About 0degrees.ai

0degrees.ai is a blog for engineers who want to build with AI — not just read about it.

The name is the idea: start from zero. Every article begins at first principles and works up to something you can ship. We cover the full arc of modern AI engineering — large language models, autonomous agents, retrieval-augmented generation, prompt engineering, evaluation, and the tooling that ties it all together.

The field moves fast, and most content is either marketing or academic. We aim for the gap in between: practical, current, and honest. Working code, real trade-offs, and the failure modes nobody mentions.

What we write about

• Fundamentals — Core concepts every AI engineer should internalise first.
• Agents — Designing, building and orchestrating autonomous LLM agents.
• RAG — Retrieval-augmented generation, embeddings and vector search.
• Prompt Engineering — Reliable prompting patterns for real production systems.
• Tooling — The frameworks, SDKs and dev tools that ship AI faster.
• Production — Evals, observability, cost and reliability at scale.
