What We Looked At

  • API reliability
  • Tool/function calling
  • Enterprise integrations
  • Safety & compliance
  • Cost at scale

API reliability and SLAs

For workflows that actually matter — customer-facing products, internal tools that teams depend on — uptime isn't optional. Both OpenAI and Anthropic offer enterprise tiers with priority queuing and SLA commitments. In practice, your decision often comes down to which cloud you're already on: OpenAI plays well with Azure, while Anthropic sits cleanly on AWS Bedrock. Don't underestimate vendor relationship politics when teams have existing cloud contracts.

Prompt caching for cost control

Prompt caching is the most underrated cost lever in production AI. Both Claude and GPT-4o support it, and if you're running any application with a consistent system prompt, you can cut input token costs by 80–90%. At any meaningful scale, this compounds fast. A system prompt you're sending 100,000 times a day suddenly costs almost nothing. Get caching in place first, then worry about which model tier makes sense.
