Inside Garry Tan's G-Brain: The Open-Source Repo YC Wants Every Company to Clone
Tom Blomfield told founders to build 'Garry's G-Brain, but for every business in the world.' We opened the repo, read the code, ran the benchmarks, and found four architectural bets that rewrite how agents should handle memory, routing, and self-maintenance.

I Audited an AI Agent Against the OWASP Agentic Top 10 — Here's What Survived
Everyone is shipping AI agents. Almost nobody is auditing them. I walked one codebase against all ten OWASP agentic threats — here's what held up, what didn't, and what your agent is probably missing.

The LLM Wiki Pattern: Giving Your Agent Persistent Memory
Instead of stuffing the context window every session or relying on stateless RAG lookups, let your agent maintain a living knowledge base about your project. Here is how to build it.

MemPalace vs. RAG: Four Architectural Patterns That Make Flat Vector Search Look Lazy
An open-source AI memory system built by a Hollywood actress and a crypto engineer — sounds like a gimmick. But the spatial hierarchy, zero-token ingestion, and 30× compression dialect are genuinely clever engineering.

Why Your AI App Crashes: Circuit Breakers for LLM Pipelines
Exponential backoff was fine when your database was local. Your LLM API is not. Here's the distributed systems pattern that keeps your architecture online when Anthropic goes down.

The LLM Wiki: A Compounding Knowledge Base
Most RAG systems rediscover knowledge from scratch on every query. Instead, you can configure your LLM to passively build and maintain a structured, interlinked wiki that gets smarter every time you drop a file into it.

Building a Doodle Detector with Gemini Embedding 2
What if you could draw a rough shape on a screen and have an AI instantly recognize it? We break down how to orchestrate Gemini Embedding 2 and ChromaDB to build a real-time multimodal vector search application.

Building an Autonomous Podcast with Gemini Flash 3.1
With the release of Gemini 3.1 Flash, the absolute latency barrier for conversational AI has been shattered. Here is a demonstration of how we used its real-time continuous capabilities to orchestrate a fully autonomous, zero-human-input podcast.

I Built a High School Where 48 AI Agents Live, Fight, and Break Down — No Writers Allowed
No scripts. No writers. 48 autonomous AI agents navigate senior year at Westbrook High — and the emergent behavior is more honest than anything a human writer would draft.

Autonomous Loop: The 'Dumb Zone' and the Ralph Loop Solution
Technical excellence in 2026 is no longer measured by the code you write, but by the autonomous loops you direct. We break down the fundamental shift from passive AI to Agentic AI.
