If you have both ollama and llama.cpp installed on your MBP, and are interested in utilizing your local model as a cost-saving preprocessor for your frontier models, consider using https://github.com/Standard-Pentest/kultivait!
"kultivait init --setup" to evaluate your machine's hardware, access to frontier cli-tools, download models, and create a proxy for ollama to get started. works great with opencode!
