OpenAI's GPT-5.5 model offers improved efficiency, yet actual operational costs for users have increased significantly compared to its predecessor.Summary
OpenAI has introduced GPT-5.5, which features higher per-token pricing despite claims of improved token efficiency. While the company suggests that better results using fewer tokens should offset the costs, analysis by OpenRouter reveals that actual user expenses have risen between 49 percent and 92 percent. This trend of rising costs to sustain AI development is also impacting competitors like Anthropic, whose latest models have similarly led to increased expenses for longer prompts.
