A public dataset of 64 million steps from 307,416 GitHub cloud agent tasks.

AgentLogs scanned 1,812,362 public repositories and captured agent activity from 35,810, yielding 307,416 tasks, 549,239 sessions and 64,255,174 log entries including prompts, intermediate reasoning, tool calls and token usage (arXiv 2608.29204). Prior datasets captured what agent pull requests looked like when finished. This captures the process, which is the raw material for studying failure modes and per-task cost empirically.
