为什么需要这个项目

找一个免费 LLM API，不应该翻十几个 GitHub README、注册五个不同平台、或者猜测哪些模型还有免费额度。

这个仓库是一个结构化、机器可读的免费 LLM API 目录 — 包含速率限制、上下文窗口、一键配置代码片段和直达 API 密钥链接。每日更新。

为什么选择这个仓库 + freellm.net：

  • ✅ 始终最新 — 数据每日自动化监控更新，不是两年前的静态列表
  • ✅ 信用卡透明 — 清晰标注哪些提供商需要信用卡、手机验证，哪些完全无需
  • ✅ 一键配置 — 即用代码片段覆盖 Claude Code、Cursor、Codex、Aider 等 10+ 工具
  • ✅ 并排对比 — 即时对比各提供商的上下文窗口、速率限制和多模态能力

三步上手

  1. 选一个提供商 — 看下方 Provider Directory。推荐从 Groq 开始（免信用卡，30 RPM 免费）。
  2. 获取 API Key — 点下方 Quick Reference 里任意一个 [Get Key →] 链接，注册（大多只需邮箱），复制 key。不到 1 分钟。
  3. 填入代码 — 复制 base URL + model ID，粘贴到下边的 Quick Start 示例。

配置具体工具？Claude Code · Cursor · Codex · OpenHuman · OpenCode · OpenClaw — 一键配置在 freellm.net/config/。

快速上手 — 30 秒接入免费 API

没用过 API？ 最简单的方式：打开 console.groq.com/keys，用邮箱注册（无需信用卡），复制免费 key，粘贴到下面任意示例。不到一分钟就能跑起来。

以下所有提供商都暴露了 OpenAI 兼容接口。任何接受 baseURL + apiKey 的工具都能直接用 — 替换 base URL 和 key 即可。

Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    base_url="https://api.groq.com/openai/v1",  # 免费，无需信用卡
    api_key="GROQ_API_KEY",                     # 获取: console.groq.com/keys
)

response = client.chat.completions.create(
    model="llama-3.3-70b-versatile",            # 模型列表见下方 Best Models 表
    messages=[{"role": "user", "content": "你好！"}],
)
print(response.choices[0].message.content)
# Groq 免费额度: 30 RPM, 14,400 RPD — 个人使用绰绰有余

Codex CLI

export OPENAI_BASE_URL="https://api.groq.com/openai/v1"
export OPENAI_API_KEY="your-groq-key"          # 获取: console.groq.com/keys
codex --model "llama-3.3-70b-versatile"

Cursor

Settings → Models → Add Model
  Model name: llama-3.3-70b-versatile
  Base URL: https://api.groq.com/openai/v1
  API key: your-groq-key                       # 获取: console.groq.com/keys

Claude Code

# Claude Code 需要 Anthropic 兼容接口 — 使用 OpenRouter
export ANTHROPIC_BASE_URL="https://openrouter.ai/api"
export ANTHROPIC_AUTH_TOKEN="sk-or-v1-your-key"  # openrouter.ai/keys
export ANTHROPIC_API_KEY=""                       # 必须为空
# 注意: OpenRouter 的 Anthropic 模型需充值 $10（一次性）

其他工具？

大多数 AI 开发工具都接受自定义 API 端点 — 拿到免费 key 后：
