本文是 OpenClaw 模型配置系列教程的第三篇,讲解多模型智能切换策略。
🎯 为什么需要多模型切换?
典型场景
- 💰 成本优化 – 简单问题用便宜模型,复杂问题用高级模型
- 🔄 故障转移 – 主模型不可用时自动切换备用
- ⚡ 性能平衡 – 根据响应时间动态选择模型
- 🎭 任务适配 – 不同任务类型使用不同专长模型
🔧 配置智能路由
基于任务复杂度路由
{
"routing": {
"strategy": "complexity-based",
"rules": [
{
"condition": "tokenCount < 100",
"model": "dashscope/qwen3-turbo"
},
{
"condition": "tokenCount < 1000",
"model": "dashscope/qwen3.5-plus"
},
{
"condition": "tokenCount >= 1000",
"model": "dashscope/qwen3-max"
}
]
}
}
基于任务类型路由
{
"routing": {
"strategy": "task-based",
"rules": [
{
"condition": "taskType == 'coding'",
"model": "dashscope-coding/qwen3.5-plus"
},
{
"condition": "taskType == 'vision'",
"model": "dashscope/qwen3-vl-plus"
},
{
"condition": "taskType == 'analysis'",
"model": "dashscope/qwen3-max"
}
]
}
}
基于成本路由
{
"routing": {
"strategy": "cost-optimized",
"budget": {
"dailyLimit": 100,
"monthlyLimit": 2000
},
"fallback": "dashscope/qwen3-turbo"
}
}
🔄 故障转移配置
自动故障转移
{
"agents": {
"defaults": {
"model": {
"primary": "dashscope/qwen3.5-plus",
"fallback": [
"dashscope/qwen3-max",
"openai/gpt-4",
"anthropic/claude-3"
],
"failover": {
"enabled": true,
"timeout": 30,
"retries": 3,
"backoff": "exponential"
}
}
}
}
}
故障检测策略
{
"healthCheck": {
"enabled": true,
"interval": 60,
"timeout": 10,
"endpoints": [
"https://dashscope.aliyuncs.com/health",
"https://api.openai.com/health"
]
}
}
⚖️ 负载均衡
轮询策略
{
"loadBalance": {
"strategy": "round-robin",
"models": [
"dashscope/qwen3.5-plus",
"openai/gpt-4",
"anthropic/claude-3"
]
}
}
加权轮询
{
"loadBalance": {
"strategy": "weighted-round-robin",
"models": [
{"name": "dashscope/qwen3.5-plus", "weight": 60},
{"name": "openai/gpt-4", "weight": 30},
{"name": "anthropic/claude-3", "weight": 10}
]
}
}
最少连接策略
{
"loadBalance": {
"strategy": "least-connections",
"models": [
"dashscope/qwen3.5-plus",
"openai/gpt-4"
]
}
}
💰 成本优化策略
分级定价配置
{
"costOptimization": {
"enabled": true,
"tiers": [
{
"name": "free",
"models": ["dashscope/qwen3-turbo"],
"dailyLimit": 1000
},
{
"name": "standard",
"models": ["dashscope/qwen3.5-plus"],
"dailyLimit": 5000
},
{
"name": "premium",
"models": ["dashscope/qwen3-max"],
"dailyLimit": 1000
}
]
}
}
预算告警
{
"budget": {
"daily": 50,
"monthly": 1000,
"alerts": [
{"threshold": 0.5, "action": "notify"},
{"threshold": 0.8, "action": "throttle"},
{"threshold": 1.0, "action": "stop"}
]
}
}
📊 监控与报告
实时监控
# 查看模型使用情况
openclaw metrics model-usage --realtime
# 查看成本统计
openclaw metrics cost --today
# 查看响应时间分布
openclaw metrics latency --histogram
生成报告
# 日报
openclaw report daily --date 2026-03-27
# 周报
openclaw report weekly --week 13
# 月报
openclaw report monthly --month 2026-03
🎯 最佳实践
1. 渐进式切换
不要一次性切换所有流量,逐步增加新模型的比例:
第 1 天:10% 流量 → 新模型
第 2 天:30% 流量 → 新模型
第 3 天:60% 流量 → 新模型
第 4 天:100% 流量 → 新模型
2. A/B 测试
同时运行多个模型,比较效果:
{
"abTest": {
"enabled": true,
"variants": [
{"model": "dashscope/qwen3.5-plus", "traffic": 50},
{"model": "openai/gpt-4", "traffic": 50}
],
"metrics": ["accuracy", "latency", "cost"]
}
}
3. 定期评估
每周评估模型表现,调整配置:
- 准确率是否达标?
- 响应时间是否可接受?
- 成本是否在预算内?
- 用户满意度如何?
