Status: Ongoing project
Open source image generative model work to reproduce what Nano Banana can do.
- Users should be able to copy the notebook into Colab and train it by themselves.
- Current progress: trained with the world-renderer dataset for a sanity test.
- Next step: move to a larger dataset.

Status: Just started
A PPO reconstruction project focused on one practical question: what exactly in PPO makes RL training stable?
- Users should be able to copy the notebook into Colab and train it by themselves.
- Goal: implement every important PPO detail explicitly.
- Current progress: still at an early stage and not much has been finished yet.

A DDPM notebook project about why denoising does not become intuitive until you really inspect how the training process works.
- Users should be able to copy the notebook into Colab and train it by themselves.
- Main idea: do not assume the model learns denoising in an obvious way.
- Current progress: 300 epochs completed on a Colab T4; the tutorial includes saved digit samples, the training loss curve, and a runnable notebook.
