Detailed Comparison

A side-by-side analysis of key factors to help you make the right choice.

Factor
AI InferenceRecommended
AI TrainingWinner
Purpose
Applying a trained model to generate responses to new inputs in production
Developing a new model by learning patterns from large datasets
Compute Cost
Low: $0.001-$0.10 per request via API; accessible to any business
Extreme: GPT-4 training estimated at $50-100 million; only for well-funded labs
Time to Value
Milliseconds to seconds per request; immediate value delivery
Weeks to months for large frontier models before any output is available
Hardware Requirements
1-8 GPUs for smaller models; larger models available via API with no infra
Thousands to tens of thousands of GPUs; extreme memory bandwidth required
Enterprise Relevance
Directly relevant — nearly all enterprises interact with AI through inference APIs
Only relevant for large tech companies and well-funded research labs
Scalability
Horizontally scalable by adding more inference servers; natural load balancing
Limited by gradient communication overhead in distributed training setups
Optimization Goals
Latency, throughput, cost per token, energy efficiency
Convergence speed, generalization, perplexity, downstream task performance
