Former OpenAI CTO does what Altman won't: releases a frontier AI model that's actually open

Thinking Machines' first open weights model is a 975 billion parameter alternative to Chinese LLMs
If you’re in the market for a frontier-class open weights model, your options are few and far between outside of the Chinese model houses.
With the Wednesday release of a new model code-named "Inkling", an outfit called Thinking Machines Lab aims to change that.
Founded in early 2025 by former OpenAI CTO Mira Murati, Thinking Machines' first model is a big one. Weighing in at 975 billion parameters, the model requires more than two terabytes of GPU memory — a quantity present in around eight of Nvidia's B300 accelerators, or sixteen H200s — to run at its native 16-bit precision. If that’s asking too much of your hardware, Thinking Machines has also released a NVFP4 quantized version of the model capable of running on half the GPUs.
This makes it the largest...
