You Don’t Need OpenAI to Build Great AI: 5 Free Platforms That Prove It

If you’re learning generative AI and think you need a big budget or OpenAI’s API to get started — think again. There are free tools out there that not only let you build cool projects but also teach you the real-world skills hiring teams are actually looking for.

Here are five platforms I’ve explored that let you experiment, build, and ship AI projects — all for free.

1. Together AI

Best for: Model experimentation and multi-LLM projects
Together AI gives you access to models like LLaMA 3, Mistral, DeepSeek, and Mixtral — all through a simple API. It’s fast, reliable, and has a generous free tier with daily token limits.

Why I like it: It’s perfect for trying different models and comparing outputs. Great for building chatbots or RAG systems.

2. Groq Cloud

Best for: Speed and low-latency apps
Groq runs LLMs like LLaMA 3 on custom-built chips (LPUs), and it’s insanely fast. Think sub-100ms response times. Perfect for apps where speed matters — like real-time chat or voice assistants.

Why I like it: It feels like the future. You can build a super-fast chatbot with no credit card and no waiting.

3. Fireworks AI

Best for: Code tools and custom workflows
Fireworks hosts models like DeepSeek Coder, LLaMA 3, Claude, and more. It’s dev-friendly, well-documented, and supports things like streaming responses and fine-tuning.

Why I like it: The mix of open and closed models makes it a flexible platform for testing coding assistants, summarizers, or agent-style tools.

4. Hugging Face

Best for: Building and showcasing projects
More than just a model hub, Hugging Face lets you build Spaces (mini apps), explore datasets, and deploy your own models — even with free CPU or trial GPU time.

Why I like it: It’s where the AI community lives. And publishing on HF can help your work get noticed.

5. Ollama (Local Runtime)

Best for: Learning how LLMs run under the hood
Ollama lets you download and run LLMs locally on your own machine. If you're on Mac or Linux (or use WSL), it's a great way to tinker with models like Mixtral, Phi-3, or LLaMA without cloud limits.

Why I like it: It helps you understand what happens behind the API. Plus, no usage caps once it’s running.

Final Thoughts

You don’t need OpenAI or a corporate budget to learn and build with GenAI. These five platforms give you real power, for free. If you’re building a portfolio or preparing for AI job interviews, experimenting with these tools will give you a serious edge — and maybe even something worth shipping.
