Every AI project starts with the same wall: an API key that costs money. These 8 paths get you real, working access for $0.

## Free API Access Is Real, But Read the Fine Print Free tiers exist at nearly every major provider in 2026. The catch is always the same: rate limits, expiration, and restrictions on commercial use. For prototyping, learning, and personal projects, they are plenty. ## The 8 Paths 1. **Google AI Studio (Gemini API)** - the most generous free tier in the industry: thousands of free requests per day on the flash models with a Google account. Great for learning and prototyping. 2. **Groq** - fast open-model inference (Llama, Mixtral family) with a free tier designed for developers. Insanely fast tokens-per-second. 3. **OpenRouter** - one key, dozens of models including open source ones; free models on the platform cost $0 per token (rate-limited). Good for comparing models cheaply. 4. **Cloudflare Workers AI** - a free daily allocation of open model inference (Llama, Mistral, embeddings) with generous limits for hobby projects. 5. **Hugging Face Inference API** - free monthly credits for open models; good for experimenting with the whole open ecosystem. 6. **Local models (Ollama, 178,131 stars)** - the true $0 option: no key at all, runs offline. Free forever, private, unlimited - you just need the hardware. 7. **LocalAI (48,350 stars)** - OpenAI-compatible local server, so your existing OpenAI SDK code runs against local models with zero changes. The free API that mimics the paid one. 8. **Student / startup programs** - GitHub Student Pack and cloud startup credits regularly include AI API credits. Check eligibility before buying anything. ## What Free Means in Practice - **Rate limits**: typically 10-60 requests per minute on free tiers. Fine for testing, not for a public product. - **Data usage**: free tiers may train on your data - check current terms before sending sensitive content. - **Expiration**: some free credits expire in 30-90 days. ## The Smart Setup Use a local model for dev (path 6), free tiers for demos (1-3), and only reach for paid APIs when you have users. This path keeps your project cost at $0 until it earns money.
