Thinking Machines Lab Launches Its First Model, an Open-Weight System Called Inkling

Thinking Machines Lab, the startup founded by former OpenAI chief technology officer Mira Murati, released its first in-house AI model on July 15, 2026, an open-weight multimodal system named Inkling that ships under the permissive Apache 2.0 license. The company published the full model weights on Hugging Face and made the model immediately available for customization through its Tinker fine-tuning platform, positioning Inkling not as a bid for the single strongest model on the market but as a highly customizable foundation that developers can download, modify and adapt to their own needs.
