Start Darce in your project with GPT-5.6 Sol:
npm install -g darce-cli
darce --model openai/gpt-5.6-solAlready in a session? Type /model openai/gpt-5.6-sol, or open the picker with Ctrl+P. Darce then reads your code, edits files and runs commands with GPT-5.6 Sol; risky commands ask first, and /undo reverses any change, including what shell commands did. No account yet? npx darce-cli lets you try it free. Which plan includes which models is on the pricing page.
Make it your default or a gear
In ~/.darcerc, set it as the starting model or add it to the gears you move between with Shift+↑ / Shift+↓ (see configuration):
{
"router": { "default": "openai/gpt-5.6-sol" },
"gears": ["qwen/qwen3-coder", "openai/gpt-5.6-sol"]
}Compare it on your own code
Benchmarks rarely match your repository. Race GPT-5.6 Sol against two other models on a real task and keep the best diff:
