Pricing

Join the currently open Codex Desktop API launch cohort.

The $3 Founder 100 tier opens first. The $5 and $7 cohorts unlock later only after the earlier paid-subscriber caps are reached.

Sequential launch pricing

The earlier you subscribe, the lower your lifetime monthly basis.

Founder 100 is the only cohort open right now. New subscriber pricing steps up only after each launch cohort fills.

Open now at $3/month
