ChatGPT vs Plugsky — a fair comparison

Both ChatGPT and Plugsky offer powerful AI chat. But ChatGPT locks you into OpenAI's models with rate caps and per-token API billing. Plugsky gives you 31+ models through one OpenAI-compatible API with unlimited calls and flat pricing. The table below shows the differences that matter for teams, developers, and enterprises.

The real cost of ChatGPT API vs Plugsky

ChatGPT Plus is $20/mo per person with rate limits. The OpenAI API charges per-token ($2.50-$15/MTok). A team of 10 paying for Plus = $200/mo just for subscriptions. On Plugsky, unlimited usage for the same team with access to 31+ models is available at flat-tier pricing that doesn't surprise you at month-end.
