Test in the Playground
The Playground is a built-in platform UI for trying models with no code.
Steps
- Sign in to the platform and open the Playground
- Pick a model at the top (e.g. the free
gemini-flash) - Choose a mode: Chat, Plan, or Agent (plan-only agent)
- Type a message, send it, and read the model's reply
What you can do
- See a token estimate for your message
- Save conversation history
- Upload files as context (text / code / PDF / image — see File upload)
- Export a conversation or plan as Markdown (Artifacts)
About credits
Playground calls are billed per model just like API calls (except free trial models). If you see an insufficient-balance message, check Balance & usage or ask an administrator to grant test credit.
