Granite 4.2 8B is a dense model with 8B parameters. IBM lists a context window of 128K tokens natively, with a long-context extension to 512K. The model takes text input. The weights are released under Apache 2.0, which allows commercial use. The official weights on Hugging Face take about 17.6 GB in BF16. Running the model needs at least that much memory across GPUs and system RAM, plus room for the context cache; quantized versions need less.
