GPT-5.6 Misspells Email Address, Then Hallucinates a Post-Hoc Excuse

WolframRvnwlf · x · 2026-08-04

A user reported that while drafting an email, GPT-5.6 Sol xhigh misspelled their email address. Interestingly, the model immediately caught the mistake in the same message and offered a plausible explanation: claiming it generated the address anew instead of copying it exactly from a verified source.

The user pointed out that this is clearly a hallucinated, post-hoc excuse, as the AI does not actually know why the error occurred. Such typos typically point to underlying inference performance optimizations or quantization issues.
