The Bottom Line: FreeLLM Eliminates AI API Costs Entirely

What Is FreeLLM.net? — The "Master Catalog" of Free LLM APIs

freellm.net is a website that lets you browse, compare, and configure free LLM APIs available as of 2026.

The companion GitHub repository awesome-freellm-apis (open-free-llm-api/awesome-freellm-apis) provides the same data in machine-readable format, updated automatically every day.

Why Do You Need This?

Traditionally, finding free LLM APIs came with these problems:

• You had to visit dozens of individual provider websites
• Services labeled "free" still required credit card registration and eventually charged you
• Rate limits and context sizes varied wildly, making comparisons difficult
• Outdated information meant broken APIs were mixed in

freellm.net solves all of these in one place.

Free Provider Directory (28 Companies)

Below is a curated list of providers that are genuinely free to use. Those that advertise "free" but still require a credit card are noted separately.

No Credit Card Required

Phone Verification or Account Registration Required (Effectively Free)

Spotlight: OpenRouter (Renewable Credits)

OpenRouter is a bit unique — with the free tier + a one-time $10 charge, you get up to 1,000 free requests per day. Since it has an Anthropic-compatible API endpoint, this is the go-to choice if you want to run Claude Code for free.

You get 28 free models and support for up to 1M context.

Free Model Rankings — Top 10

The top 10 free models currently available, scored by freellm.net:

My personal standout is MiniMax M3 (Score 95). With 1M context, image support, and 40 RPM, the specs are hard to believe for a free tier. DeepSeek V4 Pro is also impressive at 1M context and score 86.

Get Started with Free LLM APIs in 3 Steps

Step 1: Pick a Provider

For beginners, Groq is the strongest recommendation.

• Sign up with just an email address (no credit card)
• llama-3.3-70b-versatile at 30 RPM for free
• 14 models ready to use immediately
• Time required: 2 minutes

Sign up here → console.groq.com/keys

Step 2: Get Your API Key

After creating an account on each provider's site, generate an API key. For most providers, the process is:

1. Register an account (email or Google account)
2. Navigate to the API Keys / Tokens page
3. Click "Create API Key"
4. Copy and save the generated key

Never share your API key publicly. Accidentally committing it to GitHub can lead to unauthorized usage and unexpected charges.

Step 3: Configure Your Tools

Use the API key you obtained to set up your AI coding tools.

Setup Guides by AI Tool

Using with Cursor

Setting up a free LLM API in Cursor is extremely straightforward.

Steps:

1. Open Cursor Settings (⚙️)
2. Click Models → Add Model
3. Enter the following information

Model name: llama-3.3-70b-versatile
Override OpenAI Base URL: https://api.groq.com/openai/v1
OpenAI API Key: <your Groq API key>

4. Click "Verify" to confirm the connection
5. Enable the model

For providers other than Groq, the same steps work as long as they have an OpenAI-compatible endpoint.

Using with Codex CLI

# When using Groq
export OPENAI_BASE_URL="https://api.groq.com/openai/v1"
export OPENAI_API_KEY="<your Groq API key>"

# Or NVIDIA NIM
export OPENAI_BASE_URL="https://integrate.api.nvidia.com/v1"
export OPENAI_API_KEY="<your NVIDIA API key>"

# Launch Codex
codex --model "llama-3.3-70b-versatile"

Using with Claude Code

Claude Code requires an Anthropic-compatible API. OpenRouter is the only realistic option here.

# Using Claude Code via OpenRouter
export OPENROUTER_API_KEY="<your OpenRouter API key>"
export ANTHROPIC_BASE_URL="https://openrouter.ai/api"
export ANTHROPIC_AUTH_TOKEN="$OPENROUTER_API_KEY"
export ANTHROPIC_API_KEY=""  # Explicitly empty — important

# Launch
claude

Note: Using Anthropic models on OpenRouter requires a one-time $10 charge. After that, you can use up to 1,000 free requests per day.

Using with Hermes Agent

With recent updates, Hermes Agent also supports custom API endpoints. Add the following to ~/.hermes/config.yaml:

# Example using Groq
provider: openrouter  # Specify an OpenAI-compatible provider
model: groq/llama-3.3-70b-versatile
api_key: <your Groq API key>
base_url: https://api.groq.com/openai/v1

Alternatively, use freellm.net's Config Generator to auto-generate setup code for each tool. → freellm.net/config/

Caveats & Downsides (Honest Assessment)

When using free APIs, you need to understand the following:

1. Rate Limits Are Strict

Free tiers naturally come with rate limits. For example, Groq gives you 30 RPM (30 requests per minute). Not suitable for bulk code generation or batch processing.

2. No Availability Guarantee (SLA)

Free APIs are best-effort operations. They may suddenly go down or become slow. Absolutely not suitable for production environments.

3. Model Availability Changes Frequently

Daily data updates mean things are constantly shifting. A model that was free this week might go paid next week.

4. Don't Send Confidential Data

Many free providers may use transmitted data for model training. Never send company confidential or personal information to free APIs.

5. Chinese Providers Deserve Extra Caution

Chinese providers like Z AI (Zhipu AI) or Alibaba Cloud may handle data differently from Japanese or international regulations. Check the terms of service before use.

---

Advanced: Bundling Multiple Free APIs Together

To work around free API rate limits, bundling multiple providers is highly effective.

For example, combining these services enables practical development:

• Groq (LLaMA 3.3 70B / 30 RPM) — Primary code generation
• NVIDIA NIM (75 models / 40 RPM) — Backup & image recognition
• Google Gemini (5 models / 15 RPM) — Long-form processing & research
• Cloudflare Workers AI (13 models / unlimited) — Batch processing

Plus, freellm.net's Config Generator auto-generates optimal setup code for each tool, so switching between multiple providers is just one click away.

Frequently Asked Questions

Q: What's the difference between freellm.net and awesome-freellm-apis?

freellm.net is the website version (GUI for browsing, comparing, and generating configs). awesome-freellm-apis is the GitHub repository version (machine-readable data, auto-updating). The data is identical and synced daily.

Q: Can I use these free APIs for commercial purposes?

It depends on each provider's terms of service. Groq, NVIDIA NIM, and Google Gemini free tiers often permit commercial use, but always verify with each provider's terms.

Q: What's the single best free provider?

For beginners: Groq. No credit card, 30 RPM, fast inference — ideal as an entry point to free APIs. If you want more advanced models, go with NVIDIA NIM (phone verification only, 75 models).

Q: What should I do when I hit a rate limit?

Switch to a different provider or space out your requests. Rotating through multiple providers is the most practical approach.

Q: Can I combine it with Cursor's free trial?

Yes. Pair Cursor's free trial (2-week Pro) with free LLM APIs, and you have an essentially cost-free AI coding environment.

Q: How often is the data updated?

freellm.net data is updated daily. 53 models are verified by actually hitting their APIs, and those show a "Verified" status.

Q: Are Chinese providers (Zhipu / Alibaba) safe?

Follow each company's standard practices for API key management. Regarding data handling, be aware that differences exist between Japanese law and Chinese law. Avoid sending confidential data.

Q: How long is this information valid?

As of June 26, 2026. Free tiers can change without notice. Always check freellm.net directly for the latest information.
