Résumé

In a landmark AI release day, Anthropic and OpenAI simultaneously launched two cutting-edge AI models: Claude Opus 4.6 and GPT 5.3 Codex. Anthropic's Claude Opus 4.6 introduces a revolutionary million-token context window, exceptional coding capabilities, and superior performance across multiple benchmarks. It outperforms previous models by significant margins, achieving the highest score on Terminal Bench 2.0 and demonstrating remarkable context retrieval abilities. OpenAI's GPT 5.3 Codex countered with a model that not only writes and reviews code but aims to function as a comprehensive digital coworker capable of handling entire software development cycles. The model notably created two complete browser games autonomously and claims 25% faster performance compared to previous versions. Both companies emphasized the models' advanced reasoning, coding prowess, and ability to handle complex professional tasks. The release represents a significant leap in AI capabilities, with both models showcasing unprecedented autonomous development and task completion skills. The competition between these tech giants is driving rapid innovation, benefiting developers and professionals across multiple domains.
