When was GPT-5.5 released?

OpenAI released GPT-5.5 on 23 Apr 2026. It is available through the qynio gateway.

Does GPT-5.5 support zero data retention?

Not by default. See the per-route data-handling section for each route's logging stance and retention window.

Where is GPT-5.5 hosted?

GPT-5.5 runs on both EU and US hosting routes through the qynio gateway. Pick the route that matches your residency requirement.

Is GPT-5.5 trained on prompts and outputs?

No. Every hosting route for GPT-5.5 is configured so customer prompts and outputs are not used to train models by default.

Is a no-KYC deposit available for GPT-5.5?

Yes. A no-KYC Data Processing Agreement is available on at least one route serving GPT-5.5. Contact hello@qyn.io to receive it.

GPT-5.5

by OpenAI

All OpenAI releases

GPT-5.5 is OpenAI's most capable model for real-world work, understanding what users are trying to do faster and carrying more of the work itself. It excels at writing and debugging code, researching online, analyzing data, creating documents and spreadsheets, operating software, and moving across tools until a task is finished. With a 1M token context window and vision support, GPT-5.5 covers reasoning, tool use, structured output, web search, and computer use. It performs better than GPT-5.4 across nearly every measured evaluation while matching GPT-5.4's real-world serving latency, so it is more capable without being slower. Rather than requiring careful management of every step, GPT-5.5 accepts messy multi-part tasks and handles planning, tool selection, verification, and navigation through ambiguity more autonomously. That combination makes it well suited to developers building agentic systems.

Uptime and availability

GPT-5.5 runs on 2 independently monitored routes through the qynio gateway. A direct integration leaves you on one of them, the gateway serves whichever is healthy.

100%effective uptime, last 30 days

Averaged across these routes on their own, a single provider reached 98.03% over the same window.

Daily status through the gateway, which serves each request from whichever route is healthy.

2 monitored providers serve GPT-5.5.

Measured over the last 30 days from each provider's official status feed via StatusGator. Refreshed hourly. See uptime for every provider qynio monitors.

Data handling per route

Each route hosting GPT-5.5 has its own privacy posture, residency, and no-KYC terms. Postures are maintained by qynio with a last-verification timestamp.

Get started

Call GPT-5.5 through the qynio gateway with one API key. Let your coding agent set it up, or call it directly — qynio is drop-in compatible with the OpenAI, Anthropic, and Google AI SDKs.

Set it up with your agent

Copy this and paste it into a coding agent like Claude Code, Cursor or Codex and it'll wire up qynio for you.
