While OpenAI’s monthly subscription prices remain the same, the company says it’s also adjusting token usage for Terra and Luna models today as well. “These lower prices for Luna and Terra are also reflected in how usage is counted against paid subscriptions when using Codex and ChatGPT Work,” OpenAI says.
