Anthropic API Claude 4 Sonnet/Haiku, 200K context, vision Haiku 3.5 is cheapest; Sonnet 4 strongest on free trial
Hugging Face Inference Endpoints Host any open model on dedicated GPU instances Free serverless inference for popular models; paid for dedicated
Together AI 200+ model marketplace; fine-tuning API Best platform to experiment with obscure/new models
Replicate Run any model with one line of Python Pay per prediction; very low cost for occasional use
Modal Serverless GPU compute for custom model deployments Free $30/mo credits; ideal for running fine-tuned models

Updated Code Examples

Groq API (Recommended)
from groq import Groq

client = Groq(api_key="your-api-key")
response = client.chat.completions.create(
    model="llama-3.3-70b-versatile",
    messages=[{"role": "user", "content": "Explain quantization"}]
)
print(response.choices[0].message.content)

Note: "llama-3-8b-instant" is deprecated — use "llama-3.3-70b-versatile" or "qwen-qwq-32b" for reasoning.

Google Gemini API (Free, No CC)
import google.generativeai as genai

genai.configure(api_key="your-api-key") # from aistudio.google.com
model = genai.GenerativeModel("gemini-2.5-flash")
response = model.generate_content("Explain transformer architecture")
print(response.text)
OpenRouter (One Key, All Models)
from openai import OpenAI

client = OpenAI(
    base_url="https://openrouter.ai/api/v1",
    api_key="your-openrouter-key"
)
response = client.chat.completions.create(
    model="meta-llama/llama-4-scout:free", # free model flag
    messages=[{"role": "user", "content": "Write a Fibonacci function"}]
)

50 Additional Facts & Tips

API Mechanics
  • All major providers use OpenAI chat completions format — switching providers often just means changing base_url
  • Groq rate limits apply at org level — multiple API keys do NOT bypass limits
  • Google AI Studio keys share quota at project level — multiple keys share one bucket
  • Cached tokens on Groq do NOT count toward rate limits — use prompt caching for repeated system prompts
  • Together AI offers fine-tuning API access — train custom adapters on their infrastructure
  • OpenRouter lets you set a budget cap per request — prevents runaway costs while experimenting
Platforms Worth Knowing
  • Cerebras uses WSE-3 chip (not GPU) — delivers 2,000+ tokens/sec, 7× faster than best GPU inference
  • Cloudflare Workers AI runs inference at CDN edge — add AI to a web app with zero infrastructure
  • Modal gives $30/month free serverless GPU — ideal for running fine-tuned models
  • Kaggle gives 30h/week GPU (T4 x2 or P100) — better than Colab for long training runs
  • Hugging Face Spaces lets you deploy Gradio/Streamlit apps free — shareable URL, no server needed
  • Mistral Nemo (12B) available free via Mistral API — strong multilingual support including Arabic/French
Building Real Projects for Free
  • Full free chatbot: Groq API + Streamlit + Hugging Face Spaces = deployed at $0
  • Full free RAG: Gemini API + Cohere Embed 3 + ChromaDB = document Q&A for free
  • Free image gen: Cloudflare Workers AI includes Flux + Stable Diffusion — 10K free runs/day
  • Free speech-to-text: Groq runs Whisper V3 Large at 315× realtime — free tier includes transcription
  • Free code sandbox: E2B (e2b.dev) gives free sandboxed Python execution — combine with Groq
  • Use OpenRouter free models for dev; switch to paid only for final demo — no code changes needed
Practical Tips
  • Store API keys in environment variables — use python-dotenv; never hardcode
  • Use .env files with .gitignore — GitHub secret scanning now alerts on exposed keys
  • Rate limit your requests in dev — add time.sleep(1) between calls to stay within free tier
  • Test with short prompts while building — long prompts eat token budgets fast
  • Use streaming responses (stream=True) for UI demos — shows output as it generates
  • Bookmark cheahjs/free-llm-api-resources on GitHub — community-maintained, always updated
