User claims fleeting glimpse of "GPT-6 Astra" with 3 reasoning tiers in ChatGPT
Possible_Statement84 · reddit · 2026-09-28
A Reddit user reports briefly seeing an experimental "gpt-6 astra" entry in the regular ChatGPT model picker, offering light/extended/heavy reasoning modes. Selecting it silently rerouted the chat to work mode with gpt-6 luna at max reasoning, and the option vanished unreproducibly. The author suspects an internal/ab-test UI config leak, noting the tier labels don't match currently documented astra/luna options.
