Planvio is an open-source, self-hosted project management platform with an AI agent that can actually take action, not just chat. It combines project management, governed AI execution, permissions, approvals, audit logs, and autonomous workflows in one system. It’s built with Laravel and can run on ordinary cPanel shared hosting without Docker or root access.

AI reasoning is only one part of building a production-ready system. The harder problems appear after the model responds: managing context, calling tools safely, handling failures, maintaining state, enforcing policies, observing execution, recovering from partial failures, and turning probabilistic decisions into reliable real-world outcomes. This article explores the engineering architecture required to make AI systems dependable at scale.

Agentic AI is changing how systems communicate. Explore why the OSI model may need Layer 8 and Layer 9 for identity, cognition, semantics, and meaning.

The OSI model was designed for an Internet of Information, where networks move data between deterministic endpoints. As Agentic AI introduces autonomous systems that communicate, collaborate, and exchange context, data transport alone may no longer be enough. This article explores the idea of extending the OSI model with Layer 8 and Layer 9 to address identity, cognition, semantics, and the exchange of meaning between AI agents.

This story was originally published on HackerNoon at: https://hackernoon.com/tokens-per-watt-why-your-context-window-is-a-power-decision. On an H100, tokens per watt drops 12x between 4K and 64K context. Agents live at the fat end of that curve. The fix comes from semiconductor architecture.

A March 2026 paper derives what its authors call the 1/W law: tokens per watt halves every time the serving context window doubles. On an H100 running Llama-3.1-70B, that's 17.6 tok/W at 4K context and 1.50 tok/W at 64K. Same silicon, roughly 12x worse efficiency, purely from context length (arXiv:2603.17280). Agents are the single worst workload for that law, because a tool-calling loop re-sends its entire accumulated history on every step. Chip designers hit a structurally similar wall in 2004 and answered with power domains, DVFS, and clock gating rather than a better transistor. The translation to agent architecture is real. But it breaks in one specific place that's worth knowing about before you bet your GPU budget on it.
