LangChain Meetup - Day in the life of a token in the European cloud: AI on sovereign infrastructure
An evening with evroc’s AI team on how they actually build with AI on sovereign European infrastructure: the tools in their chain, where AI genuinely speeds things up, where it gets in the way, and the guardrails that let a small team ship fast on high-stakes systems.
William Blomqvist from LangChain kicks things off with a short LangChain presentation. In the main talk, Simon tells the story through the eyes of token 2322, better known as the em-dash, one of the most famous (notorious?) tokens in the business. We follow it through a working day inside evroc’s European cloud: woken at 3am to help with an incident, drafting plans, writing code, all without ever leaving Swedish soil.
