The Claude 3 family arrives: Opus, Sonnet, Haiku
Anthropic introduced the three-model Claude 3 family: Opus at the top, Sonnet balancing capability and speed, and Haiku as the fastest and most compact — a pick-by-need lineup that split one generation into three tiers by capability and speed, released together. Anthropic said Opus outperformed rivals on most common benchmarks including MMLU, GPQA, and GSM8K, the first generation it claimed beat GPT-4. All three models handled image input, reading photos, charts, graphs, and technical diagrams. Opus and Sonnet shipped at announcement on the API and claude.ai, with the API generally available in 159 countries; Haiku followed later.
