Awesome Free LLM APIs

Awesome

LLM APIs with permanent free tiers for text inference.

All endpoints are OpenAI SDK-compatible unless noted. Each link points to the provider's API key page.

Manifest

All of those free LLM APIs are available at manifest.build - make reliable agents.

这是什么东西?一份精心整理的大模型(LLM)API 清单,收录的都是提供永久免费额度的服务商。每个条目都直接链接到服务商的 API 密钥页面,注册后就能免费调用模型。
这是个用来浏览的目录,还是需要安装什么软件?它是 GitHub 上的参考资料清单,不是需要安装的工具。你只需要浏览表格、挑一个服务商,然后到它自己的网站上注册——这个仓库里的东西都不需要安装或运行。
我今天就想试用一下,应该从哪里入手?从最省事的开始:Kilo Code 不需要信用卡也不需要 API 密钥(会由自动路由帮你选免费模型),LLM7.io 则无需令牌就能匿名访问。
这些免费额度有什么限制?主要有调用频率限制和数据使用方面的注意事项。Google 可能会用免费档位的提示词来改进自己的产品,Mistral 可能会在免费模式的提示词上训练模型(除非你主动选择退出),而 Cohere 的试用密钥只能用于非商业用途。
有哪些知名的大模型可以真正免费用到?亮点包括:支持 100 万 token 上下文的 Google Gemini 2.5 Pro,OpenAI 的开放权重模型 gpt-oss-120b(可在 Groq、NVIDIA NIM、OpenRouter 和 Cloudflare 上使用),还有 Cohere Command A+、DeepSeek R1 蒸馏版,以及智谱 Z AI 的 GLM-4.7-Flash。
这些免费 API 能处理图片和音频吗,还是只能处理文本?有好几个支持多模态:Gemini Flash 系列模型可以处理文本、图片、音频和视频,Mistral 的免费模型支持文本、图片和代码,NVIDIA NIM 的模型目录还包括视频、语音和向量嵌入(embeddings)。
实际用起来,免费额度大概有多少?差别很大:NVIDIA NIM 每个模型每天最多可调用 10,000 次,Gemini Flash 大约每天 1,500 次,Kilo Code 每小时 200 次,而 OpenRouter 的免费模型每天上限只有 50 次——个人玩玩够用,生产环境就很紧张了。
