INTEGRATION

Drop-In Code Playbook (Python & Node.js)

Because these providers adhere to the official OpenAI REST API specification, you can swap them into your existing codebase simply by changing the baseURL and apiKey:

PYTHON OpenAI SDK Python Drop-In (Groq / Gemini / Cerebras) 
from openai import OpenAI

# Connect to Groq Cloud (Free Llama 3.3 70B @ 500 tokens/s)
client = OpenAI(
    base_url="https://api.groq.com/openai/v1",
    api_key="gsk_YOUR_FREE_GROQ_KEY"
)

response = client.chat.completions.create(
    model="llama-3.3-70b-versatile",
    messages=[
        {"role": "system", "content": "You are an expert growth engineer."},
        {"role": "user", "content": "Draft a high-converting cold email hook."}
    ]
)

print(response.choices[0].message.content)
NODE.JS JavaScript / TypeScript Drop-In 
import OpenAI from 'openai';

const client = new OpenAI({
  baseURL: 'https://api.cerebras.ai/v1',
  apiKey: process.env.CEREBRAS_API_KEY,
});

const response = await client.chat.completions.create({
  model: 'llama3.1-70b',
  messages: [{ role: 'user', content: 'Analyze this customer feedback.' }],
});

console.log(response.choices[0].message.content);
AUTOMATION

The Rate-Limit Bypass: Multi-Provider Fallback Router

The only downside of free tiers is requests-per-minute (RPM) limits. The solution is automated provider fallbacks. By deploying open-source LiteLLM, your application automatically routes requests to Cerebras, then Groq, then Sambanova if one provider encounters rate-limiting (HTTP 429):

CONFIG LiteLLM Proxy Config (Zero Downtime Fallback Chain) 
model_list:
  - model_name: free-fast-llm
    litellm_params:
      model: groq/llama-3.3-70b-versatile
      api_key: os.environ/GROQ_API_KEY
  - model_name: free-fast-llm
    litellm_params:
      model: cerebras/llama3.1-70b
      api_key: os.environ/CEREBRAS_API_KEY
  - model_name: free-fast-llm
    litellm_params:
      model: sambanova/Meta-Llama-3.3-70B-Instruct
      api_key: os.environ/SAMBANOVA_API_KEY

FAQ

Frequently Asked Questions About Free AI APIs

Do these 134+ AI APIs require a credit card or billing setup?

No. The providers cataloged in this directory offer permanent free developer tiers or generous trial allowances without requiring credit card details or automated renewal traps.

Are these free AI APIs compatible with the official OpenAI SDK?

Yes. Over 90% of the providers offer OpenAI-compatible endpoints. You simply update your client configuration with their baseURL and API key to use standard SDKs in Python, TypeScript, LangChain, and Cursor.

How can I avoid hitting rate limits when using free AI tiers?

By deploying a lightweight proxy router like LiteLLM or an automated round-robin fallback script, your requests seamlessly fail over to an alternate provider (e.g. Groq to Sambanova to Cerebras) whenever one hits a rate limit.

Which models can be accessed completely free of cost?

You can access state-of-the-art models including Llama 3.3 70B, Llama 3.1 8B, Google Gemini 2.0 Flash, Gemma 2 27B, DeepSeek R1, Mistral NeMo, and Qwen 2.5.
