AI Playground
Compare every model, side-by-side.
Tune prompts across models in real time. Stream responses, compare cost and latency, then export production-ready AI Toolkit code.
Explain serverless functions in one paragraph.
A serverless function runs your code on demand without you managing servers. The platform provisions compute per request, scales to zero, and bills only for execution time and resources used. You deploy code, the platform handles infrastructure, and cold starts are the main trade-off for latency-sensitive workloads.
Serverless functions execute a single unit of logic in response to events, abstracting away the server entirely. The provider allocates resources purely per invocation — scaling up, down, and to zero automatically. You pay for what you use, and idle capacity costs nothing.
Features
Everything you need to pick the right model
Compare models side-by-side
Run the same prompt across different models in one view and pick the winner for your use case.
Real-time streaming
Watch tokens arrive as they are generated, so you can feel latency and tone before you ship.
Code generation & editing
Generate, explain, and refactor code with models tuned for the task, then export the result.
Prompt library
Start from pre-built examples for creative writing, analysis, translation, and more.
Export as AI Toolkit code
Tune a prompt and model in the playground, then generate ready-to-run AI Toolkit code.
And more, on Studio

Sample prompts
Start from a question, not a blank box
Pre-built examples cover the everyday tasks you will tune and compare in the playground.
“Write a short launch email announcing the new AI Toolkit playground.”
“Write a TypeScript function that fetches a URL with retries and exponential backoff.”
“Write a haiku about distributed databases.”
“Translate 'The stream has begun.' into Japanese, Spanish, and French.”
