About
Thinking Machines Lab was founded by Mira Murati, who served as Chief Technology Officer of OpenAI before departing in 2024. Murati's tenure at OpenAI oversaw the development and launch of GPT-4, DALL-E, and ChatGPT, giving her unmatched firsthand experience with the technical and organizational challenges of frontier AI development. She founded Thinking Machines Lab with the mission of building AI systems that are both highly capable and deeply aligned with human values and intent.\n\nThinking Machines Lab operates as an AI research organization focused on developing next-generation foundation models and the scientific frameworks needed to make powerful AI systems more reliable, interpretable, and beneficial. The company has assembled a team of researchers from leading AI institutions and is building the compute infrastructure necessary for frontier model training. It secured a multi-year compute agreement with NVIDIA, ensuring access to the GPU capacity required to compete at the frontier of AI research.\n\nThe company raised $2 billion at a $12 billion valuation, with participation from Andreessen Horowitz, NVIDIA, and AMD — a capital raise that ranks among the largest first rounds in technology history. The involvement of both major AI chip vendors as strategic investors signals deep alignment between Thinking Machines Lab's compute roadmap and the hardware ecosystem. With Murati's profile, the caliber of its investor base, and its frontier research mandate, Thinking Machines Lab is positioned as one of the most closely watched AI labs in the post-ChatGPT era.
ChatGPT surpassed 400M weekly active users in February 2025 and launched GPT-4o with voice, image, and real-time reasoning — the world's most-used AI product.
