Reax Labs released REAX 1.2 under the Apache-2.0 license as open weights (a fine-tune of REAX 1), with REAX 1.1 also live on Hugging Face.
The author frames these "decision models" as the "math co-processors" of AI: a class of processing that gets offloaded from the main model, reportedly covering around 20-30% of prompts. The Reax subnet provides decision models and inference, powered by Bittensor (TAO).
