OpenAI released GPT-5.5 on April 23 as its most advanced agentic AI model to date. The company built this model specifically for autonomous task completion, enabling it to plan independently, use tools, verify its own outputs, and work through complex problems without constant human intervention. OpenAI frames GPT-5.5 as a new class of intelligence designed for real-world work and agent applications, signaling a shift toward AI systems that operate with greater autonomy. The model represents a step forward in agentic AI capabilities, distinguishing itself from previous versions through architectural improvements focused on agent functionality. However, the company charges twice the API price of earlier models, reflecting the increased computational resources and capabilities the system demands. This pricing strategy indicates OpenAI's positioning of GPT-5.5 as an enterprise-grade tool rather than a general-purpose model. The launch targets developers and businesses seeking AI agents capable of handling multi-step workflows and real-world applications with minimal human oversight.
