This repository contains all three dense reasoning models from IBM's Granite 4.2 family: 3B, 8B and 30B, each converted directly from the original bf16 checkpoint to Q4TP and Q8_2F CMF. A CMF is one memory-mapped file containing the weights, tokenizer, exact chat template and integrity hashes. The same artifact runs on CPU, Vulkan (NVIDIA/AMD/Intel), DX12 and Metal; inference needs no Python, PyTorch, CUDA toolkit or model-specific GPU build. Use `--no-think` for a direct answer. Without it, the embedded Granite template opens the model's native ` ... ` reasoning block. Numbers are single-stream `cortiq bench --tokens 100 --core --ignore-eos` steady decode on an NVIDIA A40. They exclude model load and prompt prefill. The 3B Q4TP run prefills at 80.3 tok/s and reaches first token in 0.58 s; its Q8_2F control prefills at 47.5 tok/s and reaches first token in 0.93 s. The 30B Q8_2F file is larger than the A40's safe physical graph live set: Cortiq automatically kept 55 of 64 layers on Vulkan and ran the nine-layer tail on the host. That 100-token run peaked at 43,036 MiB of the A40's 46,068 MiB and completed without steady-state weight uploads.
