Methodology for operating Fable, Kimi K3, Grok, and Codex as one fleet — contracts, discovery, quiet Model tabs.
TL;DR: Separate host × brain × via. Discover installs. Show only used hosts. Measure capacity not hype.
Five rules
- Separate host, brain, via
- Quiet default UI (Claude always; others on discover; Mixtures/All pin)
- One list contract for every host
- Capacity first-class
- Prove with sessions + discovery tests
Anti-patterns
Hard-coded three Model tabs forever · Showing locked hosts for marketing · Per-model UI forks · Claiming any-model support without contracts.
