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.

Awesome-free-llm-apis
What is this?A curated list of LLM APIs that offer permanent free tiers for text inference. Every entry links straight to the provider's API key page, so you can register and start calling models at no cost.
Is this a catalog I browse, or do I install something?It's a reference list on GitHub, not a tool to install. You browse the tables, pick a provider and sign up on its own site — nothing in this repo needs to be installed or run.
Where should I start if I just want to try something today?Start with the zero-friction ones: Kilo Code requires no credit card and no API key (an auto-router picks free models for you), and LLM7.io allows anonymous access without a token.
What's the catch with these free tiers?Rate limits and data-use caveats. Google may use free-tier prompts to improve its products, Mistral may train on free-mode prompts unless you opt out, and Cohere's trial key is non-commercial only.
Which big-name models can I actually use for free?Highlights include Google Gemini 2.5 Pro with a 1M-token context, OpenAI's open-weight gpt-oss-120b (on Groq, NVIDIA NIM, OpenRouter and Cloudflare), Cohere Command A+, DeepSeek R1 distills and Z AI's GLM-4.7-Flash.
Can these free APIs handle images and audio, or text only?Several are multimodal: Gemini Flash models accept text, image, audio and video, Mistral's free models handle text, image and code, and NVIDIA NIM's catalog adds video, speech and embeddings.
How generous are the free quotas in practice?It varies a lot: NVIDIA NIM allows up to 10,000 requests per model per day, Gemini Flash around 1,500/day, Kilo Code 200 requests/hour, while OpenRouter free models cap at 50/day — fine for hobby use, tight for production.
