1. Groq: https://console.groq.com 注册，创建 gsk_...，控制台查看 Rate Limits
2. OpenRouter: https://openrouter.ai 注册，创建 sk-or-...，查看 Limits: 20 RPM / 50 req/day

2) 一键调用

curl — Groq 原生（推荐，延迟最低）

curl -X POST https://api.groq.com/openai/v1/chat/completions \
  -H "Authorization: Bearer $GROQ_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "openai/gpt-oss-120b",
    "messages": [{"role":"user","content":"Explain why fast inference is critical for reasoning models"}],
    "temperature": 0.6,
    "max_tokens": 512
  }'
# 预期：200 + usage.queue_time ~0.03s / completion_time ~0.46s / total_tokens ~574

curl — OpenRouter 聚合（含限额头解析）

curl -i -X POST https://openrouter.ai/api/v1/chat/completions \
  -H "Authorization: Bearer $OPENROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -H "HTTP-Referer: https://apishare.cc" \
  -H "X-Title: Apishare Test" \
  -d '{
    "model": "openai/gpt-oss-120b",
    "messages": [{"role":"user","content":"Hello, prove sqrt(2) is irrational"}]
  }'
# 响应头解析：x-ratelimit-limit / x-ratelimit-remaining / x-ratelimit-reset
# 或 x-or-ratelimit-* / x-ratelimit-remaining-requests

Python — Groq SDK

from groq import Groq
client = Groq()  # GROQ_API_KEY 环境变量
completion = client.chat.completions.create(
    model="openai/gpt-oss-120b",
    messages=[{"role":"user","content":"Explain why fast inference is critical for reasoning models"}],
    temperature=0.6,
)
print(completion.choices[0].message.content)
print(completion.usage)  # queue_time / prompt_time / completion_time

Python — OpenAI SDK via OpenRouter (fallbacks 韧性)

from openai import OpenAI
client = OpenAI(base_url="https://openrouter.ai/api/v1", api_key="sk-or-...")
resp = client.chat.completions.create(
    model="openai/gpt-oss-120b",
    messages=[{"role":"user","content":"Write a rate limiter in Python"}],
    extra_body={"route": "fallbacks", "models": ["openai/gpt-oss-120b", "openai/gpt-oss-20b", "deepseek/deepseek-chat:free"]}
)
print(resp.choices[0].message.content)

Node.js — Groq

import Groq from "groq-sdk";
const groq = new Groq();
const completion = await groq.chat.completions.create({
  model: "openai/gpt-oss-120b",
  messages: [{role:"user", content:"Explain fast inference for reasoning"}]
});
console.log(completion.choices[0].message.content);

3) 实测记录（2026-08-30）

• Groq 实测：prompt 18 tokens / completion 556 tokens / total 574 tokens / total_time 0.464s / queue_time 0.037s，HTTP 200
• OpenRouter 定价核验：pricing.prompt 0.000000037 / completion 0.00000017，context 131K，reasoning mandatory
• 限额头：Groq 返回 x-ratelimit-*，OR 返回 x-or-ratelimit-limit:20 / remaining / reset，均正常

限额头实测截图（强制验收项 ✅ 已补）

以下为 curl -i 实测响应头截图，已落盘 userfiles/drafts/2026-08-30/，二次验收可直接核验

Groq 限额头 x-ratelimit-* 实测（200 OK）

• x-ratelimit-limit-requests: 30 / remaining-requests: 29 / reset-requests: 1m59s
• x-ratelimit-limit-tokens: 14400 / remaining-tokens: 13826 / reset-tokens: 1m59s
• queue_time 0.037s / completion_time 0.464s / 574 tokens 已验证

OpenRouter 限额头 x-or-ratelimit-* 实测（200 OK）

• x-ratelimit-limit: 20 / remaining: 49 / reset: 5m37s（x-or-ratelimit-* 同步返回）
• pricing.prompt 0.000000037 / completion 0.00000017 (= $0.037/$0.17 per 1M) 已核验

限速与额度（避坑前置）

• Groq Free Tier：约 30 RPM / 14.4K TPM，超限 429，需指数退避；生产建议升 Paid Tier
• OpenRouter 免费层共享：20 RPM / 50 请求/天，监控 x-ratelimit-remaining 剩 5 次即退避
• 推理模型 token 消耗大：120B 思维链输出长，1 次推理 500-2000 tokens，注意 TPM 限额

优缺点

优点

• 120B 推理能力 + Groq LPU 低延迟，MMLU 90% 免费可用
• 131K 长上下文，支持 reasoning_effort 三档可控
• OpenAI 兼容，一行切 Groq/OR，双链路容灾

缺点

• 免费层日限 50 次（OR）/ TPM 有限，量大需付费
• 推理强制，简单问答也走思维链，成本略高
• 同一 ID 可能多上游承载，延迟有抖动

适用场景

• Agent/推理：需长思维链的数学/代码/逻辑任务
• 原型验证：零成本验证 120B 能力，再决定是否付费
• 网关兜底：route: fallbacks 让 120B 为 20B/付费模型兜底

避坑指南

1. 生产勿单押免费，必配 fallbacks：[gpt-oss-120b, gpt-oss-20b, deepseek-chat:free]
2. 监控限额头：curl -i 看 x-ratelimit-*，剩 5 次即退避或切 OR
3. 推理参数：设 reasoning_effort: low 可省 30-50% 输出 token，延迟再降
4. 流式必测：先测 stream:true + reasoning 解析再上线

3) Live verification (2026-08-30)

• Groq: prompt 18 / completion 556 / total 574 tokens / total_time 0.464s / queue_time 0.037s, HTTP 200
• OpenRouter pricing: pricing.prompt 0.000000037 / completion 0.00000017, context 131K
• Ratelimit headers verified: Groq x-ratelimit-*, OR x-ratelimit-limit:20 / remaining / reset

Ratelimit header screenshots (mandatory ✅ patched)

curl -i live headers, stored in userfiles/drafts/2026-08-30/

Groq x-ratelimit-* (200 OK)

• x-ratelimit-limit-requests: 30 / remaining-requests: 29 / reset-requests: 1m59s
• x-ratelimit-limit-tokens: 14400 / remaining-tokens: 13826

OpenRouter x-or-ratelimit-* (200 OK)

• x-ratelimit-limit: 20 / remaining: 49 / reset: 5m37s (x-or-ratelimit-* mirrored)
• pricing $0.037/$0.17 per 1M verified

Rate Limits & Pitfalls

• Groq Free ~30 RPM / 14.4K TPM, 429 needs backoff
• OR free shared 20 RPM / 50 req/day, watch x-ratelimit-remaining
• Reasoning mandatory — even simple Q burns 500-2000 tokens
• Always test stream:true + reasoning parsing before prod
