Why use more than one model
Section titled “Why use more than one model”No single model is optimal at everything. They differ across:
| Dimension | The gap |
|---|---|
| Reasoning depth | Huge difference on complex logic, math, architecture |
| Speed | Light models feel much faster on simple tasks |
| Cost | A top model can cost 10x+ a light one |
| Specialties | Some excel at code, some at prose, some at multimodal |
People who allocate well do ten times the work on the same budget.
Allocation strategy
Section titled “Allocation strategy”By complexity
Section titled “By complexity”| Task | Pick |
|---|---|
| Bulk formatting, simple extraction, translation | Light model (fast, cheap) |
| Routine code and docs | Main model |
| Architecture, hard debugging, key decisions | Reasoning-enhanced model |
By stage
Section titled “By stage”Split one complex job across models:
- Exploration (read code, gather sources) → cheap model, high volume is fine
- Design → strong model; a mistake here poisons everything downstream
- Bulk execution → cheap model following an approved plan
- Review → strong model as the final gate
Local vs cloud
Section titled “Local vs cloud”Local advantages
- Data never leaves your machine
- No per-call cost
- Works offline
Local limits
- Hardware bound (RAM is usually the constraint)
- Some custom architectures need a purpose-built runtime; generic frameworks won’t load them
- Fanless machines throttle under sustained load
- Usually weaker than top cloud models
Practical split: sensitive data and simple tasks locally; complex tasks in the cloud.
Aggregator setups
Section titled “Aggregator setups”If you hold multiple subscriptions or API keys, an aggregator gives you:
- One entry point across models
- Unified usage logs
- Easy A/B comparison
Setup essentials: configure authentication, configure your local proxy if you’re behind one, and confirm which models your subscription tier actually unlocks.
Cost control
Section titled “Cost control”Use cheap models for grunt work Processing 500 files doesn’t need the flagship.
Control context length Long sessions are expensive. Clear irrelevant context; start new sessions per task.
Cache conclusions Store exploration results in project memory instead of re-reading the codebase every time.
Set budget caps Especially for automation — one runaway loop can burn through a budget fast.
One caution
Section titled “One caution”Multi-model collaboration assumes you can judge output quality. If you can’t tell which result is better, stacking models won’t help. Build domain knowledge first, or use models to cross-check each other.
