The upstream model card declares Apache-2.0 and ships no LICENSE file;

Original model and tokenizer: Allen Institute for Artificial Intelligence
and the upstream contributors. Converted to Core AI float16 weights and
cache storage, with explicit float32 attention arithmetic, using AetherKit.
The tokenizer files are unchanged from the source checkpoint.

AetherKit export tooling follows the OLMo2 forward pass in Hugging Face
Transformers 4.57.3, licensed under Apache-2.0. AetherKit is Apache-2.0.
