GPT-5.5 Breaks OpenAI's Revenue Records — Codex Doubles in One Week
One week after GPT-5.5 launched, OpenAI declared it the strongest model debut in the company's history. API revenue is growing more than twice as fast as any prior release, while Codex doubled its revenue in under seven days — with enterprise demand for agentic coding tools cited as the primary driver. Three independent X/Twitter intelligence batches converged on the same data points across two days, reinforcing the signal.
What the Source Actually Says
OpenAI's official announcement was precise: API revenue for GPT-5.5 is "growing more than 2x faster than any prior release," and Codex "doubled revenue in under seven days." Enterprise adoption of agentic coding workflows is the explicit growth driver — not consumer uptake, but developers and teams deploying autonomous coding agents at scale.
The developer community is confirming the official metrics organically. Prominent AI engineer @swyx announced he had uninstalled the ChatGPT app entirely, calling Codex a "strict superset" of ChatGPT — a signal that the coding-focused product has fully displaced its parent product in at least some high-signal developer workflows. Codex is also shipping features rapidly: a /goal feature for long-running autonomous tasks, /hatch for gamified AI companions (a social retention layer), and one-click migration tooling from competing environments.
On May 3, Sam Altman revised his own prior emphasis: "I keep thinking I want the models to be cheaper/faster more than I want them to be smarter — but it seems that just being smarter is still the most important thing." This statement, made in the same week GPT-5.5 broke revenue records, closes the loop: the intelligence-first bet is producing measurable enterprise returns.
Strategic Take
GPT-5.5's first-week numbers reframe the market: raw model intelligence still drives enterprise adoption faster than cost or speed optimisation. Builders evaluating AI coding tools should treat Codex's 7-day revenue doubling as a threshold signal — the feature velocity and enterprise traction suggest OpenAI is building an ecosystem around Codex, not just shipping a faster model.
