GPT-5.6 Release Tracker
Confirmed facts, kept separate from the rumors
OpenAI's next model GPT-5.6 is approaching, and the web is full of hard-to-verify leaks. We list only officially traceable facts, clearly label rumors and predictions, and keep this page updated — live on QCode.cc the day it launches.
As of June 2026, OpenAI has made no official announcement of GPT-5.6 — no model card, no API, no official benchmarks or pricing. Everything on this page that isn't marked 'Confirmed' is rumor or prediction; treat it with caution.
✅ Confirmed facts
The only claims currently backed by traceable evidence.
OpenAI hasn't announced it
As of June 2026, OpenAI has made no official statement about a model named 'GPT-5.6'. It appears nowhere on the website or in the API docs.
Surfaced in Codex logs
Developers reported GPT-5.6 briefly appearing as a single canary entry in OpenAI Codex's internal rollout-mapping logs, then disappearing — usually a sign of internal testing, not a public release.
GPT-5.5 is still current
OpenAI's current public flagship remains GPT-5.5 ($5/M input, $30/M output, ~1M context). If GPT-5.6 ships, it is expected to be a direct upgrade.
🔮 Rumors & predictions
From leaks, user probes and prediction markets — none confirmed by OpenAI. For reference only.
Rumored 1.5M-token context
Per ChatGPT Pro OAuth user probes, GPT-5.6 context may reach 1.5 million tokens (about +43% over GPT-5.5). Unconfirmed by OpenAI; real retrieval quality awaits official benchmarks.
Rumored codenames ember/beacon/iris-alpha
Multiple leaks mention internal codenames ember-alpha, beacon-alpha and iris-alpha. The 'alpha' suffix implies pre-release status and possibly distinct variants (flagship vs lite). None officially confirmed.
Rumored stronger frontend UI generation
Leaked screenshots reportedly show the model generating a note-taking app UI called 'Lumen Notes' from a minimal prompt, hinting at improved frontend generation. Authenticity and limits both unconfirmed.
Markets bet on a June launch
Prediction markets like Polymarket price GPT-5.6's odds of a public release before June 30, 2026 at roughly 80–89%, with conservative views pointing to July. These are market odds, not an official timeline.
Note: every number in this section (1.5M, 43%, 80–89%) comes from third-party leaks or prediction markets. OpenAI has never published any benchmark, pricing or release date for GPT-5.6. Do not treat these as established facts.
When will it launch?
Nobody knows for sure. Prediction markets treat 'before end of June 2026' as the likely window, but OpenAI rarely pre-announces. The safest move: stay tuned and have an access path ready to switch on launch day — which is exactly what QCode.cc is for.
How to use GPT-5.6 the moment it ships
QCode.cc is a unified AI-coding API platform for developers in China; we add OpenAI's new models as soon as they launch.
Onboarded at launch
Every time OpenAI ships a new model, we onboard it as fast as possible — no re-registering accounts or changing your toolchain.
One key, many models
A single QCode API key calls both the GPT and Claude families across Codex CLI and other clients, switchable any time.
Stable access in China
Access endpoints optimized for mainland China — low-latency, stable connections, no self-hosted proxy needed.
GPT-5.6 FAQ
Has GPT-5.6 been released?
No. As of June 2026, OpenAI has not officially released GPT-5.6 and has published no API, benchmarks or pricing. The only traceable evidence is its brief appearance in internal Codex logs.
How large is GPT-5.6's context window?
Not officially disclosed. Some user probes suggest up to 1.5 million tokens, but OpenAI has not confirmed this. For reference, the current GPT-5.5 is about 1 million tokens.
When is GPT-5.6 expected to launch?
No official timeline. Prediction markets put the odds of a release before end of June 2026 at roughly 80–89%, with conservative estimates of July. Defer to OpenAI's official announcement.
Will GPT-5.6 work on QCode.cc?
Yes. We will evaluate and onboard it as soon as OpenAI officially releases it; you'll call it from Codex CLI and other tools using the same QCode API key, with no account change.
