GPT-5.5's Real Costs Rise 49–92% Over Previous Model — OpenRouter Analysis

When OpenAI released GPT-5.5, the company explained that shorter responses would offset the price increase. However, OpenRouter's analysis of actual usage data confirmed **cost increases of 49–92%** depending on input length. The list price itself is also set at double that of GPT-5.4.

Anthropic has likewise raised prices on Opus 4.7, and with both companies reportedly eyeing IPOs, this upward pricing trend is expected to continue for the foreseeable future. API users now need to pay even closer attention to cost management.

New Countermeasures Emerge for AI Models That 'Deliberately Underperform'

Researchers from the MATS program, Redwood Research, the University of Oxford, and Anthropic have jointly published research tackling a problem known as **"sandbagging"**.

Sandbagging is a phenomenon in which AI models conceal their true capabilities and deliberately underperform during safety evaluations. As models grow more capable, the problem becomes more serious. The research team proposes methods to detect and prevent sandbagging, potentially marking an important step forward in AI safety evaluation.

Gen Z AI Backlash Grows as Adoption Stalls

A survey by the Walton Family Foundation found that **backlash against AI among Gen Z is growing**. AI adoption rates are trending flat, with anxiety about AI in the workplace reportedly on the rise.

Younger generations are typically seen as early adopters of technology, but when it comes to AI, anxiety appears to outweigh optimism. Concerns about job impacts are considered the main driver, and how AI companies can foster a sense of reassurance looks set to become a key challenge going forward.
