WMO (World Model Optimizer)
WMO (World Model Optimizer) is an open-source CLI that turns an agent's own production traces into a self-training router: it simulates the tools an agent calls, then learns which model — frontier, open-source, or a distilled specialist — should handle each request at the lowest cost.
Silen Naihin (AutoGPT creator) and Kion Fallah launched it via Show HN on July 26, 2026, claiming up to −66.5% cost versus Claude Fable 5 on RouterBench. Their startup, Experiential Labs, is backed by Y Combinator's Summer 2026 batch and passed 337 GitHub stars within two weeks.
Think of WMO as a thermostat for your AI bill: it keeps routing to cheaper models until quality slips, then dials back up.

Buildable pitches — turn this term into an article, site, product, post, newsletter, video, or course. Steal any card and run with it.
No neutral comparison exists yet. Cover self-training routers (WMO) against static config-based ones (LiteLLM, OpenRouter) on real cost data.
Step-by-step: `wmo build`, `wmo optimize`, `wmo serve` against your own agent traces — a genuine tutorial gap right now.
Explain the free-CLI-now, paid-platform-later split before Experiential Labs publishes its own pricing page.
Teams already standardized on LiteLLM won't rip out infra to try WMO; a compatibility shim removes that switching cost.

The SEO-collision angle: bare 'wmo' means a UN weather body and a fishing tournament to Google.
Visual cost-vs-quality plots are the fastest way to make routing claims legible to a non-ML audience.
While every AI lab ships a bigger flagship model, three ex-AutoGPT engineers are betting the real margin is in routing traffic away from them.
Every vendor pitch this year has been 'buy more frontier tokens.' WMO's pitch is the opposite: stop paying frontier prices for tasks a cheaper model already nails.
Confidence-gated routing sounds great until your router silently downgrades a task you actually needed Opus-quality reasoning for.
