Free LLM API Hub

Free LLM API Hub is an open dataset and web explorer that tracks free LLM APIs and adjacent model APIs for image, speech, embeddings, rerank and OCR. The repository carries an MIT license with copyright credited to Tweakeo, Inc. and contributors. Each entry is dated and sourced to the provider's own documentation, and the project says unconfirmed details are marked rather than hidden.

What It Is

The hub is a maintained reference for developers picking an API to prototype on. Providers are split into ongoing free tiers (a quota that renews, a permanently free model, or a recurring credit) and trial credits that run out. The site's explorer lists 68 providers, with the fine print for each, such as card or phone requirements, commercial-use status, and OpenAI-compatibility.

How the Data Is Verified

Every verified entry carries a last-verified date and a link to the provider's own docs. The README says freshness is computed from the data against a 90-day SLA and graded on the oldest entry, and that the dataset is schema-validated in CI. Entries that could not be independently confirmed are marked as unverified. The README states that AI agents help with routine maintenance under human review, with a maintainer approving every merge.

Using the Data

The canonical dataset is data/providers.json, validated against a JSON schema. It is also published as a static JSON API, an llms.txt file, an RSS feed and an embeddable widget. Explorer filters include no card, no phone, commercial use, OpenAI-compatible, and models that do not train on prompts. Curated collections and guides cover needs such as permanently free APIs, multimodal APIs and EU hosting. The project is independent and not affiliated with any listed provider.
