GPT-5.5 prices rise up to 92% post-upgrade
openai's price hike for gpt-5.5 results in a 49 to 92 percent cost increase for most tasks, with some overhead partially offset by shorter outputs.
openai increased gpt-5.5 list prices to $5 for input and $30 for output tokens. openrouter analysis shows real-world costs rose 49 to 92 percent despite shorter responses for longer inputs. shorter queries under 2,000 tokens see negligible efficiency gains, nearly doubling costs.
