Inkling: Thinking Machines Lab's first open-weights model

2026-07-17 ยท source:

Inkling is Thinking Machines Lab's Apache-2.0 licensed Mixture-of-Experts model with 975B total and 41B active parameters, trained on 45 trillion multimodal tokens.

What it is

An open-weights multimodal Mixture-of-Experts transformer model released by Mira Murati's Thinking Machines Lab.

What it does

It processes text, images, audio, and video after training on 45 trillion tokens, and is released under an Apache-2.0 license alongside a promised smaller Inkling-Small variant of 276B total and 12B active parameters.

Why it matters

An Apache-2.0 licensed model of this scale from a new lab gives engineers another self-hostable alternative to closed frontier APIs for multimodal workloads, competing with DeepSeek V4 Pro and Kimi K3.

How to use it

Download the weights from Thinking Machines Lab once published and serve them with a compatible inference stack; Inkling-Small is not yet available pending further testing.
