Personal engineering lab by Rohit. Deep dives into agentic AI, self-hosting, and building at the edge.https://gekro.com/en-us11652coral@gmail.com (Rohit Burani)11652coral@gmail.com (Rohit Burani)https://gekro.com/blog/token-economics/https://gekro.com/blog/token-economics/Rohit argues that owning the inference layer pays for itself at every scale, from a solo home lab up to a 50,000-user enterprise. He breaks down why cloud API costs grow linearly with adoption while owned-hardware costs plateau, why pre-training a model from scratch is a multi-million-dollar trap nobody outside frontier labs needs to fall into, and how Parameter-Efficient Fine-Tuning collapses the customization cost to a few hundred dollars on a single consumer GPU.Thu, 07 May 2026 00:00:00 GMT11652coral@gmail.com (Rohit Burani)AI EngineeringArchitecturehttps://gekro.com/blog/sonic-phoenix/https://gekro.com/blog/sonic-phoenix/Rohit built Sonic Phoenix, a seven-phase pipeline that used acoustic fingerprinting, language classification, and metadata enrichment to extract a structured catalog from 7,246 chaotic audio files - then deleted the 30GB of audio and shipped the metadata as an AI skill for on-demand Spotify playlist curation.
