事实上，就算充了钱，免费模型的限制也很多，很容易就会触发使用限制  
相关文档的说明如下，每分钟20次请求，很容易超量

> There are a few rate limits that apply to certain types of requests, regardless of account status:
> 
> 1. Free usage limits: If you’re using a free model variant (with an ID ending in `:free`), you can make up to 20 requests per minute. The following per-day limits apply:
> 
> - If you have purchased less than 10 credits, you’re limited to 50 `:free` model requests per day.
> - If you purchase at least 10 credits, your daily limit is increased to 1000 `:free` model requests per day.
> 
> 1. **DDoS protection** : Cloudflare’s DDoS protection will block requests that dramatically exceed reasonable usage.

openrouter并非无限量免费（当然了），没有充值的情况下很快就达到免费额度了（具体多少我不知道）

这时候请求会报错

```auto
Job exception: {"error":{"message":"Rate limit exceeded: free-models-per-day. Add 10 credits to unlock 1000 free model requests per day","code":429,"metadata":{"headers":{"X-RateLimit-Limit":"50","X-RateLimit-Remaining":"0","X-RateLimit-Reset":"xxxxx"},"provider_name":null}},"user_id":"user_xxxxx"}

```

充了10美元，又可以每天免费请求1000次了

# 在dify里使用openrouter免费的deepseek v3.1

在dify里点开设置

选择模型供应商，搜索openrouter

配置好以后你就可以看到openrouter支持使用的一大堆模型

但是要注意，默认的这些模型里，deepseekv3.1是收费的

你需要手动再添加

模型名称复制这个：`deepseek/deepseek-chat-v3.1:free`  
key还是之前申请的key  
其他设置保持默认，不懂就不要更改
