Claude 3 was a previous generation of Anthropic's AI models, announced on March 4, 2024. It consisted of three state-of-the-art models at the time: Claude 3 Haiku, Claude 3 Sonnet, and Claude 3 Opus. Claude 3 Opus was the pinnacle of intelligence in the Claude 3 series, outperforming its peers on most common evaluation benchmarks for AI systems, such as undergraduate and graduate-level expert knowledge, mathematics, and more. It exhibited near-human levels of comprehension and fluency on complex tasks. Claude 3 Sonnet struck an ideal balance between intelligence and speed, particularly for enterprise workloads. It delivered strong performance at a lower cost compared to its peers, engineered for high endurance in large-scale AI deployments. Claude 3 Haiku was the fastest and most compact model in the Claude 3 family, designed for near-instant responsiveness. It answered simple queries and requests with unmatched speed at the time. However, Anthropic has since released the next-generation Claude 3.5 series, with the first model Claude 3.5 Sonnet launching on June 21, 2024. Claude 3.5 represents a big advancement over the Claude 3 models in areas like intelligence, reasoning, processing speed, cost-effectiveness, and vision capabilities. Additional models in the 3.5 series, Claude 3.5 Haiku and Claude 3.5 Opus, are expected to be released later in 2024 to round out Anthropic's latest offerings.
