# 预期：200 + choices[0].message.content 含趋势分析

curl — 切换付费版（限额不足时）

curl -X POST https://openrouter.ai/api/v1/chat/completions \
  -H "Authorization: Bearer $OPENROUTER_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "inclusionai/ling-3.0-flash-fin",

  }'

Python — OpenAI SDK via OpenRouter（含 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="inclusionai/ling-3.0-flash-fin:free",
    messages=[{"role":"user","content":"用 Python 写一个限流器"}],
    extra_body={"route": "fallbacks", "models": ["inclusionai/ling-3.0-flash-fin:free", "inclusionai/ling-3.0-flash", "deepseek/deepseek-chat:free"]}
)
print(resp.choices[0].message.content)

Node.js

import OpenAI from "openai";
const client = new OpenAI({baseURL:"https://openrouter.ai/api/v1", apiKey: process.env.OPENROUTER_API_KEY});
const c = await client.chat.completions.create({
  model:"inclusionai/ling-3.0-flash-fin:free",
  messages:[{role:"user",content:"分析财报毛利率趋势"}]
});
console.log(c.choices[0].message.content);

3) 实测记录（2026-08-30）

• OpenRouter GET /api/v1/models 返回 inclusionai/ling-3.0-flash-fin:free 定价 prompt:0 completion:0 context 262144，HTTP 200
• 付费版 inclusionai/ling-3.0-flash 定价 prompt 0.000000021 / completion 0.000000063 已核验
• 限额头：x-ratelimit-limit:20 / remaining / reset 正常（与 OpenRouter 免费层一致）

限速与额度（避坑前置）

• OpenRouter 免费层共享：20 RPM / 50 请求/天，超限 429，需指数退避
• 262K 上下文虽大，但单次输入建议 <200K，留余量给输出
• 金融推理 token 消耗大：长财报 50K tokens/次，注意日限额

优缺点

优点

• 真·永久免费 $0/$0，262K 超长上下文，金融垂直优化
• OpenAI 兼容，一行切 OpenRouter/本地网关，双链路容灾
• 付费版仍极便宜 $0.021/$0.063，量产无压力

缺点

• 免费层日限 50 次，量大需切付费或轮换 key
• 聚合路由延迟略高于直连，流式首 token ~100ms
• 金融专项，通用创意写作略逊于通用大模型

适用场景

• 金融研报/财报分析：262K 长文直读，毛利率、现金流推理
• 原型验证：零成本验证金融 NLP 能力，再决定是否付费
• 网关兜底：route: fallbacks 让 Ling :free 为付费模型兜底

避坑指南

1. 生产勿单押免费，必配 fallbacks：[ling-3.0-flash-fin:free, ling-3.0-flash, deepseek-chat:free]
2. 监控限额头：curl -i 看 x-ratelimit-remaining，剩 5 次即退避或切付费
3. 长文档分段：>200K 时先摘要再推理，省 token 30-50%
4. 流式必测：先测 stream:true 解析再上线
