Cursor with your own key
Cursor lets you supply an Anthropic or OpenAI key instead of using their pooled quota. When you do, you pay raw token cost — which means the per-token rate is the only thing that matters. See the Cursor setup guide.
Figures are estimates based on list prices verified 2026-09-16. Actual spend depends on your cache hit rate, batch usage and long-context tiering.
