Thinking Machines Open-Sources Inkling 2 Small: 594B MoE under Apache 2.0
Thinking Machines founder Miriam Murati announced the release of the Inkling 2 Small model weights as promised. The model is now available on Hugging Face under an Apache 2.0 license, allowing the community to fine-tune and use it commercially. This fulfills the team's commitment to open weights for its small model—a notable example of a top startup releasing a large-parameter model under a permissive license.
Confirmed
- The model is Inkling 2 Small, with weights available on Hugging Face under Apache 2.0 (announced by @miramurati and @thinkymachines)
- Architecture is MoE, with 594B total parameters and 17B active parameters (@ariG23498 citing the official HF article)
- Supports adjustable reasoning via a custom chat template
- HF updated its official model article accordingly; HF engineers including ariG23498 reshared the announcement
- In her announcement, Murati thanked the team and safety-testing partners; members such as Andrew Carr congratulated the release
Why it matters
- Apache 2.0 is among the most permissive open-source licenses, allowing commercial use and free fine-tuning, which helps grow the community ecosystem
- Releasing a 594B-parameter MoE with open weights makes it one of the larger-scale open models, with real reference and practical value for the open-source community
