Claude Code2 Configurations
This page groups Configurations under one friendly model name for navigation only. Each Configuration below is a separate immutable record: differing tool versions, exact model IDs, reasoning settings, or plugins are never merged, and an inactive Configuration keeps its published history.
2 published Revisions, preserved from 2 published Runs across every Configuration on this page. These counts describe how much is archived, not how good anything is.
An exact model and reasoning setting per Configuration and no subagents, but no shared sandbox: Codex used its own, and Claude Code and OpenCode had none until 2026-09-24. Runs are compared only within one protocol. How the protocols differ
Operator-attested: the Configuration, tool version, displayed model, and elapsed time were recorded by the operator from what the tool showed at Run time. They are not independently verified. An exact model ID appears only when the tool exposed one; it is never inferred.
