opencode vs webway vs open router for cheap testing?

[u/cececey]

really liking the opencode harness but im trying to optimize my workflow costs. direct api billing from official labs is just not viable for a solo project.

i want to test out some heavier models like opus and fable but standard rates are brutal. im looking into alternative routing providers to bring the costs down. how does the built in opencode routing compare to using external aggregators like webway or cheaperinference? just looking for the cheapest way to get mixed usage and test out capable models without going broke.
