I can read it as follows (below), meaning that GPT-5.6 is 50% cheaper.

- GPT-6 = $0.20

- GPT-5.6 = $0.10

The table on https://developers.openai.com/api/docs/pricing is more readable:

  +--------------+-------+--------------+--------------+--------+

  +--------------+-------+--------------+--------------+--------+
  | gpt-6-luna   | $0.10 | $0.01        | $0.125       | $0.50  |
  | gpt-5.6-luna | $0.20 | $0.02        | $0.25        | $1.20  |

Yes, GPT-6 Luna is 50%-58% cheaper than GPT-5.6 Luna. (I think the blog text and graphs make it pretty clear.)
