Thinking Machines Lab Inc. is an American artificial intelligence (AI) startup founded by Mira Murati, the former chief technology officer of OpenAI.[2] Their flagship model is Inkling, an open weights large language model.

The company was founded in February 2025, and by July had completed an early-stage funding round led by Andreessen Horowitz, raising $2 billion at a valuation of $12 billion overall from investors such as Nvidia, AMD, Cisco, and Jane Street.[3] The company is based in San Francisco and structured as a public benefit corporation.[4][5]

Inkling released under the Apache License on July 15, 2026, with 975 billion parameters; the company released Inkling Small, a distilled 276-billion parameter model with similar performance, the same month. The model was partially developed using Chinese open weights models DeepSeek-V3 for its foundation and Moonshot AI's Kimi K2.5 for post-training synthetic data. At the time, Inkling was considered the largest and most powerful open weights model released outside of China, exceeding Nvidia's Nemotron 3 Ultra.[6][7][8][9]

Thinking Machines launched Tinker, an API for fine-tuning open weights models, in October 2025. As of August 2026, Tinker supports open models families Inkling, Qwen, and Nemotron, and models DeepSeek-V3.1, GLM-5.3, Kimi K2.6, and gpt-oss.[10]

History

[edit]

By its launch in February 2025, Thinking Machines Lab was reported to have hired about 30 researchers and engineers from competitors including OpenAI, Meta AI, and Mistral AI.[11][12][13][14][15] Its founding team members include Barret Zoph, former OpenAI VP of Research (Post-Training), Lilian Weng, former OpenAI VP, and OpenAI cofounder John Schulman, who joined after a brief stint at the lab's competitor Anthropic.[16][17][18]

In January 2026, it was reported that Barret Zoph and Luke Metz, departed the startup to return to OpenAI.[19]

Other former OpenAI employees who have been hired include Jonathan Lachman and Andrew Tulloch (although Tulloch departed after getting recruited for Meta Superintelligence Labs).[20][21] Thinking Machines Lab's advisers include Bob McGrew, previously OpenAI's chief research officer, and Alec Radford, who was a lead researcher for OpenAI.[22][23]

In March 2026, Thinking Machines Lab announced a strategic partnership with NVIDIA involving an undisclosed investment and a multi-year agreement to deploy one gigawatt of Vera Rubin computing capacity.[24][25]

In August 2026, the company moved its headquarters to the office building 2300 Harrison St, in San Francisco's Mission District.[26]

Products

[edit]

On October 1, 2025, Thinking Machines Lab announced Tinker, an API for fine-tuning language models. Users would submit jobs through the API for fine-tuning one of the various open-weight models supported. The Lab would run the jobs on its internal clusters and training infrastructure.[27] As of August 2026, Tinker supports open models families Inkling, Qwen, and Nemotron, and models DeepSeek-V3.1, GLM-5.3, Kimi K2.6, and gpt-oss.[10]

Thinking Machines Lab released its large language model Inkling on July 15, 2026, under the Apache License, with 975 billion parameters.[28] The model drew from Chinese open weights models DeepSeek-V3 for its architecture and Moonshot AI's Kimi K2.5 for post-training synthetic data.[29][30] Media outlets described Inkling the leading non-Chinese open-weights model, ahead of Nvidia's Nemotron, Mistral AI's models and, Google DeepMind's Gemma, but noting a lag behind China's open-weights releases by Z.ai, DeepSeek, MiniMax Group, and Xiaomi MiMo.[6][7][8][9]

Inkling Small, a 276-billion parameter model with comparable performance to Inkling, was released by the company on July 31, 2026.[31]

Business structure

[edit]

Thinking Machines Lab grants Mira Murati a deciding vote on board matters, weighted to provide her with a majority decision-making capability. Additionally, founding shareholders possess votes weighted 100 times greater than those of regular shareholders.[32]

In July 2025, Andreessen Horowitz was reported to have led the company's initial funding round, raising "about $2 billion at a valuation of $12 billion".[3][33][34] The government of Albania (Murati's country of origin) was also included in this round, making a $10 million investment which required an amendment to the country's 2025 budget.[35][36]
