Why This Exists

Finding a free LLM API shouldn't mean hunting through a dozen GitHub READMEs, signing up for five different platforms, or guessing which models still have a free tier.

This repo is a structured, machine-readable directory of every free LLM API — rate limits, context windows, one-click config snippets, and direct API key links. Updated daily.

Why this repo + freellm.net:

• ✅ Always up-to-date — data refreshed daily via automated monitoring, not a 2-year-old static list
• ✅ Credit card transparency — clearly shows which providers require a card, phone verification, or nothing at all
• ✅ One-click configs — ready-to-copy snippets for Claude Code, Cursor, Codex, Aider, and 10+ more tools
• ✅ Side-by-side comparison — compare context windows, rate limits, and modalities across providers instantly

How to Use — 3 Steps

1. Pick a provider — see Provider Directory below. Start with Groq (no credit card, 30 RPM free).
2. Get your API key — click any Get Key → link below, sign up (most need just an email), and copy your key. Takes < 1 minute.
3. Plug it in — copy the base URL + model ID, paste into the Quick Start examples below.

Configuring a specific tool? Claude Code · Cursor · Codex · OpenHuman · OpenCode · OpenClaw — one-click configs at freellm.net/config/.

Quick Start — Use Any Free API in 30 Seconds

Never used an API before? Here's the simplest path: go to console.groq.com/keys, sign up with just an email (no credit card), copy your free key, and paste it into any example below. You'll be running in under a minute.

All providers below expose an OpenAI-compatible endpoint. Any tool that accepts baseURL + apiKey works — just swap the base URL and key.

Python (OpenAI SDK)

from openai import OpenAI

client = OpenAI(
    base_url="https://api.groq.com/openai/v1",  # free, no credit card
    api_key="GROQ_API_KEY",                     # get at console.groq.com/keys
)

response = client.chat.completions.create(
    model="llama-3.3-70b-versatile",            # see Best Models table below
    messages=[{"role": "user", "content": "Hello!"}],
)
print(response.choices[0].message.content)
# Groq free tier: 30 RPM, 14,400 RPD — generous for personal use

Codex CLI

export OPENAI_BASE_URL="https://api.groq.com/openai/v1"
export OPENAI_API_KEY="your-groq-key"          # get at console.groq.com/keys
codex --model "llama-3.3-70b-versatile"

Cursor

Settings → Models → Add Model
  Model name: llama-3.3-70b-versatile
  Base URL: https://api.groq.com/openai/v1
  API key: your-groq-key                       # get at console.groq.com/keys

Claude Code

# Claude Code needs an Anthropic-compatible API — use OpenRouter
export ANTHROPIC_BASE_URL="https://openrouter.ai/api"
export ANTHROPIC_AUTH_TOKEN="sk-or-v1-your-key"  # openrouter.ai/keys
export ANTHROPIC_API_KEY=""                       # must be empty
# Note: OpenRouter Anthropic models need $10 top-up (one-time)

Contributing

We welcome contributions!

• Add a missing free model — Open an issue or submit a PR

Criteria for inclusion

A model belongs in this list if:

1. The provider explicitly offers a free tier (not just a trial credit)
2. The API is publicly accessible (no waitlist, closed beta, or reverse-engineering)
3. For trial credits: clearly labeled and minimum $1 credit value
