About Moonshot AI
Moonshot AI is a Beijing-based artificial intelligence company founded in March 2023 by Tsinghua University alumni Yang Zhilin, Zhou Xinyu, and Wu Yuxin. The company's name was inspired by Pink Floyd's The Dark Side of the Moon. Moonshot developed Kimi, a chatbot capable of processing up to 2 million Chinese characters per conversation, demonstrating advanced long-context capabilities. The company achieved rapid growth, raising USD 1 billion from Alibaba at a USD 2.5 billion valuation in February 2024, followed by USD 300 million from Tencent and Gaorong Capital at a USD 3.3 billion valuation in August 2024. Kimi K2 delivers competitive performance with fresh, non-sycophantic communication praised by former OpenAI researchers, with API pricing at USD 0.15-2.50 per million tokens undercutting Western competitors. However, infrastructure reliability issues caused frequent outages during peak usage, and Anthropic accused Moonshot of using fraudulent accounts to scrape Claude conversations for training in February 2026.
About OpenAI
OpenAI is the creator of ChatGPT and the GPT series of large language models, having pioneered the commercial LLM API market. Founded in December 2015 by Sam Altman, Elon Musk, Greg Brockman, Ilya Sutskever, and others as a non-profit, it transitioned to a capped-profit model in 2019 and is currently restructuring as a for-profit public benefit corporation.
OpenAI's API platform provides access to text generation (GPT-4o, GPT-5, o-series reasoning models), image generation (DALL-E), speech-to-text (Whisper), text-to-speech, and embedding models. The platform supports fine-tuning, function calling, and the Responses API for agent-native workflows. The open-source Agents SDK and tools like code interpreter and web search enable developers to build sophisticated AI applications.
In February 2026, OpenAI closed a record $110 billion funding round from Amazon, Nvidia, and SoftBank, valuing the company at $840 billion post-money. The company employs approximately 3,500-7,200 people and is reportedly targeting a 2027 IPO at up to a $1 trillion valuation.
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.
