Claude 3 Opus

by Anthropic

AI Model
Low Confidence

Claude 3 Opus is the most powerful model in the Claude 3 family, released by Anthropic in March 2024. It excels in complex reasoning, advanced coding, nuanced understanding, and multimodal tasks (e.g., analyzing images, documents, and charts). The model is optimized for high-stakes, high-impact applications and demonstrates state-of-the-art performance on benchmarks like MMLU, GPQA, and human preference evaluations. Claude 3 Opus was trained on a proprietary mix of publicly available internet data (up to August 2023), private datasets, and internally generated data. It underwent RLHF (Reinforcement Learning from Human Feedback) and Constitutional AI fine-tuning to align with principles like helpfulness, honesty, and harmlessness. The model is multimodal (text and vision) and multilingual. Safety evaluations show strong alignment, with low rates of harmful outputs and high resistance to jailbreaks. It was deployed under AI Safety Level 2 (ASL-2) protections.
