What Happened
Anthropic released the Claude 3 model family, consisting of three models spanning a range of capability and cost: Haiku (fastest, most affordable), Sonnet (balanced), and Opus (most capable). All three models supported vision (image understanding) alongside text. Claude 3 Opus matched or exceeded GPT-4 on multiple benchmarks while emphasizing safety and helpfulness.
Why It Matters
Claude 3 established Anthropic as a top-tier competitor in the frontier model race. Opus demonstrated state-of-the-art performance on reasoning, coding, math, and multilingual tasks while maintaining Anthropic's emphasis on safety through Constitutional AI. The three-tier model lineup gave users flexibility to choose the right balance of capability, speed, and cost for different applications, a pattern that became industry standard.
