Considering that many people don't have the ability to pay for large model coding plans, just like me, haha, so I often look for various free LLM API welfare sites. Today I've organized and shared them here, which include chatgpt, claude, gemini, grok, glm, mimo, kimi and other large models.
Due to the nature of welfare, availability is not guaranteed However, I myself occasionally take advantage of the free credits, so I'm sharing them with everyone, updating irregularly. The following sites were all verified to be available at the time of testing, and availability is not guaranteed. If you encounter any invalid welfare sites, please leave a message in the comments section, and I will remove the corresponding welfare sites. The last two are generally available for a long time. I don't know which two benevolent donors provide them, but I've been using them all the time.
Relay
Relay provides GPT and Gemini large models. New users registering can get a free $0.5, which is equivalent to the official $15 free quota. It needs to pass Telegram verification to be usable. It's not counted as a welfare site, but it's stable.
MarsAI
MarsAI offers a free quota of 1M tokens for new users. The official models are mainly Claude, Codex and other mainstream models. The models are very powerful. After registering, you can use Discord to use the Mars CLI. If you need API calls, you need to verify through Telegram.

CodeCraft
CodeCraft provides 1 million tokens per month. Although it's not much, their models are really good. GPT-5.6 Luna, Claude family bucket, domestic high-end models, available in all categories, updated on September 25, 2026. If you're interested, please click https://codecraftapi.com to register one.

Configure it with the official key. Here we test it with claude-sonnet-5. I configured it with claude myself, but it didn't work. However, opencode is available.

Mimo is an AI programming terminal developed by Xiaomi based on OpenCode. Currently, MiMo-V2.6-flash is free. The official channel is stable and available. Just install the mimo cli.
anyrouter
This site doesn't know which supernatural ancestor provides it. It supports claude, codex official large models, and also supports the latest claude opus 4.8. I often used it at first. Up to now, I have accumulated $3000 in sign-in credits.
Note that if you keep reporting the error API Error, you can configure the following environment variables: ANTHROPIC_CUSTOM_HEADERS: x-stainless-os: Windows
{ "env": { "ANTHROPIC_CUSTOM_HEADERS": "x-stainless-os: Windows" }}Codex is also available:
agentrouter
agentrouter is also a relatively old welfare site. It was from the same period as anyrouter. At present, it also provides large models such as claude, gpt5.5, glm5.2. The models are quite powerful. Address: https://agentrouter.org/login
Summary
The large model API welfare site is a site opened for free by the station master. The availability is not high. It is often unavailable due to upstream account restrictions or account quota being used up. But we still want to ask for something free, let's leave a message in the message area if you can't use it, and I'll remove it. If you also have relevant free large model API welfare sites, please leave a message in the message area, and I will update it in the article.
