白嫖 OpenRouter 免费模型

众所周知，OpenRouter 是 AI 领域有名的大善人 —— 它每天都会提供大量真免费的模型额度，而不是像很多平台那样，打着"打折"、"免费"的幌子吸引流量，用起来又慢又卡。OpenRouter 是实打实地把额度发出来，在 API Router 赛道全球口碑第一，许多模型厂商为了测试最新的大模型，也会接入 OpenRouter。

于是就出现了这样一种情况:你完全可以一分钱不花，免费用上最新最好用的大模型。唯一的限制是:免费账号每天 50 次请求 —— 用来帮你解决临时问题，相当足够了。如果你升级到 Pay-as-you-go 计划(也就是最少充值 $10)，所有免费模型的额度会变成 每天 1000 次请求。

STEP ONE

在 OpenRouter 注册并申请 API Key

打开 openrouter.ai 注册账号，登录后点击右上角 Get API Key 创建一个新的 API Key 并复制下来。

然后在顶部搜索框输入 free，会列出所有当前免费可用的模型。挑一个你想用的(比如最新的 deepseek / qwen / llama 系列)，把它的模型 ID 也复制下来 —— 一般长这样:deepseek/deepseek-v4-flash。

注意:OpenRouter 的免费模型 ID 在结尾会有 :free 后缀, 粘贴时不要带这个后缀。

STEP TWO

在 EchoBird「模型中心」里添加 OpenRouter

打开 EchoBird，左侧进入 模型中心，在右侧栏切换到 模型中转站 标签 —— 第一个就是 OpenRouter。点击它旁边的 + 按钮。

在弹出的「编辑模型配置」窗口里:

① 名称就是个标签，你能认出来就行，随便起。
② 模型 ID 才是真正传给 API 的字段，粘贴刚才复制的那个，例如 deepseek/deepseek-v4-flash，把结尾的 :free 去掉 —— EchoBird 会自动帮你走免费通道。
③ OpenAI 地址 已经自动填好，无需改动。
④ API 密钥 粘贴你在 OpenRouter 申请的那个 Key。
⑤ 点保存。

提示:同一个 API Key 可以反复添加不同的模型，每个模型独立配置一行，随时在「应用管理」、「我的 AI 项目」、「安装与修复」里切换使用。

STEP THREE

进入「安装与修复」实测一下

切到左侧的 安装与修复 页面，在右下角的模型选择器里挑刚才添加的那个 OpenRouter 模型，随便聊一句、跑一个快速指令试试 —— 你会发现免费的速度也相当快，完全可以拿来日常解决一些临时问题。

遇到 429 / 配额用完的提示就是当天 50 次用满了，等明天自动重置; 或者升级 Pay-as-you-go 把额度推到 1000 次/天。

Free LLMs on OpenRouter

OpenRouter is the most generous host in the AI space — it ships a real, daily free tier across a huge pool of models, not the bait-and-switch "free" that other platforms use to harvest traffic and then choke you with throttled latency. It is consistently ranked #1 globally in the API Router category, and many model vendors plug their newest releases into OpenRouter just to A/B-test them in the wild.

The result: you can run the latest, top-tier LLMs without paying a cent. The only cap is 50 requests/day on a free account — plenty for the day's quick problems. Top up the account into the Pay-as-you-go tier (a one-time $10 minimum) and every free model bumps up to 1,000 requests/day.

STEP ONE

Sign up and grab an API key

Head to openrouter.ai, create an account, then click Get API Key in the top right. Generate a key and copy it somewhere safe.

Type free in the search box at the top — every currently-free model will show up. Pick one you want to try (the newest deepseek / qwen / llama family is a good start) and copy its model ID. It looks like deepseek/deepseek-v4-flash.

Heads up: Free models on OpenRouter show a :free suffix — strip it before pasting.

STEP TWO

Add OpenRouter inside EchoBird's Model Nexus

Open EchoBird, go to Model Nexus in the left sidebar, then switch the right-side pane to the Model Relays tab. OpenRouter is the first entry. Click the + button next to it.

In the "Edit Model Config" dialog:

① Name is just a label — type anything you'll recognise.
② Model ID is the field that gets sent to the API — paste the ID you copied, e.g. deepseek/deepseek-v4-flash, and strip the :free suffix. EchoBird routes free traffic for you.
③ OpenAI URL is pre-filled — leave it alone.
④ API Key: paste the OpenRouter key.
⑤ Hit Save.

Tip: One key can back as many models as you want — add a separate row per model and switch freely from App Manager / My AI Projects / Install & Repair.

STEP THREE

Try it from Install & Repair

Jump to Install & Repair on the left, pick the OpenRouter model from the model selector at the bottom right, and send a quick message — free latency is genuinely fast. It is more than enough for everyday quick-fix prompts.

If you see a 429 / quota error, you have hit the 50-request daily cap — it resets next day. Or upgrade to Pay-as-you-go to bump it to 1,000/day.
