The table on https://developers.openai.com/api/docs/pricing is more readable:
+--------------+-------+--------------+--------------+--------+
| Model | Input | Cached input | Cache writes | Output |
+--------------+-------+--------------+--------------+--------+
| gpt-6-luna | $0.10 | $0.01 | $0.125 | $0.50 |
| gpt-5.6-luna | $0.20 | $0.02 | $0.25 | $1.20 |
+--------------+-------+--------------+--------------+--------+
Yeah, how they put, is confusing to me, they should have put that table instead of what they have right now in the article.
