OpenAI released GPT-5.5 on April 23, 2026, positioning it as a "new class of intelligence" optimized for agentic workflows—autonomous multi-step tasks like coding, web browsing, data analysis, and complex problem-solving.

The model rolled out quickly to ChatGPT Plus, Pro, Business, and Enterprise users, with API access following shortly. However, the pricing sparked immediate debate: standard GPT-5.5 costs $5 per 1M input tokens and $30 per 1M output tokens —exactly double the rates of GPT-5.4 ($2.50/$15). The Pro variant jumps to $30/$180.

Is this premium justified by superior performance, or should users stick with previous versions or alternatives?
