I would investigate if the $20/month plan is good enough for your use: The token-based plans usually work out to be much more expensive than the monthly ones. Or get both the Anthropic and Codex $20/month plans. I don't know if this makes sense compared to your current use case, but there is a very good chance it does given how much the per-token plans cost. The primary use case for them is enterprises that aren't allowed to use the monthly subscriptions.
