Stop Paying for AI: 100+ Premium Models You Can Use for Free

You are paying for AI you don’t need to pay for.

$20/month for ChatGPT. $20/month for Claude. $20/month for Cursor. $20/month for Perplexity.

$80/month to access models you could be running for free.

I spent 3 days mapping every legitimate free tier, free API, free credit, and free self-hosted model that exists right now.

Here is the complete map.

No credit card. No trial traps. No expiring free tier that bills you at 2am.

Save this. It will save you hundreds per year.

First — understand the two types of “free”

There are two completely different things people call “free AI.”

Type 1: Someone else runs it, you call it.

Google, Groq, Mistral, OpenRouter hand you an API key at zero cost. You get rate limits. You get real frontier models. You give up your prompts — most free tiers train on what you send.

Type 2: You download the weights and run it yourself.

Fully private. Nothing leaves your machine. You pay in electricity and VRAM instead of data or dollars.

These are not variations on a theme. They are opposites.

Choose based on what matters more to you: convenience or privacy.

The master list of free hosted APIs

These give you a real API key. No credit card. No 24-hour trial trap. Real models. Real rate limits. Real forever.

1. Google AI Studio

The best free access to a frontier model that exists right now.

→ ~1,500 requests/day on Gemini Flash. Resets daily.
→ 1M context window
→ Handles images and PDFs
→ Zero credit card. Zero expiry.

Go to: aistudio.google.com

Important: free-tier prompts may train Google’s models. Keep sensitive data off.

2. Groq

Fastest free inference alive.

300+ tokens per second on open-weight models. Llama, Qwen, Kimi — all running on custom LPU hardware.

→ ~30 req/min, 1,000/day on a 70B model
→ Clear no-training policy
→ OpenAI-compatible endpoint

You swap one base URL and your existing tools work instantly.

Go to: console.groq.com

3. Mistral (La Plateforme)

1 billion free tokens on signup.

→ Mistral Large 3 (competes with Claude Opus 4.7)
→ Codestral (beats GPT-5.5 on coding benchmarks)
→ Mistral Medium 3.5
→ Pixtral Large (vision)
→ 256K context windows
→ OpenAI-compatible

Setup:

# Step 1: Sign up at console.mistral.ai (no card)

  -H "Authorization: Bearer YOUR_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "mistral-small-latest",
    "messages": [{"role": "user", "content": "Hi"}]
  }'
# Step 4: Swap base URL in any tool
# Replace: https://api.openai.com/v1
# With:    https://api.mistral.ai/v1

Important: the free Experiment tier requires opting into training.

Go to Settings → Data Training → disable if you want privacy.

4. OpenRouter

One API key. 25+ permanently free models.

Filter with the :free suffix in any model name. No credit card. No expiry.

The hidden free credits most people miss

These are not permanent free tiers. They are one-time or promo credits that are large enough to matter.

AWS Bedrock: $200 free credits

Every new AWS account gets $200 in free credits.

You can use them on: → Claude Opus 4.8 → Claude Opus 4.7 → Claude Sonnet 4.6 → Claude Haiku 4.5

One router to rule them all: FreeLLMAPI

16 free providers. ~1.7 billion tokens per month. One endpoint.

FreeLLMAPI is an open-source self-hosted proxy that:

→ Stacks free tiers from Google, Groq, Cerebras, Mistral, OpenRouter, GitHub, Cloudflare, HuggingFace, and 8 more
→ Auto-routes to whichever provider isn’t rate-limited
→ Falls over automatically on 429s
→ Tracks per-key usage so you stay under every cap
→ OpenAI-compatible AND Anthropic-compatible

One base URL. Your existing tools work instantly.

from openai import OpenAI
client = OpenAI(
    base_url="http://localhost:3001/v1",
    api_key="freellmapi-your-unified-key",
)
# Auto-picks the best available free model
resp = client.chat.completions.create(
    model="auto",
    messages=[{"role": "user", "content": "What is RAG?"}],
)
print(resp.choices[0].message.content)
print("Routed via:", resp.headers.get("x-routed-via"))

For Claude Code specifically:

export ANTHROPIC_BASE_URL=http://localhost:3001
export ANTHROPIC_AUTH_TOKEN=freellmapi-your-unified-key
claude
# Now Claude Code routes through your free pool
Docker setup (one command):
bash
curl -fsSL https://freellmapi.co/install.sh | bash
# Opens at http://localhost:3001
# Add your provider keys
# Start routing

Go to: github.com/tashfeenahmed/freellmapi

Self-hosting: run models on your own machine

No API key needed. No rate limits. Fully private.

You just need RAM.

How much RAM do you need?

Rule: ~0.6 GB of RAM per billion parameters (at standard 4-bit quantization).

The easiest path: Ollama

# Install (Mac/Linux/Windows)
curl -fsSL https://ollama.com/install.sh | sh
# Run any model (downloads automatically)
ollama run qwen3:8b          # 5.5GB, great all-rounder
ollama run llama3.3:70b      # 40GB, near-frontier quality
ollama run mistral:7b        # 5GB, fast and capable
ollama run deepseek-r1:14b   # 9GB, strong reasoning
ollama run phi4:14b          # 9GB, punchy Microsoft model
# It auto-serves an OpenAI-compatible API at:
# http://localhost:11434/v1
# Plug into any tool immediately

The 20 best open-weight models to self-host

Sorted by what actually matters: license and hardware.

Truly free to use commercially (Apache 2.0 / MIT):

→ Qwen3 (Alibaba) — most versatile. 0.6B to 200B+. Apache 2.0.
→ DeepSeek-R1 (DeepSeek) — reasoning-heavy. MIT. Distills from 7B to 70B. → GLM (Zhipu) — MIT. Leads coding benchmarks at the large end.
→ gpt-oss (OpenAI) — Apache 2.0. Their open-weight family. 20B sweet spot. → Mistral / Devstral — Apache 2.0. Devstral for coding agents specifically.
→ Phi-4 (Microsoft) — MIT. Small but punchy. Phi-4-mini runs on any laptop. → OLMo (Allen AI) — Apache 2.0. One of the only truly open-source models (weights + training data + code, all public).
→ Granite (IBM) — Apache 2.0. Enterprise and RAG focused.

Open-weight with some conditions:

→ Llama 3.x (Meta) — open-weight but not truly open-source. 700M MAU cap (rarely relevant). Best: 8B (entry) to 70B (power).
→ Gemma 4 (Google) — license restricts using it to train competing models. 12B fits in 16GB. Good vision support.
→ Falcon-H1 (UAE) — 256K context. Royalty kicks in above $1M revenue.
→ Command R (Cohere) — non-commercial only. Fine for personal use.

Big ones that need datacenter hardware:

→ Kimi K2 (Moonshot) — 1T params. Genuinely frontier coding. Needs 550GB+.
→ MiniMax M3 — multimodal, 1M context. Datacenter only.
→ DeepSeek V4/R1 (full) — 671B MoE. ~370GB. Not for home use.

The hidden cost of “free” hosted tiers

Read this before using any free hosted API in production.

Most free tiers train on your prompts.

That means: your code, your business logic, your user data — all potentially in someone’s next training run.

The ones with explicit no-training policies:

→ Groq: clear no-training policy
→ Cerebras: explicit no-training
→ GitHub Models: scoped to development use
→ Self-hosted: 100% private by definition

The ones you should keep sensitive data off:

→ Google AI Studio (free tier may train)
→ Mistral Experiment tier (opt-in to training required)
→ HuggingFace Inference (standard T&C)

Rule: if the prompt contains client data, credentials, or anything you wouldn’t want in a training dataset — self-host or pay for a privacy-first tier.

Start in 5 minutes

Pick the one that fits your situation:

“I just want to try frontier models with zero setup”
→ Go to aistudio.google.com . Sign in with Google. Done.

“I need the fastest possible inference for an agent”
→ Groq.console.groq.com . API key in 2 minutes.

“I want Claude for free”
→ AWS Bedrock. $200 credits. Follow the setup above.

“I want 100+ models with one key”
→ NVIDIA API.build.nvidia.com. Phone verify, no card.

“I need privacy. Nothing leaves my machine.”
→ curl -fsSL https://ollama.com/install.sh | sh → ollama run qwen3:8b→ Done. Fully local. Fully private.

“I want everything stacked automatically”
→ FreeLLMAPI. One Docker command. 16 providers. 1.7B tokens/month.

The gap between what people pay for AI and what AI actually costs to access is growing every month.

$80/month was reasonable when this was all locked up.

It is not locked up anymore.
