RONKONKOMA, N.Y. - s4story -- PhantomByte, an AI R&D studio specializing in sovereign AI infrastructure and autonomous agent systems, announced its daily technical publication has crossed 156 articles. Accompanying this milestone is an expanded Gumroad library featuring six new advanced deep dives: Agent Containment Engineering ($14.99), Hardening Your Agent Against Prompt Injection ($24.99), Stop Burning Tokens ($24.99), The Harness Effect ($24.99), Building Model-Agnostic Agent Architecture ($14.99), and Which Model Should I Run ($7.99), alongside beginner guides starting at $0.99.

"Most AI tutorials teach you what a model is. We teach you how to stop one from burning your budget," said founder Vinny Barreca. "Every advanced guide comes from a production failure we hit, diagnosed, and fixed."

The studio operates on local-first infrastructure built on Ollama, Hermes Agent, and OpenClaw—eliminating token billing and cloud dependencies. PhantomByte's footprint includes 20+ live sites on Google Cloud Run, 64 custom agent skills, and 12 hands-on PDF tutorials.
