Skip to main content Model Playground Every model on Runcrate has an interactive playground in the dashboard. Test models, experiment with parameters, and get auto-generated code — without writing any code yourself.
Accessing the Playground
Go to Dashboard → Models
Click on any model
The playground opens with the model ready to use
Playground Types The playground adapts to the model’s category:
Chat Playground For Chat, Code, Reasoning, and Vision models.
Real-time streaming — Responses appear token-by-tokenSystem prompt — Set the model’s behaviorMulti-turn conversation — Full conversation historyTemperature and max tokens — Adjustable via settings panelImage uploads — For vision-capable models, attach images to your messagesReasoning blocks — For reasoning models, thinking steps are shown in collapsible blocks
Image Playground For image generation models.
Prompt input — Describe the image you wantParameter controls — Aspect ratio, steps, guidance, seed, and model-specific settingsLive preview — Generated images display inlineReference images — Upload images for img2img, editing, and Kontext models
Video Playground For video generation models.
Prompt input — Describe the videoDuration selector — Choose from available durations (buttons or slider depending on model)Async status — Shows job status (queued → processing → completed)Video player — Watch the result directly in the browserDownload — Save the MP4
TTS Playground For text-to-speech models.
Text input — Enter the text to speakVoice selector — Choose from available voice presetsAudio player — Listen to the result with streaming playback
ASR Playground For speech-to-text models.
File upload — Upload an audio file (MP3, WAV, etc.)Transcription output — View the transcribed textDuration and language — Shows detected language and audio duration
Auto-Generated Code Every playground shows a code panel with working examples in three languages:
curl — Direct HTTP requestPython — Using the OpenAI SDKJavaScript — Using the OpenAI SDK
The code updates automatically based on your selected model and parameters. Copy it directly into your application.
API Key The playground uses your project’s default API key. If you don’t have one yet, it’s created automatically when you first open a model.
