MistralAI推出API免费套餐已有几天,一直犹豫不觉是否发出来的原因是Mistral已经多次忽悠开发者...8月底本来说9月不订阅计划就用不了,结果在9月17日直接将大部分模型免费开放。
直接访问 https://console.mistral.ai/ ,进入计费页面开通。
加入免费计划首先要通过电话验证,这里我已经认证过了。使用谷歌虚拟号码,国内手机号也支持输入,不过我没有试。
找半天免费套餐有什么限制,也没找到,最后只看到一份可使用的模型型号限制说明,如下:
Mistral 提供两种类型的模型:免费模型和高级模型。

看来免费的都可以用,请求地址格式:https://api.mistral.ai/v1/chat/completions
然后直接创建密钥即可使用:
注意:他们家 api 不支持惩罚参数,可以搞个 worker 屏蔽掉,否则在很多终端中可能异常。
mistral 过滤不支持字段 worker 脚本(更新 cors 跨域处理):
/**
Welcome to Cloudflare Workers! This is your first worker. *
Run "npm run dev" in your terminal to start a development server
Open a browser tab at http://localhost:8787/ to see your worker in action
Run "npm run deploy" to publish your worker *

export default {
async fetch(request, env) {
// 处理预检请求
if (request.method === 'OPTIONS') {
return handleOptions(request);
}
const url = new URL(request.url);
url.host = 'api.mistral.ai';
let body;
try {
// 获取 body 数据并解析为 JSON
body = await request.json();
} catch (error) {
return new Response('Invalid JSON', { status: 400 });
}
// 定义支持字段列表
const allowedFields = ['model', 'messages', 'temperature', 'topp', 'maxtokens', 'mintokens', 'stream', 'stop', 'randomseed','responseformat','tools','toolchoice','safe_prompt'];
// 过滤 body 中不在支持字段列表中的字段
const filteredBody = filterFields(body, allowedFields);
const newBody = JSON.stringify(filteredBody);
const modifiedRequest = new Request(url, {
method: request.method,
body: newBody,
headers: request.headers
});
return fetch(modifiedRequest);
}
}
// 过滤不支持参数
function filterFields(obj, allowedFields) {
let result = {};
for (const key in obj) {
if (allowedFields.includes(key)) {
result[key] = obj[key];
}
}
return result;
}
// 处理预检请求的函数
function handleOptions(request) {
const headers = {
'Access-Control-Allow-Origin': '*', // 允许所有来源
'Access-Control-Allow-Methods': 'GET, POST, OPTIONS', // 允许的方法
'Access-Control-Allow-Headers': 'Content-Type, Authorization', // 允许的头部
'Access-Control-Max-Age': '86400', // 预检请求的缓存时间(秒)
};
return new Response(null, {
status: 204,
headers: headers
});
}
免费的代码模型需要单独申请密钥使用
虽然目前国内有很多价格及低、性能也不错的模型(DeepSeek),甚至也有免费的大模型API(智谱清言)但免费也要优中选优嘛。
Mistral有专精代码的模型Codestral,上面内容已经介绍,LMSYS 排名挺高,可以接入到Cursor试试,用起来感觉还行。
