GPT-5.5 may burn fewer tokens, but it always burns more cash

It's getting more expensive to use the latest models. OpenAI last month bumped the version number of its GPT model family to 5.5, and per-token prices rose too, in some cases doubling compared to its predecessor. For 1 million tokens, GPT-5.5 is priced at $5 (input), $0.50 (cached input), and $30 (output).
