Granite 4.0 H 350M

A Core AI bundle of ibm-granite/granite-4.0-h-350m for the Aether SDK (iOS and macOS 27+).

• Source: ibm-granite/granite-4.0-h-350m at revision 3b17b717b8f2f5d305b0a92c1491e239aeda19c8, licence Apache-2.0. The licence is included as LICENSE. ibm-granite/granite-4.0-h-350m declares apache-2.0 in its model card but ships no licence file; LICENSE is the canonical text from apache.org.
• Changes from the source: converted from PyTorch to Core AI (.aimodel) by Aether forge (recipe granite-4.0-h-350m@5). Weights are float16 (16-bit weights). The tokenizer files are the source's own.
