Baidu PaddlePaddle AI Studio LLM API (1 million Tokens per developer)

AI Studio gives every developer a free quota of 1 million Tokens, usable through an OpenAI-compatible interface with models such as ERNIE 5.1 / 5.0 / 4.5, DeepSeek V3 / R1, Kimi-K2, and Qwen3-Coder

Official help-doc verbatim: Tokens are the basic unit of measurement for calling large model SDKs or using large model applications on the Baidu AI Studio. AI Studio provides each developer with a free quota of 1 million Tokens. Developers will be charged a different number of Tokens for using different models. (Different models deduct different numbers of Tokens; you can check usage on the Token management page, and once the quota is used up you can buy more Tokens to keep going.) How to connect: use the "access token" from your AI Studio personal center as the api_key, set base_url to https://aistudio.baidu.com/llm/lmapi/v3, and call it with openai-python. The text models listed in the official docs include ERNIE 5.1 (ernie-5.1), ERNIE 5.0, ERNIE 4.5 Turbo, DeepSeek-V3 (deepseek-v3), Kimi-K2 (kimi-k2-instruct), and Qwen3-Coder (qwen3-coder-30b-a3b-instruct); the thinking models include ERNIE 5.1 Thinking Preview, ERNIE X1.1 preview, and DeepSeek-R1.

⚠️The official docs only say "1 million Tokens free quota per developer" and do not say whether it is one-time or resets monthly, nor give a validity period; secondhand sources mention "monthly", but no original wording was found on the official pages, so this entry conservatively treats it as a one-time quota; after claiming, go by what the Token management page shows. You need to log in to AI Studio with a Baidu account; the official docs do not mention a real-name verification requirement. Different models deduct Tokens at different rates, and flagship models burn through them faster.
