In the news
Thinking Machines Lab releases Inkling-Small, a smaller open-weight Inkling model
On July 30, 2026 Thinking Machines Lab released Inkling-Small, which it describes as a mixture-of-experts transformer with 276B total and 12B active parameters, trained on NVIDIA GB300 NVL72 systems. The announcement says that, like Inkling, it reasons natively over audio and images, offers variable thinking effort, and supports a context window of up to 1M tokens, and that an earlier checkpoint was post-trained partly through on-policy distillation with Inkling as the teacher. The company says it is releasing the full weights and offering the model for fine-tuning on Tinker; the Hugging Face listing is ungated and licensed under Apache 2.0. USASI has not tested Inkling-Small.
Thinking Machines Lab releases Inkling, its first open-weight model, under Apache 2.0
On July 15, 2026 Thinking Machines Lab released Inkling, a model it says it trained from scratch and published with full weights. The announcement describes a mixture-of-experts transformer with 975B total and 41B active parameters, a context window of up to 1M tokens, and native reasoning over text, images, and audio, and calls it the first in a family of models of different sizes. The weights are published on Hugging Face without gating under the Apache 2.0 license, and the model is also available for fine-tuning on the company's Tinker platform. The announcement says some reported results came from a different checkpoint than the one released. USASI has not tested Inkling.
