OpenAI has released GPT-5.5, which reportedly excels not in benchmark scores but in practical reliability for complex tasks. The new model demonstrates significantly improved instruction following, reduced hallucination rates, and native agentic behavior that maintains coherence across multi-step operations. This focus on reliability at scale could allow developers to simplify their AI agent architectures by removing layers of scaffolding previously needed to compensate for model inconsistencies. AI
