GPT-5.5 (Azure) down on OpenRouter (openrouter.ai)

OpenAI has announced the release of GPT-5.5, its latest frontier model now available on Azure and OpenRouter. This model enhances capabilities from the previous version, GPT-5.4, featuring advanced reasoning, improved reliability, and greater token efficiency, particularly for complex professional tasks. Notably, GPT-5.5 supports a massive 1 million token context window, allowing for 922,000 input tokens and 128,000 output tokens, as well as the handling of both text and image inputs to facilitate extensive reasoning, coding, and multimodal workflows. This development is significant for the AI/ML community as it represents a leap towards more comprehensive AI solutions that can manage complex scenarios and integrate various modalities in a single framework. With a pricing structure of $5 per million tokens for inputs and $30 for outputs, GPT-5.5 enables developers and businesses to leverage cutting-edge capabilities while considering operational costs. The release also contributes to the ongoing evolution of AI models, pushing the boundaries of what is possible in machine learning and natural language processing.
