From 895d6c6ba33497707e1cb9f6cf58ac4da83dd6f0 Mon Sep 17 00:00:00 2001 From: Alexander Whitestone Date: Mon, 23 Mar 2026 13:58:40 -0400 Subject: [PATCH] feat: add Hermes 4 14B Modelfile, providers config, and smoke test suite Sets up the AutoLoRA base model infrastructure for Project Bannerlord. No live model download (requires manual GGUF import into Ollama), but provides all scaffolding needed to onboard and validate the model. Changes: - Modelfile.hermes4-14b: Ollama Modelfile for NousResearch Hermes 4 14B (Q5_K_M, 32K context, temp=0.3, tool-calling + reasoning configured) - config/providers.yaml: register hermes4-14b and hermes4-36b as model entries on ollama-local; hermes4-14b promoted to top of tools fallback chain (native tool calling + structured JSON) - scripts/test_hermes4.py: 5-test smoke suite (availability, basic response, memory < 28 GB, tool calling, Timmy-persona acceptance) Refs #1101 --- Modelfile.hermes4-14b | 55 +++++++ config/providers.yaml | 19 ++- scripts/test_hermes4.py | 342 ++++++++++++++++++++++++++++++++++++++++ 3 files changed, 415 insertions(+), 1 deletion(-) create mode 100644 Modelfile.hermes4-14b create mode 100644 scripts/test_hermes4.py diff --git a/Modelfile.hermes4-14b b/Modelfile.hermes4-14b new file mode 100644 index 00000000..af78c6fa --- /dev/null +++ b/Modelfile.hermes4-14b @@ -0,0 +1,55 @@ +# Modelfile.hermes4-14b +# +# NousResearch Hermes 4 14B — AutoLoRA base model (Project Bannerlord, Step 2) +# +# Features: native tool calling, hybrid reasoning ( tags), structured +# JSON output, neutral alignment.
