My Astro Notes

A walk through the major families of AI models — what they do, how they work, and what it takes to train them — for people who want intuition, not a textbook.

Learn how to use the waitForTaskToken callback pattern in AWS Step Functions to pause workflows without compute charges, achieving 98% cost savings on long-running async operations.

Learn best practices and techniques for writing effective prompts for small language models like Gemma and LLaMA, including evaluation methods and debugging strategies.

Discover how few-shot prompting works in AI by giving models just a handful of examples - and why this mirrors exactly how humans learn through pattern recognition and context.

Discover how training data shapes language models and why domain-specific knowledge compressed into model weights can dramatically improve reasoning in your field.

Large Language Models don't have opinions — they predict tokens.
