# Qwen 3.8 27B for the modding agent.
# Needs Ollama 0.32.12 or newer (older versions fail the pull with "requires a newer version of Ollama").
#   Check:  ollama --version      Update Ollama if older.
# Build:  ollama create modding-qwen38 -f Modelfile.qwen38
# Run:    python modding_agent.py --preset qwen38 --allow "C:/Games"
#
# qwen3.8:27b on the Ollama library: dense 27B, Q4_K_M, about 18 GB (weights plus a vision projector),
# ~256K native context, tags: vision, tools, thinking. Other tag mentioned by the library: qwen3.8:27b-q8_0 (~30 GB).
# On a 16 GB GPU it will not fit fully in VRAM: Ollama splits it between GPU and system RAM (check with `ollama ps`).
# It is a dense model (all parameters used per token), so a split is slower than it would be for a mixture-of-experts.
# Verify first:  ollama show qwen3.8:27b   (look for "tools" and "thinking")
FROM qwen3.8:27b

# Your own GGUF instead? It needs a ChatML + tools template: copy TEMPLATE and the stop parameters from
#   ollama show --modelfile qwen3.8:27b     then use   FROM ./your-qwen3.8.gguf

PARAMETER num_ctx 8192
# Qwen3-family sampling advice for thinking-style models (confirm on the model card for your exact release)
PARAMETER temperature 0.6
PARAMETER top_p 0.95
PARAMETER top_k 20

# Thinking is ON by default and can run away (one test saw a 50,000-character thinking trace). For tool loops the agent
# sends think=false (--think off, set by --preset qwen38). Ollama has no Modelfile setting for this; it is an API option.
