Here is how it works and why I kept it boring.Wed, 17 Jun 2026 00:00:00 GMTBuild LogRAGLegal TechPolicingPostgreshttps://sulabhsethi.tech/blog/how-gatishakti-works/https://sulabhsethi.tech/blog/how-gatishakti-works/After the Bhashini posts, a reader asked for the same treatment of PM GatiShakti. It is a very different kind of platform: not AI models, but one shared map for planning India's infrastructure.

A practical, honest look at what a single modest machine with no GPU can run, what it cannot, and how I host a whole platform on one small box.Fri, 12 Jun 2026 00:00:00 GMTSelf-HostingAIInfrastructurePractical GuideEdge AIhttps://sulabhsethi.tech/blog/how-bhashini-works/https://sulabhsethi.tech/blog/how-bhashini-works/Bhashini lets you speak in one Indian language and be understood in another. People assume it is one giant AI. It is not. A simple, fact-checked look at the real models behind it, the base model for translation, and how they were trained.Wed, 10 Jun 2026 00:00:00 GMTBhashiniAI4BharatMachine TranslationIndian LanguagesExplainerhttps://sulabhsethi.tech/blog/how-rag-works/https://sulabhsethi.tech/blog/how-rag-works/Large language models will confidently invent a law section that does not exist.
