’s a bit more formal, but the lessons are bite-sized enough for my bus ride. Basically, I feel like the big tech companies provide better data for free because they want people using their tools later, you know? It’s a weird market. Do you think it’s better to stick with one brand's ecosystem or jump around to see the different ways they build their models? Anyway, just my experience so far!

I totally agree with the point about those sneaky 'free' trials that just want your card info. Tbh, it’s much better to go the DIY route and use platforms where you can actually see what’s happening *under the hood* without a paywall. I'm still a bit of a newbie too, but I've been looking at the technical specs of models lately and it’s honestly fascinating how they work. Anyway, here are a few things I’ve been using that are actually free:
- Enki: This app is great for my commute because it feels like a game but covers actual AI and data science fundamentals.
- Kaggle Learn: They have these 'micro-courses' that are super short. I started the 'Intro to Machine Learning' one and it explains things like model validation and *underfitting* really well tho.
- Hugging Face: It’s more of a platform than an app, but checking out their 'Tasks' section helps me understand what different AI models actually *do*. I’m still trying to wrap my head around things like 'inference' and how many billions of parameters a model actually needs to be 'good,' but these help. Has anyone else tried looking at the open-source stuff or is that too advanced for a start? I'm still learning too lol.
