StepFun 上线新模型后,扩展会在下次启动时自动拉取,无需手动更新。
git clone https://github.com/V-dev-388/pi-stepfun.git ~/.pi/agent/extensions/stepfun
cd ~/.pi/agent/extensions/stepfun
mkdir -p ~/.pi/agent/extensions
ln -s ~/project/pi-stepfun ~/.pi/agent/extensions/stepfun
pi install git:github.com/V-dev-388/pi-stepfun
pi install npm:@v_dev_338/pi-stepfun
编辑 src/index.ts,把 YOUR_STEPFUN_API_KEY 替换为你的 StepFun API Key:
const STEPFUN_API_KEY = "YOUR_STEPFUN_API_KEY";
或者在 settings.json 中通过环境变量引用:
{
"defaultProvider": "stepfun",
"defaultModel": "step-3.7-flash"
}
export STEPFUN_API_KEY="your-key"
pi
启动 Pi,扩展会自动加载并注册所有模型:
pi --model stepfun/step-3.7-flash
切换模型:
/model stepfun/step-3.5-flash
调整推理强度:
pi --thinking high --model stepfun/step-3.7-flash
支持 off / minimal / low / medium / high / xhigh / max 七档,全部映射到 StepFun 的 low / medium / high 三档。
pi update --models
扩展在 Pi 启动时:
GET https://api.stepfun.com/step_plan/v1/models 获取全量模型列表pi.registerProvider() 注册到 Pi 的模型运行时pi-stepfun/
