+# NousResearch Hermes 4 14B — AutoLoRA base model (Project Bannerlord, Step 2)
+#
+# Features: native tool calling, hybrid reasoning (<think> tags), structured
+# JSON output, neutral alignment. Built to serve as the LoRA fine-tuning base.
+#
+# Build:
+#   # Download GGUF from HuggingFace first:
+#   #   https://huggingface.co/collections/NousResearch/hermes-4-collection-68a7
+#   #   Pick: NousResearch-Hermes-4-14B-Q5_K_M.gguf (or Q4_K_M for less RAM)
+#   ollama create hermes4-14b -f Modelfile.hermes4-14b
+#
+# Or if hermes4 lands on Ollama registry directly:
+#   ollama pull hermes4:14b
+#   ollama create hermes4-14b -f Modelfile.hermes4-14b
+#
+# Memory budget: ~9 GB at Q4_K_M, ~11 GB at Q5_K_M — leaves headroom on 36 GB M3 Max
+# Context:       32K comfortable (128K theoretical)
+# Primary use:   AutoLoRA base before fine-tuning on Timmy skill set
+
+# --- Option A: import local GGUF (uncomment and set correct path) ---
+# FROM /path/to/NousResearch-Hermes-4-14B-Q5_K_M.gguf
+
+# --- Option B: build from Ollama registry model (if available) ---
+FROM hermes4:14b
+
+# Context window — 32K leaves ~20 GB headroom for KV cache on M3 Max
+PARAMETER num_ctx 32768
+
+# Tool-calling temperature — lower for reliable structured output
+PARAMETER temperature 0.3
+
+# Nucleus sampling — balanced for reasoning + tool use
+PARAMETER top_p 0.9
+
+# Repeat penalty — prevents looping in structured output
+PARAMETER repeat_penalty 1.05
+
+# Stop tokens for Hermes 4 chat template (ChatML format)
+# These are handled automatically by the model's tokenizer config,
+# but listed here for reference.

+SYSTEM """You are Hermes, a helpful, honest, and harmless AI assistant.
+
+You have access to tool calling. When you need to use a tool, output a JSON function call in the following format:
+<tool_call>
+{"name": "function_name", "arguments": {"param": "value"}}
+</tool_call>
+
+You support hybrid reasoning. When asked to think through a problem step-by-step, wrap your reasoning in <think> tags before giving your final answer.
+
+Always provide structured, accurate responses."""

+"""Hermes 4 smoke test and tool-calling validation script.
+
+Tests the Hermes 4 14B model after importing into Ollama. Covers:
+  1. Basic connectivity — model responds
+  2. Memory usage — under 28 GB with model loaded
+  3. Tool calling — structured JSON output (not raw text)
+  4. Reasoning — <think> tag toggling works
+  5. Timmy-persona smoke test — agent identity prompt
+
+Usage:
+    python scripts/test_hermes4.py                    # Run all tests
+    python scripts/test_hermes4.py --model hermes4-14b
