Open ChatGPT (GPT-5 model) on ChatGPT Plus account.
Request any image generation (e.g., generate a photoreal image of a dog in daylight).
Observe: no output, no error, and increasing UI latency.
Attempted on Chrome 129 and Safari 17 on macOS Sequoia 15.6.1 (M2) — identical result.
Retried multiple sessions; same across browsers, devices, and stable fiber (433 / 176 Mbps).
Tracked log file available
GPT-5 image generation should execute normally, return a generated image, and display confirmation logs or processing progress without significant lag.
No image is generated; response window stalls for 60–120 s with “Page Unresponsive” alerts, connection-lost banners, or delayed text responses.
No error message or completion ID returned.
GPT-4o fallback works intermittently but ignores detailed prompt directives (lighting, realism parameters).
