*Topic: Agentic workloads. Period: Oct 2026. Last updated 2026-11-11.*

## Why it matters

The finish_reason mix shows what a provider is used for. A high tool_calls share means agent traffic; a high stop share means chat or batch completions.

## Questions this answers

- Which provider serves the most agentic traffic?
- What is the finish_reason mix by provider?
- How often do responses hit the length limit?

## Key findings

1. Vertex (Claude): 34% tool_calls, 53% stop.
2. Sference: 31% tool_calls, 60% stop.
3. DeepSeek: 31% tool_calls, 64% stop.
4. Azure: 25% tool_calls, 53% stop.
