## When to use advanced LLM configuration
|
|
|
|
- You need predictable quality, latency, and cost control.
|
|
- You need model routing by task type.
|
|
|
|
## Core decisions
|
|
|
|
| Decision | Choose this when |
|
|
|---|---|
|
|
| Single model | Small systems with uniform task profile |
|
|
| Routed models | Mixed workloads with different quality/cost needs |
|
|
| Structured output | Automation pipelines and strict parsing needs |
|
