Most AI routing in production doesn’t need an LLM. Here’s a CPU only approach, with a live workshop on Oct 30
a pattern i keep running into: a company needs to sort incoming requests (claims, tickets, documents), someone wires up a large model to do it, and it works until latency, cost and the odd broken response show up in production.
there’s a workshop on Oct 30 that builds the alternative, a router that runs on CPU, tells you how sure it is, and only calls an LLM for the cases that really need one.
Fri Oct 30, 9:30 AM to 12:30 PM ET, live and online, led by Ben Auffarth (AI consultant, best selling author, 15+ years in data science).
what you’ll build:
- a classifier on small bidirectional encoders (ModernBERT and LFM2.5 Encoder) instead of a generative loop
- few shot training with SetFit, 8 examples per class
- split conformal prediction, so every decision comes with a measurable error rate
- a LangGraph workflow with human approval gates for uncertain cases
- routing inference under 15ms, with no JSON parse failures at the routing step
runs on a laptop or free Colab, with runnable notebooks and intermediate Python.
Full details and the agenda in comments or ask in dm
curious how many of you have replaced an LLM step with something smaller and what happened.
