The Speed Challenge
LLM councils naturally take longer than single-model queries. Here's how to minimize latency while preserving the benefits of multi-model AI.
Latency Sources
Sequential Processing
If models run one after another, times add up.
Model Response Time
Different models have different speeds:
- Gemini Flash: Very fast
- GPT-4o-mini: Fast
- Claude 3.5 Sonnet: Moderate
- Large models: Slower
Council Deliberation
Debate rounds add significant time.
Synthesis
Final combination takes additional processing.
Optimization Strategies
1. Parallel Execution
Always run fan-out models in parallel:
- All models start simultaneously
- Total time = slowest model, not sum
- 5x faster than sequential
2. Model Selection for Speed
Choose faster models when latency matters:
- Gemini 1.5 Flash (fastest)
- GPT-4o-mini (fast)
- Claude Haiku (fast)
- Nanbeige (efficient)
3. Skip Unnecessary Steps
For simple queries:
- Skip peer review
- Skip debate rounds
- Direct synthesis
4. Streaming Responses
Stream synthesis as it generates:
- User sees progress
- Perceived latency lower
- Better experience
5. Early Termination
If models agree strongly:
- Skip additional deliberation
- Return early consensus
- Save time
6. Predictive Routing
Use query patterns to predict:
- Which models will be needed
- Whether full council is necessary
- Optimal processing path
