Anthropic Core Workflow B — Streaming & Batches

Overview

Two complementary patterns: real-time streaming for interactive UIs (SSE events via POST /v1/messages with stream: true) and the Message Batches API (POST /v1/messages/batches) for processing up to 100,000 requests asynchronously at 50% cost reduction.

Prerequisites

• Completed anth-install-auth setup
• Familiarity with anth-core-workflow-a (Messages API basics)
• For batches: understanding of async/polling patterns

Instructions
