About Anthropic
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.
About Meta AI
Meta AI develops the Llama series of open-weight large language models, which have become the foundation for a large portion of the open-source AI ecosystem. The AI division, formerly known as Facebook AI Research (FAIR), was founded in 2013 by Mark Zuckerberg and Yann LeCun.
Llama models are freely available under a community license for commercial use, can be fine-tuned and self-hosted, and are offered through dozens of inference providers including Together AI, Groq, DeepInfra, and AWS Bedrock. The Llama 4 family includes Scout (109B MoE, 10M context) and Maverick (400B MoE), with competitive performance at a fraction of proprietary model costs.
Meta Platforms employs approximately 78,865 people globally and generated $200.97 billion in revenue in 2025. The company has committed over $60B to AI infrastructure investment and released PyTorch, one of the most widely used machine learning frameworks in the world.
What is Foundation Models?
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.
