alt Hacker Newsthey tested it at xhigh reasoning though, which is probably double the cost of Anthropic's model.
Cost to Run Artificial Analysis Intelligence Index:
GPT-5.2 Codex (xhigh): $3244
Claude Opus 4.5-reasoning: $1485
(and probably similar values for the newer models?)

A provider's API costs seemingly do not reflect each respective SOTA provider's subscription usage allowances.
With $20 gpt plan you can use xhigh no problem. With $20 Claude plan you reach the 5h limit with a single feature.
