How do enterprises evaluate LLM API costs for production workloads?

LLM API pricing is per million tokens (input + output). Claude 3.5 Sonnet: $3/M input, $15/M output. GPT-4o: $2.50/M input, $10/M output. Gemini 1.5 Pro: $1.25/M input (≤128K context), $5/M output. For high-volume workloads, batch APIs offer 50% discounts. Fine-tuned or self-hosted open-source models (Llama 3, Mistral) can reduce costs by 80–95%.

What are the key security and compliance considerations for enterprise LLM API usage?

Enterprise LLM deployments require: data residency controls (ensuring prompts don't train the model), PII filtering before prompt submission, audit logging of all LLM interactions, role-based access control for API keys, SOC 2 / ISO 27001 compliance from the provider, and DLP policies to prevent sensitive data exfiltration through AI interfaces.

When should enterprises self-host open-source LLMs versus using commercial APIs?

Self-hosting (vLLM, TensorRT-LLM, Ollama) is justified when: data cannot leave the organization (air-gapped environments), inference volume exceeds $50K/month API cost, fine-tuning on proprietary data is required, latency requirements exceed API SLA capabilities, or compliance mandates on-premises processing. Commercial APIs are preferable for most organizations until volume and control requirements tip the calculus.
