# Pacific Slate > Personal AI platform built and operated by Ryan Thompson: a self-hosted multi-agent system with its own memory, tool layer, cost governance, and fallback design. This site is the architecture writeup plus a static demo. It is a personal build at personal scale, not a product. ## Content - [Page as Markdown](https://raw.githubusercontent.com/pacific-slate/pacslate/main/README.md): the full writeup, single source for the site. - [Fallback pattern](https://raw.githubusercontent.com/pacific-slate/pacslate/main/examples/model_fallback.py): the resilient-call pattern, simplified, reasoning in comments. - [Routing and budget config](https://raw.githubusercontent.com/pacific-slate/pacslate/main/examples/model-routing.example.yaml): the real config structure with illustrative model IDs. ## Optional - [Live demo](https://pacslate.com/demo): the real interface on sample data, no backend. - Model names on the page are illustrative; the design is model-agnostic. Counts were checked against the running system in August 2026.
