How to Choose the Best AI Model for Your Business
With dozens of AI models available, choosing the right one can be overwhelming. This guide helps you match your business needs to the best model options.
Key Decision Factors
Use Case Complexity
Simple tasks (summarization, translation) can use smaller, cheaper models. Complex reasoning needs frontier models.
Budget Constraints
Costs range from $0.10 to $60 per million tokens. Volume matters—high-usage apps need cost optimization.
Data Privacy Requirements
Sensitive data may require EU hosting, on-premise deployment, or models that don't train on your data.
Speed Requirements
Real-time applications need fast inference. Batch processing can tolerate slower, more capable models.
