1. Foundations & Theory

#	Post	Problem Tackled	Key Takeaway
1	Why Is GPT Better Than BERT? A Detailed Review of Transformer Architectures	Confusion over the practical differences between decoder‑only (GPT) and encoder‑only (BERT) models.	Decoder‑only models excel at generation because they predict the next token autoregressively, while encoder‑only models shine on classification and token‑level tasks.
2	Decoding Transformers' Superiority over RNNs in NLP Tasks	Legacy belief that recurrent networks are still competitive for sequence work.	Self‑attention removes the sequential bottleneck, enabling parallel training and better long‑range dependency capture.
3	Scaling Laws in Large Language Models	Unclear how model size, data, and compute interact.	Performance follows a predictable power‑law; doubling compute yields diminishing returns, guiding budget allocation.
4	Primer on Large Language Model (LLM) Inference Optimizations	High latency and cost of serving LLMs.	Techniques like KV‑cache reuse, quantization, and fused kernels can cut inference cost by up to 70 %.
5	Mamba Architecture: Can It Beat Transformers?	Need for more memory‑efficient sequence models.	Mamba replaces self‑attention with state‑space layers, offering linear‑time scaling for very long inputs.
