Playground
Chat with a model, or compare two models on the same prompt.
With a key in place, open the playground and start a chat. After the model replies, the turn shows:
- Time to first token (TTFT)
- Total seconds for the response
- Which model answered

Compare two models on the same prompt
You can also run the same prompt against two models and read both replies and both metric sets.
- Start a chat.
- Choose the two models to compare. In the sample walkthrough these were Gemma and Nemotron.
- Send the prompt.
- Read the two responses and the metrics under each one.
Example metrics from that comparison:
| Metric | Gemma | Nemotron |
|---|---|---|
| TTFT | 1.2 s | 1.2 s |
| Total time | 2.1 s | 1.9 s |
| Tokens | Shown per model | Shown per model |
| Cost | Shown per model | Shown per model |
Your numbers will differ. Both models show tokens, cost, TTFT, and total time for the same input.
