Thinking Machines Releases Inkling 2 Small Weights on HuggingFace Under an Apache 2.0 License

Context

Thinking Machines posted that Inkling 2 Small's weights are now available for download on HuggingFace under an Apache 2.0 license. The post linked to the model page on HuggingFace and invited people to make Inkling their own.

Deep dive

Thinking Machines, the lab led by Mira Murati, posted on November 12 that Inkling 2 Small's weights are now available for download on HuggingFace under an Apache 2.0 license. The post said "Make Inkling your own!" and linked to the official Inkling 2 Small model page on HuggingFace.

The official post does not list parameter counts, benchmarks, training data, or a longer technical card in the text itself. What it does confirm is that the Small weights are public and that the license is Apache 2.0, a standard open source license that allows use, modification, and redistribution, including in commercial products, with attribution. Further details, if any, sit on the linked HuggingFace page rather than in the post.

This is a weights release, not a new hosted demo in the post. Builders can download the checkpoint and run or fine tune it themselves, which is the main practical change from a closed API only release. Until independent tests appear, the quality and intended use of Inkling 2 Small should be judged from those later evaluations, not from the announcement text alone.

What to expect next

Watch whether builders actually download and fine tune the weights, and whether Thinking Machines follows this with more Inkling sizes or a longer official writeup. Independent tests will matter more than the announcement, because the post itself gives little on quality or intended use. A next signal would be a first serious public evaluation, or a follow up release that extends the open weights beyond this Small checkpoint. It is also worth watching whether the Apache 2.0 terms stay attached to later Inkling releases, or whether later versions move to a more restrictive license.
