Why run WorkDaddy agents on OpenCode Zen in 2026
Tool calling, context size, and cost decide how well a provider drives an agent team. OpenCode Zen brings 85 tool-calling models to WorkDaddy — enough to power the full loop of storefront edits, analytics queries, and content production — with 1.1M tokens of context at the top end for whole-codebase and long-report work. Because WorkDaddy is model-agnostic, you can route heavy reasoning to OpenCode Zen’s strongest model and bulk work to its cheapest, inside one team.
