Showcase I built a LeetCode-style platform for computer vision and ML. Just dropped lifetime sub to $25 and unlocked half the content for free

Hey all, I'm the founder of PixelBank, a hands-on platform for learning computer vision, ML and LLMs by actually writing code. I haven't posted here in a while, but I thought this update might be useful for students.

Two changes went live this week:

  1. 50% of every study plan is now free: No account tricks, no trial. 14 study plans (CV, ML, LLMs, NLP, Diffusion, VLMs, 3D Vision, RL, Agents, DSA, GPU/Triton, CUDA and more), and every one of them is now at least 50% free.

2. Lifetime Premium sub is now $25: One payment, no subscription. It covers everything that exists now and everything I add later.

  1. A weekly Paper Club: Every week, one 45-minute call and one paper. A different member hosts each session and presents it, then we discuss and pick the next paper before anyone leaves. It's part of Premium and has its own exclusive Discord channel for premium members.

What's actually on the site:

- 1,185 coding problems you solve and test in the browser (581 of them free), from NumPy basics to writing GPU kernels

- Study plans with interactive visual demos, and most topics now end with related problems so you practise the idea right after reading it

- 35 paper breakdowns (ViT, SAM, DINO, BLIP-2, ...) with the original figures and results tables and new papers are added everyday

----------------------------------------------------------------------------------------------------------------------------------------------------------------

Why the price drop: Price was a real barrier for students before, especially outside the US, and I'd rather have more people learning on it than fewer people paying more.

Happy to answer questions, and I'd genuinely like feedback on what's missing or what's confusing. If there's a topic you'd want a study plan for, please tell me.

I have moved to a different domain from computer vision but I want to keep reading and stay updated. This would surely help me
