Different models fit different jobs
Fast models are useful for simple classification and drafting. Strong reasoning models are better for complex analysis. Coding models help with software tasks. Multimodal models can work with images or documents.
- Simple tasks need speed.
- Complex tasks need reasoning.
- Media tasks need multimodal support.
Tradeoffs matter
Model choice affects response time, cost, quality, and reliability. A workflow should not always use the largest model if a smaller one can do the task well.
- Measure latency.
- Track token usage.
- Review quality samples.
Design a fallback
When a model is slow, unavailable, or too expensive for a task, use a backup model or send the task to human review.
- Fallback model
- Retry rule
- Human review path
