If you’re a developer navigating the ever-evolving world of large models and AI tooling, Google’s latest move is worth your attention. The company has rolled out Gemini 2.5 Pro Experimental, its most advanced model to date, and it’s available right now—even for free.

What Can You Get for Free?

Google’s Gemini API Free Tier offers a generous package, ideal for developers testing ideas, building prototypes, or simply experimenting with advanced AI models—without incurring costs.

1. Top-tier models for free:

1. Gemini 2.5 Pro Experimental: tuned for complex reasoning and coding tasks
2. Gemini 2.0 Flash: all-purpose with a massive 1M-token context window
3. Flash-Lite: lightweight and efficient for scalable workloads

2. Google AI Studio remains 100% free in all supported countries. No time limits. No hidden charges.

3. Text Embedding 004: Google’s latest embedding model is also part of the free offering.

4. Grounding with Google Search: Available for free up to 500 requests per day (RPD) across select models.

Free-tier usage may be used to train future models, while the paid tier ensures your data isn't used for training.

Benefits of Paid Tier

When you’re ready to scale or need production-level reliability, the paid tier unlocks key advantages:

1. Higher rate limits
2. Larger prompt sizes & context windows
3. Context caching (starting April 15, 2025)
4. Access to Imagen 3 for image generation

Grounding with Google Search: Up to 1,500 RPD for free, then $35/1K requests on compatible models.
