Anthropic has launched its latest AI models, Claude Opus 4 and Claude Sonnet 4, showcasing significant advancements in autonomous coding and reasoning capabilities. Claude Opus 4 demonstrated the ability to code independently for nearly seven hours during testing, a substantial improvement over previous iterations. To address potential misuse, particularly in sensitive areas like bioweapons development, Anthropic implemented its AI Safety Level 3 (ASL-3) protocols, incorporating enhanced cybersecurity and prompt classifiers. Both models introduce features such as “thinking summaries” and an “extended thinking” mode, aiming to provide clearer reasoning insights and improved performance. This release positions Anthropic as a formidable competitor in the AI landscape, challenging offerings from OpenAI and Google.
