Defined in:

Overview

Brute-level wrapper around LLM::Ollama for local model inference.

Adds environment-variable-based configuration so that all Brute examples and the CLI work out of the box with a local Ollama instance:

OLLAMA_HOST  — base URL (default: http://localhost:11434)
OLLAMA_MODEL — default model (default: llm.rb's default, currently qwen3:latest)

Examples:

Auto-detect via environment

export OLLAMA_HOST=http://localhost:11434
ruby examples/01_basic_agent.rb

Remote Ollama server

export OLLAMA_HOST=http://192.168.1.50:11434
export OLLAMA_MODEL=llama3.1:8b
ruby examples/02_fix_a_bug.rb
