See how this story connects

Source: Anthropic

Anthropic released the Claude 3 family on 4 March 2024: Haiku, Sonnet and Opus, all with a 200,000-token context window. Opus and Sonnet went live in claude.ai and the Claude API, available in 159 countries, with Haiku to follow; API prices ran from $0.25 and $1.25 per million input and output tokens for Haiku to $15 and $75 for Opus. Anthropic said Opus outperformed its peers on most common benchmarks, among them MMLU, GPQA and GSM8K.

Why it matters

Buyers got three price tiers from one provider, with a 60-fold spread in input prices, and a top model that Anthropic said led its peers on common benchmarks.
