For sensitive business data, consider models with strong privacy guarantees. Anthropic's Claude and Microsoft's Azure OpenAI offer enterprise-grade data handling. Self-hosted open-weight models (DeepSeek, Llama) give you full data control.
Don't just compare per-token pricing. Factor in integration costs, training time, error rates (which affect rework), and scaling costs. A more expensive model that requires fewer retries can be cheaper overall.
Gemini integrates natively with Google Workspace. GPT models integrate with Microsoft 365 via Copilot. Claude integrates with Slack and development tools. Choose the model that fits your existing workflow.
For production business applications, uptime and reliability matter. OpenAI, Anthropic, and Google all offer enterprise SLAs. Open-source models require you to manage your own infrastructure reliability.
