Cheap GPT 5.4 API
OpenAI's GPT is the generalist that handles almost everything — code, long reasoning, images, structured output. If you'd rather not juggle a zoo of models, one GPT covers most of it. Native to Codex and Cursor, and it does function calling and JSON schemas without fuss. Through cheapai it's available via an OpenAI-compatible API from $0.37/1M per 1M tokens, roughly 85% cheaper than OpenAI's official price. No VPN, pay in ₽, USDT or by card, and it works out of the box with Cursor, Claude Code, Cline and any OpenAI SDK.
| Input / 1M | $0.37 |
