    Dissecting Claude Code — An Architecture Deep Dive

    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.

    Post-Training in LLMs — From SFT to Reasoning RL

    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.

    Three AI Trends Reshaping 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.

    What I mean when I say love.

    Aftersun, Alcestis, and philia helped me understand love as attention, reciprocity, and the courage to let another person remain fully themselves.
