Pi is an open-source terminal coding agent that deliberately ships without features most agents consider essential. This article examines why radical minimalism, a TypeScript extension system, and a tree-structured session model make it one of the most versatile coding agent frameworks available.
Four things I wish I had known at twenty — about starting before you're ready, choosing environments over prestige, staying connected without performing, and turning curiosity into completion.
A deep dive into Claude Code's open-source codebase, covering the three-level paradigm shift, the agent loop with 4-stage context compression, streaming parallel tool execution, 66+ built-in tools across 6 categories, the dual-call skill system, four-type memory taxonomy, and three multi-agent collaboration modes.
A detailed walkthrough of every major post-training paradigm for large language models, from basic SFT through RLHF, RLAIF, DPO, ORPO/IPO/KTO/SimPO, reasoning RL, Constitutional AI, and tool-use training — with formulas, trade-offs, and the modern multi-stage pipeline that leading models use in 2025-2026.
A deep look at three converging AI trends in 2026 — from half-duplex chat to full-duplex real-time interaction, from multi-modal input to world understanding, and from semantic reasoning to predicting and acting in the physical world.
