Kev 9B v1.0 — packed GGUF

Kev-9B is a Jev-style "System One" decision model: a Qwen3.5-9B backbone plus a trained pointer head that returns calibrated probabilities for typed questions instead of generating text.

Built from Kev v1.0 — jaredpalmer/kev-9b @ db029f0 (LoRA adapter + head.pt) merged onto Qwen/Qwen3.5-9B-Base @ 68c46c4b with espetro/llama.cpp's tools/kev pipeline (kev_v10_merge.py -> convert_hf_to_gguf --no-mtp -> kev_head.py -> kev_pack.py). The pointer head and calibration temperature (2.1936) are baked in as dec.head_* tensors + kev.* metadata.

The files still load in stock llama.cpp as an ordinary Qwen3.5 model — the kev.* metadata and head tensors are simply ignored there.

espetro.github.io/llama.cpp runs the 0.8B demo quant in llama.cpp WASM. For a smaller local download of this model, see espetro/kev-9b-demo-gguf.
