Feedforward Networks in Transformers: Why Two Layers Boost Large Language Models

Feedforward Networks in Transformers: Why Two Layers Boost Large Language Models

Feedforward networks in transformers are the hidden force behind large language models. Despite their simplicity, the two-layer design powers GPT-3, Llama, and Gemini by balancing depth, efficiency, and stability. Here’s why no one has replaced it.

How Context Windows Work in Large Language Models and Why They Limit Long Documents

How Context Windows Work in Large Language Models and Why They Limit Long Documents

Context windows limit how much text large language models can process at once, affecting document analysis, coding, and long conversations. Learn how they work, why they're a bottleneck, and how to work around them.

Contextual Representations in Large Language Models: How LLMs Understand Meaning

Contextual Representations in Large Language Models: How LLMs Understand Meaning

Contextual representations let LLMs understand words based on their surroundings, not fixed meanings. From attention mechanisms to context windows, here’s how models like GPT-4 and Claude 3 make sense of language - and where they still fall short.
