Reddit User Claims Only GPT-6 Instant Is Real GPT-6; Medium and High Still Act Like 5.6
Deadline_Zero · reddit · 2026-10-09
A Reddit user reports that in ChatGPT's new Chat mode, only the Instant tier behaves as real GPT-6: asked what model it is, Instant says GPT-6 while Medium and High claim to be 5.6. Response style tests also suggest Medium/High match 5.6 rather than the Intelligent UI demos shown by OpenAI, despite documentation stating all tiers run GPT-6. Unclear whether it's account-specific, but similar reports are circulating.
