CS224N Lecture 19: How Small Models Can Move Beyond Brute-Force Scaling

The final lecture frames Open Questions in NLP 2026 as smart scaling: prolonged RL, Prismatic synthetic data, RL as pretraining, and open collaboration seek reasoning gains beyond adding parameters.

Stanford CS224V Lecture 14: Scaling Language Models When Data Is the Bottleneck

The final lecture is not a complete LLM-training tutorial. It studies data efficiency under fixed data and abundant compute, revisiting epochs, batches, ensembles, self-training, and conditions for synthetic continued pretraining.

CS336 Lecture 14: Filtering, Deduplication, and Mixing Turn Raw Web Data into Training Data

Lecture 14 moves raw documents through language, quality, and safety filtering; exact and near deduplication; and source mixing. Each stage reshapes model behavior, while synthetic instruction and agent trajectories extend the pipeline into executable environments.
