Building with Anthropic Claude: Prompt Workshop with Zack Witten

Aug 17, 2024 · 1:34:56

In this live prompt engineering workshop, Anthropic's Zack Witten and Jamie Neuwirth demonstrate techniques for improving Claude prompts in real time, using the Anthropic console. They show that XML tags clearly separate prompt sections, that placing instructions after information improves adherence, and that prefilling assistant responses with opening JSON or tags reliably forces JSON output without preamble. Witten advises using stop sequences and code to handle formatting rather than over-prompting, and emphasizes that few-shot examples—especially contrastive pairs with reasoning—drive more improvement than any other technique. The workshop covers role-playing multiple personas by routing via code, mitigating hallucinations by extracting quotes before summarization, and grading translations with chain-of-thought and fine-grained examples.

Alex Albert, Head of Developer Relations at Anthropic, argues the industry is in a 'magic star icon phase'—tacking AI onto existing products—and urges rebuilding from the ground up. He announces Claude 3.5 Sonnet, which scores 64% on pull request evals (vs 38% for 3 Opus), with 200k context, vision improvements, and pricing at $3/M input and $15/M output tokens. New features include Artifacts for collaborative creation of code and React components from screenshots, Projects for team knowledge grounding, and an enhanced ToolUse API supporting hundreds of tools and structured JSON output. Future models (3.5 Haiku/Opus) will be smarter, cheaper, and faster; a steering API for interpretability allows clamping feature values to control outputs.
