Strategy: Tiered Enterprise Routing
The smartest enterprise approach is to route tasks by complexity and compliance requirements, using budget models for routine work and premium models for high-stakes decisions.
This tiered approach saves 87% compared to using a premium model for everything. The key insight: most enterprise API calls are routine lookups, formatting, or simple classification that don't need premium intelligence.
Enterprise Compliance Guide
- SOC 2 Type II: OpenAI, Anthropic, and Google all maintain SOC 2 Type II certification. Required for most enterprise procurement.
- HIPAA: Google Cloud Vertex AI and AWS Bedrock offer BAA agreements for healthcare data. Azure OpenAI also supports HIPAA workloads.
- Data Residency: Google and Azure offer regional data storage (EU, US, APAC). OpenAI offers data processing agreements but limited regional controls.
- On-Premise: For air-gapped environments, consider open-source models (Llama, Mistral) via vLLM or Ollama. No API costs, but infrastructure overhead.
- Audit Logging: All Big 3 providers offer API call logging for compliance audits. Budget providers (DeepSeek, Mistral) have limited audit capabilities.
- Data Retention: OpenAI Enterprise and Anthropic offer zero data retention for API calls. Google offers data deletion APIs. Budget providers may retain prompts for training.
