Questions, answered
Is this the real GPT-5.5 from OpenAI?
Yes. Same model, same weights, byte-for-byte equivalent outputs. Hypereal is an aggregator that resells GPT-5.5 capacity at a discount.
Do I need a VPN or special account to use it?
No. Hypereal is region-agnostic — works from any country with no VPN, no waitlist, no $5 minimum spend tier.
Are vision and tool use supported?
Yes. Image input, function calling, parallel tool calls, JSON mode, and SSE streaming all match the official OpenAI spec.
How does the OpenAI SDK work with Hypereal?
Set base_url=https://api.hypereal.cloud/v1 and api_key to your Hypereal key. Everything else — model names, request shape, response shape — stays identical to OpenAI.
How does billing work?
Pay per token using credits. 100 credits = $1. Buy from $10, no subscription, no monthly reset. Card and crypto accepted.
