“A tiny student model trained on a giant teacher's guesses often beats one trained on real labels alone.”
“Adding 'take a deep breath' to your prompt measurably improves LLM accuracy on math problems.”
“Most LLM benchmarks are now contaminated because the test data was inside the training set.”
“Models that see images don't merge vision and language — they translate pixels into token-like embeddings first.”
“Multimodal models don't translate images into text first — vision and language share the same token space from the start.”
“Without activation functions, stacking 100 neural network layers is mathematically identical to having just one.”
“The term 'Artificial Intelligence' was coined in 1956 before anyone had built a working transistor-based computer.”

“Fine-tuning a model on just 1,000 examples can outperform a model trained on billions of raw tokens.”
