Anthropic launches the Claude 3 model family

Anthropic released Claude 3 Opus, Sonnet, and Haiku on 4 March 2024, three models spanning a range of speed and capability, with a 200,000-token context window and image input. Anthropic reported that Opus matched or exceeded GPT-4 on several public benchmarks.

Why it mattered Claude 3 Opus was the first model widely judged competitive with or ahead of GPT-4, ending OpenAI’s run as the undisputed leader in general-purpose language models.
