How many API calls does a single coding session make? In April 2026, Claude Code has the deepest sessions at 16 median calls per trace and reaches 209 calls at P95, reflecting complex multi-step coding workflows. Roo Code sessions are shallower at 11 median calls but more numerous (6,247 traces vs 594 for Claude Code).

Why it mattersSession depth is a proxy for agentic autonomy. Deeper sessions mean the agent is performing more steps before returning control to the developer. Claude Code P95 of 209 calls per session means the top 5% of coding tasks involve 200+ round trips to the model. This drives both cost and latency accumulation.
