Anthropic is an AI safety and research company that builds the Claude family of large language models. Founded in 2021 by Dario Amodei (CEO) and Daniela Amodei (President), along with five other former OpenAI employees, the company is structured as a Public Benefit Corporation with a Long-Term Benefit Trust to prioritize societal benefit.
Claude models are known for strong reasoning capabilities, large context windows (up to 200K tokens), and an emphasis on safety and reliability. Claude Sonnet 4.5 leads as the top coding model with 77.2% on SWE-bench Verified, while the three-tier pricing system (Haiku, Sonnet, Opus) provides flexibility for different use cases. Anthropic pioneered Constitutional AI and created the Model Context Protocol (MCP), now an industry standard for AI tool integration donated to the Linux Foundation.
The company serves enterprise customers through both its API platform and the Claude.ai consumer product. Claude has grown from 2.9 million monthly users in January 2024 to 18.9 million by early 2025, with $850 million in annualized revenue. As of February 2026, Anthropic is valued at approximately $380 billion and employs roughly 2,000-4,000 people across its San Francisco headquarters.
DeepSeek is a Chinese artificial intelligence company founded in July 2023 by Liang Wenfeng, co-founder of the hedge fund High-Flyer, which owns and funds the company. Headquartered in Hangzhou, Zhejiang, DeepSeek focuses on developing open-source large language models (LLMs) that have sent shock waves through the global AI industry. The company gained international attention with its R1 model release, demonstrating advanced AI reasoning capabilities at a fraction of the cost of competing American models.
DeepSeek's breakthrough technology has been described as triggering a 'Sputnik moment' for the United States in artificial intelligence, particularly due to its cost-effective, high-performing, and open-source approach. The company's models challenge the prevailing narrative that building cutting-edge AI requires massive capital expenditure, proving that innovative architecture and optimization can achieve comparable results more efficiently. This achievement has significant implications for the democratization of AI technology globally.
The company's commitment to open-source development sets it apart from many competitors, allowing researchers and developers worldwide to access, study, and build upon DeepSeek's innovations. DeepSeek's success demonstrates China's growing capabilities in AI research and development, particularly in creating efficient models that can compete with well-funded Western counterparts. The company continues to advance the state of the art in LLM development while maintaining its focus on accessibility and cost-effectiveness.
Companies that train and release their own large language models and foundation models. These organizations invest in large-scale model training, publish research, and offer API access to their proprietary models.
