A carefully curated list of free LLM API resources covering mainstream models like Claude, Gemini, Llama, and OpenAI, helping users experience AI technology at zero cost.
Section 01
This article introduces the open-source project free-llm-api-resources, which collects legal free API resources for mainstream large language models such as Claude, Gemini, Llama, and OpenAI. It helps beginners, students, and developers with limited budgets experience AI technology at zero cost and lowers the threshold for innovation.
Section 02
With the explosion of phenomenal AI products like ChatGPT, developers and enterprises want to integrate LLM capabilities, but the threshold of paid APIs hinders innovation. The free-llm-api-resources project systematically collects and verifies free API resources to solve this pain point, providing practical value for AI education popularization, personal development, and technical verification for startups. It also continuously tracks policies to ensure information timeliness.
Section 03
Known for long text processing and security; the list includes channels to obtain free quotas.
Multimodal models; the list explains free quotas on platforms like Google AI Studio.
Open-source weight models; multiple free inference service platforms are included.
Industry-leading GPT models; information on official and third-party free trial quotas is organized.
Section 04
Usage Methods: Zero threshold—no programming background required. Browse the project page to get API links and registration guidelines. Target Audience: AI enthusiasts, students (course practice), independent developers (reduce verification costs), startup teams (early function verification), non-technical users (learn about AI).
