It’s not just gas prices skyrocketing. Frontier-model pricing keeps climbing too
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). Its predecessor GPT-5.4 charges $2.50 (input), $0.25 (cached input), and $15 (output) per 1 million tokens.
The AI biz claims that the cost increase is offset to some extent by token processing efficiency – delivering better results using fewer tokens.
"While GPT‑5.5 is priced higher than GPT‑5.4, it is both more intelligent and much more token efficient," the company said during the rollout.
But the cost is still going up, more than efficiency improvements are reducing costs. According to an analysisconducted by OpenRouter,...
