Time AI-native escreve código que a IA consegue ler, gerar e validar. Significa design system como contexto, API como contrato zod/OpenAPI, tool definitions MCP e domain logic legível. Aqui vai o padrão com diagramas, exemplos TypeScript e anti-patterns.
Cache exato atende prompts determinísticos; cache semântico responde perguntas paráfraseadas via embedding. Aprenda a combinar os dois com prompt cache do provider, memória de conversa e invalidação correta.
Deep dive na destilação de conhecimento: como modelos chineses aprenderam com Claude/GPT-4 (e com a si mesmos, caso DeepSeek-R1), dark knowledge de Hinton, response vs logit distillation, por que treinar do zero custa $100M e como fine-tunar seu próprio modelo por $5 com QLoRA e Unsloth. Inclui pipeline completo de código e análise das polêmicas éticas/legais.
Observabilidade generativa não é log com texto bonito. É prompt completo, versão do modelo, tools usadas, latência, custo e veredito do eval no mesmo span. Fechamento da série LLMOps em Produção.
Loop Engineering muda o foco de prompts isolados para ciclos de hipotese, execucao, avaliacao e rollback. Este guia explica o padrao de Andrej Karpathy, como o Autoresearch funciona e como aplicar a ideia em software, SaaS e agentes reais.

nextjs · boilerplate
A white-label AI-first foundation for shipping SaaS products with Next.js, chat, RAG, memory, tenants, and documentation. The verified snapshot documents Supabase rather than MongoDB; that limitation is explicit. MongoDB, Redis, and RabbitMQ require a compatible integration/configuration.

An advanced white-label, multi-tenant AI-first foundation for accelerating products with Next.js, chat, RAG, memory, and documentation. The verified snapshot does not prove a distinct Ultra layer; that limitation stays explicit while provider, cache, and queue swaps remain visible.
