# Batch Inference vs Real Time Inference

## Detailed Comparison

| Factor | Batch Inference | Real-Time Inference | Winner |
|--------|------|------|--------|
| Latency | High: minutes to hours; no immediate individual response | Low: milliseconds to seconds; immediate response for interactive use | Real-Time Inference |
| Cost per Token | 40-80% cheaper; providers offer ~50% batch discounts; ideal for volume | Standard API pricing; no batch discount; higher cost for same volume | Batch Inference |
| GPU Utilization | Very high: simultaneous processing of many requests maximizes hardware usage | Variable: must reserve capacity for spikes, often underutilized at low load | Batch Inference |
| Use Cases | Document processing, catalog generation, nightly pipelines, data enrichment | Chatbots, AI assistants, live translation, interactive recommendations | Tie |
| Scalability | Easy to scale: jobs queue without quality degradation, natural backpressure | Requires proactive capacity planning and often deliberate over-provisioning | Batch Inference |
| Implementation Complexity | Moderate: batch job management, status tracking, result retrieval required | Lower for simple requests; higher for scalable production systems with SLAs | Tie |

## Key Statistics

- **Batch inference is typically 40-80% cheaper than real-time inference** (2025)
- **Anthropic and OpenAI offer approximately 50% discounts on batch API requests** (2025)
- **At 1 million output tokens/day: batch saves $37.50 vs Opus real-time ($37.50 vs $75)** (2025)
- **Real-time inference typically requires 2-3x more server capacity for the same base load due to spike handling** (2025)
- **90% of enterprise AI workloads could be at least partially migrated to batch processing** (2025)
