GPT on OpenGradient

    GPT without the OpenAI account.

    GPT-5.5, GPT-5 and the fast minis, served through the anonymity layer: your prompts arrive at the model stripped of identity, and you pay per message instead of $20 a month. Claude, Gemini, Grok and the uncensored open models share the same picker.

    The usual way has a catch

    Using GPT normally means an account that knows you.

    The official apps tie every conversation to your account, your payment method and your history - and bill you a monthly plan for one vendor's models. The models are excellent; the envelope is the problem.

    One vendor, one subscription

    Model loyalty enforced by billing: comparing labs means stacking $20 subscriptions, so most people never compare at all.

    Identity rides along

    Hosted access normally attaches your account to every prompt. The anonymity layer here splits identity from content - structurally, not by policy.

    Here's how OpenGradient is different

    The default model, de-identified

    Flagship sizes, no hardware

    The full-size models - not the quantized compromises - served from the studio picker alongside every other family, switchable mid-conversation.

    Pay per message

    No subscription: each message is priced by the model you use and shown before you send. 1,000 credits = $1.

    Anonymous by architecture

    Encrypted relays and secure enclaves ensure no party - including us - holds both your identity and your prompts.

    The anonymity layer

    GPT, minus the file on you.

    Not a policy promise - a protocol. No single party, including us, ever holds both your identity and your question.

    Read the full security architecture
    1. Encrypted on your device

      Messages are encrypted locally before they leave your browser.

    2. Anonymized by Oblivious HTTP

      Network relays split who you are from what you're asking. No one sees both.

    3. Unlocked only in a secure enclave

      The model reads your prompt inside attested hardware that never learns who sent it.

    ChatGPT, Claude, and Gemini - one tab away.

    When the task calls for a frontier model, switch mid-conversation. Same anonymity layer, same chat, no extra subscription.
