OpenAI launches the ChatGPT Plus subscription

Background

ChatGPT reached about 100 million monthly users two months after its launch, a mark it passed shortly before the paid plan was introduced^[3]. Serving a free chatbot to an audience that size is expensive: every reply is produced by large models running on servers, and demand is uneven, concentrating in busy periods when many people are using the service at once. The result is a familiar tension for a free product — the people who use it most are the ones most likely to run into its limits.

The launch

On 1 February 2023, OpenAI launched a pilot paid subscription plan called ChatGPT Plus^[1]. It cost $20 a month^[2]. The word "pilot" mattered: the company presented the plan as a test rather than a finished product line, and it did not withdraw the free version.

What the plan offered

OpenAI listed three benefits for subscribers: general access to ChatGPT even during peak times, faster response times, and priority access to new features^[5]. Each of these addresses a different kind of limit. Access at peak times is about availability — whether the service lets you in when it is busy. Response time is about speed. Priority access is about timing: subscribers see new capabilities before other users do.

OpenAI also said it would keep offering free access to ChatGPT, and that the subscription would help support that free access^[5]. In other words, the paid plan was described not as a replacement for the free product but as a way of supporting it.

New features arrived through the subscription

The promise of priority access shaped what happened next. Plus subscribers were the first to get GPT-4 in ChatGPT, on 14 March 2023^[3]. On 27 April 2023, "GPT-3.5 with Browsing" (alpha) became available to Plus users^[4]. Both releases show how the subscription worked in practice: it was not only a way to buy speed and availability, but also the channel through which new features reached users first.

Who was using it, and for what

OpenAI said millions of people had given feedback during the research preview, with uses including drafting and editing content, brainstorming, programming help and learning^[5]. That list describes ordinary knowledge work — writing and revising text, generating ideas, getting help with code, studying — rather than laboratory demonstrations. A subscription aimed at those users is a subscription aimed at people who rely on the tool often enough to care about getting in during busy hours and getting answers back quickly.

What it changed

The launch gave ChatGPT a two-tier structure: a free tier, and a paid tier that bought availability, speed and early access to new features^[1][5]. It also put a visible price on the computing costs behind a large language model, at $20 a month^[2]. And the order in which later capabilities arrived — GPT-4 first to Plus subscribers^[3], browsing opened to Plus users^[4] — made the subscription part of how the product developed, not just an add-on at the checkout.
