In this solo walkthrough, Eric Siu demonstrates how he leverages the GPT‑6 Astra model to automate virtually every aspect of his marketing operation. He begins by showing AI‑edited video output that achieved a 7.2% click‑through rate and 8,600 views, then walks through how Astra repurposes that video into short‑form clips, Midjourney‑styled teasers, and carousel posts. Siu uses Astra to scan the web for high‑performing short‑form formats, generate a dynamic format library, and automatically schedule posts via Metricool and ManyChat. He conducts strategic channel analysis of competitors (e.g., Nate Herk) to extract reusable workflow patterns, then builds those patterns into “skills” that are published to his public Skills Dojo and shared with his team. He also creates gated GPT‑6 landing pages using Beehive MCP for email capture and newsletter opt‑ins, and shows how to spin up such sites on demand. Throughout, he discusses infrastructure considerations—choosing which machine runs the agents, managing computer‑use rules, and handling website lead‑leak detection for Single Grain and Single Brain sites. Siu outlines a prioritization system (P0‑P4) for daily tasks, demonstrates automated website audits that surface form‑field and CTA issues, and emphasizes handing off repeatable AI‑driven workflows to team members so humans focus on the 1% of work that requires judgment. The video ends with a call‑to‑action to explore his AI‑marketing services at Single Grain and Single Brain.
