Google AI Studio (Gemini)
★ 4/5 · Inference Platform
Google's free browser workspace where developers prototype prompts with Gemini models, tune parameters, and export working code plus an API key for their apps.
Pros
- Free tier requires no credit card with access to Gemini 3.5 Flash, 2.0 Flash and 1.5 Pro models
- browser-based interface with syntax highlighting, parameter tuning UI, and prompt templates for rapid prototyping
- multimodal input supporting text, images, audio and video files
Cons
- Rate limits (10-30 requests/minute) restrict testing at production scale even on free tier
- Google may retain prompts for model improvement on free tier creating data retention concerns
- no version control or collaborative editing features for team-based development
Cost
Free tier with rate limits; API usage billed per model, e.g. Gemini 2.5 Flash ~$0.30/M input tokens and $2.50/M output tokens; higher for Pro-tier models (unverified exact current rate card)
Verdict
Ideal for solo developers and researchers needing immediate access to Gemini models for prototyping without setup friction.
