# Show HN: TensorViz – Explore PyTorch models inside VS Code > Source: > Published: 2026-10-12 04:49:06+00:00 [START HEREExplore graph ResidualClassifier4-step tour TensorViz](https://tensorviz.dev/explore/residual-classifier/) ## The residual path What happens where the skip path rejoins? MODEL EXPLORER / CURATED BY TENSORVIZ 29 interactive PyTorch architectures. Follow a guided tour, inspect captured shapes, and take the source back to your own project. No installation · No Python needed CHOOSE A LEARNING PATH Start with attention, change one design choice at a time, then connect the pieces in LLaMA. Follow convolution, residual paths, U-shaped skips and image patches through landmark vision designs. Explore alignment, bidirectional pretraining, image–text pairing, low-rank adaptation and reasoning post-training. Compare the GAN game with noise prediction, latent-space denoising and a Transformer diffusion backbone. Inspect selective recurrent state, Evoformer sequence/pair coupling and promptable mask decoding. A teaching order, not a claim that each later model adopted every earlier idea. 29 models to explore Where does an image become a classifier input? How do queries, keys and values meet?

Component · 2014 How does a recurrent decoder decide which source positions to consult? Architecture · 2018 What changes when the encoder can see both left and right context? Training method · 2014 Which network is being updated, and what is it trying to change? Training method · 2020 How does a model learn to reverse corruption? Architecture · 2021 Why denoise a latent, and where does text enter? Architecture · 2022 What changes when a Transformer denoises latent patches? Where do the image and text meet? How do image features and a user prompt become a mask? How does the input decide what a recurrent state retains? How do sequence and pair representations interact before structure is produced? Training method · 2025 What changes in the learning process while the base architecture stays the same? Try another idea, or return to the full collection.
