Overview
Google Gemini 3 entered the market with a splash, challenging the dominance of existing large language models. Its launch coincided with a period of rapid AI improvements, making it an attractive option for users looking for a powerful yet affordable assistant.
Free Tier Modes: Fast and Thinking
The free tier offers two distinct modes:
- Fast – Ideal for quick, general queries. I never hit the limits while using this mode.
- Thinking – Designed for deeper research and complex topic breakdowns. The number of prompts varies with server demand, typically allowing 5‑10 thoughtful interactions per day.
How I Use Thinking Mode
Thinking mode became my go‑to for:
- Breaking down intricate subjects into digestible parts.
- Gathering surface‑level research before diving deeper.
- Saving the results and asking follow‑up questions over multiple sessions.
I often exhausted my daily quota, waited for the reset, and repeated the cycle. The ability to switch back to Fast mode for quick checks after a heavy thinking session made the workflow smooth.
When to Upgrade to Pro
The $19.99/month Google AI Pro tier unlocks unlimited Thinking prompts and additional features like Deep Research. I considered the upgrade when I needed:
- Consistent access to Thinking mode without daily limits.
- More advanced summarisation and data‑lookup capabilities.
- Long‑running reports that can take 10‑15 minutes to generate.
At the time of writing, the price felt reasonable for power users, but casual users may still find the free tier sufficient.
Pros and Cons
- Pros
- Two distinct modes cater to both quick answers and deep dives.
- Reasonable pricing for the Pro tier.
- Good summarisation of long documents.
- Cons
- Thinking prompts are limited on the free tier.
- Performance can vary with server load.
Final Verdict
Google Gemini 3 is an all‑rounder AI that balances speed and depth. The free tier provides enough functionality for most everyday tasks, while the Pro tier offers the flexibility needed for intensive research. If you’re looking for a cost‑effective LLM that adapts to your workflow, Gemini 3 is worth a try.
