Free via Google AI Studio: roughly 250 requests/day, rate-limited, no credit card required. Daily quota resets at midnight Pacific. Google AI Pro adds $10/mo Cloud credit for more.
Gemini 2.5 Flash is Google's fast multimodal workhorse — a strong balance of speed, quality, and cost across text and images.
It's genuinely free via Google AI Studio: create an API key and you get a per-account daily quota (~250 requests/day at the time of writing), rate-limited, no credit card. Google sets the exact limits and they can change — check your AI Studio dashboard for live numbers. Google AI Pro subscribers also get $10/month in Cloud credits usable on the Gemini API.
Google AI Studio is the direct free route for Gemini Flash models. It provides browser-based key creation, recurring free-tier limits, and first-party Gemini API documentation.
Use this endpoint when you want Google's native Gemini API key and free quota, especially for multimodal prompts and fast model experiments.
Pick a model, paste your own free key, and run. Your key is sent once to call the provider and never stored on our servers.
