The Batch Issue 351: Andrew Ng on Modern AI Prompting — Extended Thinking, Tool Use, and Document Context
Andrew Ng's weekly editorial explains how prompting has fundamentally changed since 2022 — covering extended reasoning, document-level context, tool integration, and a new course teaching these techniques across major AI platforms.

Andrew Ng explains how prompting in 2026 looks nothing like 2022 — and what you need to learn.
What is it?
The Batch's weekly editorial by Andrew Ng covering the evolution of prompt engineering from basic ChatGPT-style prompting to modern techniques including extended reasoning, tool calling, document context, and multi-platform usage.
How does it work?
Ng outlines how each new LLM capability — reasoning tokens, long context, tool APIs — requires different prompting mental models, and introduces a new DeepLearning.AI course that systematically covers the updated toolkit.
Why does it matter?
Most developers are still using 2022-era prompting patterns with 2026 models, leaving significant capability on the table. This piece maps exactly what's changed and why it matters.
Who is it for?
