💾 LLM Architecture Cheat Sheet: from GPT-2 to Trillion-scale Models

LLM Architecture Gallery — a page with cards for 39 models (2019–2026): DeepSeek, Qwen, Llama, Kimi, Grok, Nemotron, and others. For each — an architecture diagram, decoder type (dense / sparse MoE / hybrid), attention type, and links to technical reports and configs from HuggingFace.

It's clear how the market has converged on MoE + MLA for large models and why hybrid architectures (Mamba-2, DeltaNet, Lightning Attention) are gaining momentum.

⚠️ ¿Te estás perdiendo la mayor transferencia de riqueza de esta década?
Seamos honestos... Mientras la mayoría de personas están entreteniéndose preguntándole tonterías a ChatGPT, una pequeña minoría silenciosa ya está facturando miles de euros extra cada mes. Y no, no son programadores ni gurús.
Simplemente tienen la información correcta mucho antes que el resto.
La Inteligencia Artificial avanza a una velocidad que asusta. Cada mañana sale una nueva herramienta, una nueva actualización o una startup que destruye un nicho entero y crea 3 oportunidades de negocio millonarias nuevas.
¿El problema? Leer las 500 noticias aburridas en inglés sobre servidores y APIs para encontrar esa pepita de oro que realmente puedes usar para ganar dinero hoy... es imposible si tienes un trabajo y una vida.
Por eso he creado este rincón privado. 👇
He programado un investigador de Inteligencia Artificial que no duerme. Él lee y mastica automáticamente todas las aburridas publicaciones científicas de OpenAI, Silicon Valley y TechCrunch... y te envía directamente a tu móvil solamente lo que importa:
🔥 El Resumen: Qué herramienta acaba de salir al mercado.
💡 El Impacto: Por qué esto va a cambiar las reglas del juego.
💎 LA MASTERCLASS: Un Plan de Acción B2B paso a paso y "Masticado" sobre cómo puedes TÚ monetizar esa misma noticia esta misma tarde. Ni humo ni teoría, solo negocios aplicables.
Ya no hace falta que persigas la información; ahora las oportunidades de negocio caen directamente en la palma de tu mano mientras te tomas el café.
👉 Toca aquí para entrar gratis al Canal donde ocurre la magia antes de que cierre las puertas:
🔗 https://t.iss.one/iamonetizacion
P.D. Dentro del canal encontrarás el acceso a nuestro Club VIP Cerrado, donde literalmente te entrego las Masterclass de ingeniería de negocio que la IA me genera en exclusiva. Entra y compruébalo tú mismo. 🚀
