Takeaway

AI engineering still lacks a canonical architectural pattern; evals, orchestration, and security are where production work lives beyond commoditized LLM calls.

Summary

  • swyx's conference opener proposes finding the 'standard model' for AI engineering — analogous to ETL, MVC, MapReduce — beyond just RAG
  • Candidate models discussed: Karpathy's LLM-OS (updated with MCP and multimodality), the LLM-SDLC where evals/security/orchestration are where customers actually pay
  • References Anthropic's 'building effective agents', OpenAI's swarm-style agents SDK, and his own descriptive top-down agent taxonomy
  • Argues AI News (a workflow, not an agent per Soumith) still delivers value, so the field should optimize for value over arguable terminology

Original description
Whether you call it a workflow or an agent, AI engineered applications are seeing user-input:LLM-call ratios go from 1:1 (ChatGPT) to 1:100 (Deep Research, Codex) and even 0:n (Ambient/Proactive agents). How does AI Engineering change as you build increasingly AI intensive applications?
