From the Hugging Face model README
neo-3
This is the 1B-A90M-Base model. Check out the 3B-A400M-Base model and the post-trained version of your model.
The neo-3-1B-A90M and 3B-A400M models are the successor to neo-2-345M-C1 and C2, featuring:
- Pre-trained and post-trained models
- Context windows of 8K for 1B and 32K for 3B
- The first ever neo reasoning model
- Mixtral architecture
The post-trained models will release January 3rd, 2026. The pre-trained models have released on December 31st, 2025. A technical report is on the works, but training data is fully available for replication.
This model has an MIT license.
