开发者正在搜索的 AI API 问题
基于公开 Quora、Reddit、Google 搜索意图建立的 answer-first 承接页。不搬运社区答案,只给结论、步骤、provider 内链、价格路径和 OpenAI 兼容接入说明。
不用信用卡,哪个免费 AI API 最适合先试?
想最快拿 key 先试,用 OpenRouter 免费模型;人在国内优先硅基流动或智谱 GLM;想要大额中文/代码模型测试,用通义千问百炼额度。真正上线前,要提前准备付费兜底。
Score 92现在最便宜的 LLM API 是哪个?
大多数文本和代码任务,先测 DeepSeek 或通义千问;需要国内直连开源模型,优先硅基流动;需要快速横向比较多模型,用 OpenRouter,但要接受聚合平台加价。本地部署通常只有高利用率才更便宜。
Score 90哪个 OpenAI 兼容 API 最适合替代 OpenAI?
想低成本替换,优先 DeepSeek;想国内直连和中文/代码能力,选通义千问、硅基流动或智谱;想极低延迟,选 Groq;想一个 key 试很多模型,选 OpenRouter。真正的兼容替换应该只改 base_url、api_key 和 model 名称。
Score 88国内开发者能直接用 Claude API 吗?
Claude API 在中国大陆直连通常不稳定或不可用。生产环境优先走官方可用账号/账单路径;不行就用合规 API 中转,或改用通义千问、DeepSeek、智谱、硅基流动等国内直连模型。不要购买共享 key 或绕平台规则。
Score 86Qwen 和 GLM API 怎么用 OpenAI SDK 接入?
通义千问用 DashScope compatible mode:https://dashscope.aliyuncs.com/compatible-mode/v1;智谱 GLM 用 https://open.bigmodel.cn/api/paas/v4。两者都可以继续用 OpenAI SDK,只改 base_url、api_key、model 名称,然后跑一个小 prompt 验证。
