I’m confused why a business would allow (non-data-science/agent harness devs) to pay per token instead of eg an Anthropic business premium seat? A monthly subscription seems pretty straight forward for the accountants, no?
At this point the subsidized rates are only available with individual plans. In principle your workplace can pay for an individual plan for you, but for compliance reasons that is likely only feasible at smaller places that are primarily open source oriented (so there's little risk of proprietary code leaking).
