Anthropic

Anthropic, founded by ex-OpenAI researchers Dario and Daniela Amodei, raised $4 billion from Amazon and $2 billion from Google to reach a $60 billion valuation by late 2024. Its Claude 3.5 Sonnet model achieved 92% on the HumanEval coding benchmark, outperforming #1 OpenAI's GPT-4 Turbo by 12 percentage points. This 15% advantage over the average coding benchmark score makes Anthropic the top enterprise AI choice for many Fortune 500 firms, even though its valuation is less than half of OpenAI's.
