GPT-5.5 powers OpenAI's strongest launch yet

One week after launch, OpenAI says GPT-5.5 is its strongest model debut yet. API revenue is growing more than 2x faster than any previous release, and Codex revenue doubled in under seven days as enterprise demand for agentic coding tools keeps climbing.

// ANALYSIS

This looks less like a benchmark victory and more like proof that agentic coding is becoming a real revenue engine for OpenAI.

–Faster API growth suggests GPT-5.5 is converting into usage, not just headlines
–Codex doubling revenue in a week is the sharper signal: enterprises are paying for workflow automation, not chatbot novelty
–The launch reinforces OpenAI’s strategy of coupling model releases with product surfaces that monetize immediately: ChatGPT, Codex, and the API
–If the demand holds, GPT-5.5 could set the cadence for how frontier models are sold going forward: quality plus operational utility, not raw capability alone
