Two new paper implementations just dropped on TensorTonic.

Word2Vec: subsampling, skip-gram pairs, negative sampling, SGNS loss, CBOW forward, and a full SGD training step. The paper that started the whole embeddings revolution, built from scratch.

DenseNet: channel growth, composite layers, bottleneck layers, dense blocks with full feature map concatenation, transition layers, and the complete forward pass. The architecture that proved you don’t need to choose between depth and parameter efficiency.

GLM-4.5 is now on TensorTonic.

10+ problems covering partial RoPE, QK-Norm, group-restricted MoE routing, shared experts, multi-token prediction, and the full forward pass.

Implement it from scratch in PyTorch.

How cool would it be if you could visualize everything inside an ML model

[TensorTonic @TensorTonic]

Computer vision lovers, you need to see this.

We just shipped CV puzzles on TensorTonic covering everything from image operation basics and convolutions to pooling, losses, augmentation, and modern architectures all the way up to Vision Transformers.

Implement the full CV stack from scratch in Numpy and PyTorch.

Every ML framework eventually bottlenecks on GPU performance and when it does, the engineers who understand CUDA are the ones who fix it. Flash attention, fused kernels, custom triton ops, all of it starts with writing raw CUDA.

We just released 35 CUDA puzzles on TensorTonic, completely free.

Kernel foundations like vector ops and activations, matrix operations, tiled matrix multiplication, memory coalescing, shared memory, and reduction patterns. Write real CUDA C++ kernels and run them against tests on real GPU hardware.

Part 2/30 of the LLM Series: RoPE (Rotary Position Embedding)

How does a transformer know the difference between -
"the dog bit the man" and "the man bit the dog"?

The words are almost identical, but the meaning changes completely.

RoPE encodes position as rotation, allowing transformers to understand relative order through geometry.

@Spectator_seekr We don't offer courses.

[TensorTonic @TensorTonic]

We're starting a new series of LLM internals which will be interactive, cool visualizations into the techniques behind modern LLMs: attention variants, Flashattention, LoRA, RLHF, quantization and more.

We just released our first concept: KV caching in LLMs.

While its good to implement GPT2, LLaMA, DeepSeek but you should be able to implement classic ML algorithms as well such as linear regression, KNN, decision trees, random forests, PCA, K-means, Naive Bayes, and ridge regression from scratch.

These are the algorithms that show up in every single ML interview.

We shipped a full Classic ML track on TensorTonic with interactive visualizations where you can actually see your linear regression fitting in real time, watch KNN voting with draggable test points, and visualize PCA finding the direction of maximum spread. You implement the math, we show you what it looks like.

GRPO, DPO, PPO, RLHF are the algorithms behind every major LLM alignment pipeline and if you really want to understand how a base model becomes ChatGPT, you need to implement them yourself.

We just shipped a full RL track on TensorTonic covering all of it.

RLHF with KL penalties, DPO, GRPO, RLOO, PPO clipped surrogate, Actor-Critic, REINFORCE, GAE, all the way down to the fundamentals like DQN variants, Q-Learning, SARSA, Monte Carlo methods, and multi-armed bandits.

Every ML framework hides optimizers behind one line of code and nobody questions what’s actually happening when you call optimizer.step().

We have coding questions where you implement every optimization algorithm from scratch, starting from vanilla gradient descent all the way to AdamW.

SGD, momentum, Nesterov, Adagrad, RMSprop, Adam, and AdamW, each one building on the last so you actually understand why Adam exists and what the W in AdamW fixes.

NumPy is the backbone of every ML pipeline. Linear algebra for neural networks, matrix decompositions for PCA, vectorized gradient for backprop, feature engineering on tabular data.

We've released 25 problems on array creation, slicing, indexing, broadcasting across mismatched dimensions, and replacing slow Python loops with vectorized ops. The stuff that separates people who use NumPy from people who actually think in NumPy.

Stop reading. Start building

@TensorTonic is pure fire 🔥

Built for developers who prefer writing real code over just reading theory.

Practical. Focused. Implementation-first

Code > Theory: https://t.co/NyEq7VFx5N
