OpenAI's GPT-5.5 surpasses rivals in AI benchmarks

OpenAI has unveiled GPT-5.5, its newest AI model, which has retaken the lead in generally available large language models, outperforming competitors like Anthropic's Claude Opus 4.7 and Google's Gemini 3.1 Pro on numerous benchmarks. The model shows significant improvements in coding, computer use, and scientific research, with a focus on 'agentic' performance allowing it to handle complex tasks autonomously. Despite a notable price increase for API access, GPT-5.5's enhanced efficiency and capabilities are generating strong positive reactions from developers and researchers.
