Function calling
Tool use + MCP
/ Pick OpenAI when
- Heavy structured data extraction workloads
- Cost-sensitive bulk inference
- Existing Azure enterprise commitments
- Needs for o-series reasoning
/ Pick Anthropic when
- Long-document analysis (contracts, reports)
- Agentic workflows with tool use
- Nuanced reasoning on safety-sensitive content
- MCP-standardized integrations
Our take
We route between both in every production system. OpenAI for structured extraction and bulk tasks, Anthropic for long context and agentic work. Single-vendor AI architectures are a risk we don't recommend.
