Brief

Researcher @andreabalducci observed an overnight change in the Codex multi-agent routing: between Aug 2–3 Luna processed 42–49% of their tokens (757M on Aug 3). From Aug 4 onward new tasks run on v2, with Luna still usable interactively but removed as a subagent and replaced by Terra for subagent workloads.

Why it matters

On Aug 2–3, the Codex multi-agent system routed 42–49% of @andreabalducci's tokens to the Luna agent, peaking at 757 million tokens on Aug 3.

Key details

  • Starting Aug 4, new tasks default to v2: Luna remains selectable for interactive use but is no longer available as a subagent; Terra now fills Luna's previous subagent role.
Source evidence

Something changed in Codex multi-agent overnight. On Aug 2–3, Luna handled 42–49% of my tokens (757M on Aug 3). Since Aug 4, my new tasks use v2: Luna is still selectable interactively, but unavailable for subagents; Terra takes its place.
