Model Comparison
One request. Multiple models. A clear decision -- in seconds instead of weeks.
Three comparison dimensions
Answer quality
See side by side which model delivers the best tone, depth and fewest errors.
Response time
Time until the complete answer -- per model, per request.
Budget usage
Each model's price as a percentage of your monthly budget.
How model comparison works
Four steps from opening to result -- both models in parallel.
- 1
Open Model Comparison
Open 'Model Comparison' in the menu. Two model slots (A and B) sit side by side.
- 2
Pick two models
Choose one model each for slot A and slot B from the EU models enabled for you.
- 3
Enter the request once
One prompt -- both models receive the same input.
- 4
Two answers streaming in parallel
Answers appear token by token side by side. The response time is shown per model.
When is a model comparison worthwhile?
Four concrete use cases where side-by-side comparison saves hours of research.
Picking a model for a team
Before committing 'we use model X for marketing copy' test the candidates head to head instead of guessing.
Quality assessment of new models
When a new model launches (e.g. Claude Opus 5), pit it directly against the predecessor and rivals.
Cost optimisation
Check if a cheaper model (e.g. Claude Haiku) suffices for your tasks.
Troubleshooting bad answers
Is the default model having a bad day? Comparison instantly shows whether the issue is the model or the prompt.
Benefits
Frequently asked questions on model comparison
Answers on slots, usage, models and logging.
How many AI models can I compare in parallel?+
Two models simultaneously (A/B). Answers are streamed in parallel side by side -- each with its response time.
Which models are available for comparison?+
All 100+ EU-hosted models of the platform: Claude (Sonnet, Opus, Haiku), GPT family, Google Gemini, Mistral, Meta Llama, Cohere, DeepSeek, xAI Grok. Freely selectable per slot.
Does a comparison cost more than a normal request?+
Yes -- each model bills its own tokens. A comparison uses roughly as much as two single requests, depending on the model. Each model's price is shown as a percentage of your monthly budget.
When is a model comparison worthwhile?+
For important decisions: 'Which model do we set as default?', 'Is the more expensive model worth it?', for quality audits or when a new model launches.
How long does a comparison of two models take?+
About as long as the slower model. Since both run in parallel there is no sequential bottleneck -- typical response time 2 to 15 seconds depending on task complexity.
Are comparisons logged?+
Yes. Each model request of a comparison is logged in your company's request audit: model, time and usage -- without prompt or answer text.
Are the requests truly sent identically to both models?+
Yes -- both models receive the same prompt and the same system message.
